The pipe rust prevention device "NMR Pipe Protector" was featured on TV Tokyo's economic information program "World Business Satellite (WBS)." The rust prevention effect of the water from the NMR Pipe Protector has small clusters, which promotes the growth of vegetables, leading to verification in the agricultural field. At "Mitsu Village" in Himeji City, Hyogo Prefecture, NMR Pipe Protectors are installed in the pipes that supply water to the greenhouses. In the program, the weight of tomatoes grown with regular water was compared to those grown with water from the supply pipe equipped with the NMR Pipe Protector, and on average, the latter tomatoes were 16 grams larger. From previous verifications, it has been found that growing tomatoes with water from the supply pipe equipped with the NMR Pipe Protector increases the yield by approximately 7 percent. In this way, the NMR Pipe Protector is expected to leverage its ability to change the properties of water and expand into various fields. *You can download the materials for free. *Please feel free to contact us first.

The red rust prevention device "NMR Pipe Protector" is a product with excellent functionality that reduces red rust to black rust and strengthens piping. Red rust has the property of generating red water and corroding pipes until they become severely deteriorated. Co-op Nomura Minami Ishikiri installed the NMR Pipe Protector in August 2001, marking its 24th year. After 15 years, a deterioration diagnosis survey of the piping was conducted. When the drainage pipes on the secondary side of the elevated water tank and inside the residences were inspected, it was found that there was almost no progression of red rust due to internal deterioration in both the water supply and drainage pipes. Thanks to the effect of the NMR Pipe Protector, red rust had hardly progressed, and its surface had turned to black rust, ensuring proper rehabilitation of the piping. Similarly, the drainage pipes showed almost no progression of red rust, earning high praise. *For more details, please refer to the PDF document or feel free to contact us.*

In the condominium "Cosmo Kajigaya Le Seine," where the NMR Pipe Protector has been introduced, polyvinyl chloride lined steel pipes (VLP) were used for the water supply piping. Polyvinyl chloride lined steel pipes (VLP) refer to pipes that are internally coated with polyvinyl chloride. While the joints of the pipes are prone to red rust deterioration, the straight sections are excellent in durability and corrosion resistance, and are currently used in most buildings' water supply pipes. However, this water supply piping has high maintenance costs, and after several decades of installation, measures against water leaks due to red rust at the joints become necessary. Many water supply pipes experience issues such as red rust blockage at the joints, water leaks, and deterioration of water quality after twenty years. The NMR Pipe Protector converts red rust into black rust, resolving these issues. Unlike pipe replacement work, the NMR Pipe Protector can be installed without water service interruption, transforming the red rust inside the water supply pipes into black rust that strengthens the pipes. By introducing the NMR Pipe Protector, red rust becomes inert black rust, extending the lifespan of the pipes by over 40 years. *For more details, please refer to the PDF materials or feel free to contact us.

The red rust prevention device for piping, "NMR Pipe Protector," has obtained patents and registrations in the United States and major countries around the world after undergoing rigorous patent examinations abroad regarding its practicality and other factors. On February 16, 2004, the first installation in the UK was at Addenbrooke's Hospital, affiliated with the University of Cambridge. The NMR Pipe Protector holds a patent in the UK and established its reliability through presentations at conferences related to "corrosion," leading to its installation upon recommendation from the University of Cambridge. The hot water pipes at Addenbrooke's Hospital experienced leaks due to bacterial corrosion and red rust deterioration just three years after the piping was updated. However, after the installation of the NMR Pipe Protector, red rust in the hot water piping made of galvanized steel was prevented in just 11 days. The iron ion concentration due to red rust in the hot water decreased from 1.07 mg/L before installation to 0.188 mg/L after 11 days, falling below the water quality standard of 0.2 mg/L. The transformation of red rust in the hot water pipes to black rust with a volume reduction to one-tenth confirmed the rust prevention effect of the NMR Pipe Protector.

In August 2001, we introduced the "NMR Pipe Protector" to the Co-op Nomura Minami Ishikiri condominium in Wakabayashi Ward, Sendai City, Miyagi Prefecture. After 15 years of implementation, an investigation into the deterioration of the piping was conducted. The investigation involved removing the water supply pipes on the secondary side of the elevated water tank and inside the residences, as well as the drainage pipes. It was evaluated that "there was almost no red rust due to internal deterioration of the water supply pipes, and there were no blockages; it was confirmed that the surface had turned black due to rust, and pipe rehabilitation had been carried out." The condominium's maintenance director stated during an interview, "Not only the water supply pipes but also the drainage pipes have been extended in their lifespan, and there are no plans for updates in the long-term repair plan." He added, "As the building ages, it will only become more financially challenging in the future, so the benefits of not having to update the water supply pipes are immeasurable." *For more details, please refer to the PDF document or feel free to contact us.

On January 12, 2007, in one of the six pump rooms located within Buckingham Palace, only one pump room supplying Her Majesty's room had the 'NMR Pipe Protector' installed for the air conditioning hot water piping and the hot water supply piping. Before the installation of the NMR Pipe Protector, the iron ion concentration in the circulating hot water within the air conditioning hot water piping for Her Majesty's room was measured at 16.6 mg/L, indicating a high iron ion level and a significant presence of red rust within the piping. Subsequently, 24 days after the installation of the NMR Pipe Protector, the iron content in the hot water within the air conditioning hot water piping decreased to 0.455 mg/L. The piping was completely protected from red rust by the NMR Pipe Protector, and the lifespan of the piping was extended, which has been greatly appreciated by those associated with Buckingham Palace for security reasons. *Customer feedback (customer testimonials) and other PDF materials are available for free! *Please feel free to contact us first.

To extend the lifespan of existing piping to match the lifespan of the building, if the red rust occurring inside the pipes can be converted to black rust without flushing it away, the lifespan of the pipes can be prolonged to that of the building. When extending the lifespan of pipes, methods such as pipe cleaning or sandblasting to remove red rust can damage the interior of the pipes, reducing their strength. With our internal red rust prevention device, the 'NMR Pipe Protector,' red rust can be converted to black rust without directly contacting the water inside the pipes. By utilizing NMR (nuclear magnetic resonance), it is possible to prevent the deterioration of red rust inside the pipes and even rehabilitate and strengthen the pipes. It is suitable for preventing red rust in water supply pipes (vinyl-lined steel pipes) and air conditioning hot and cold water pipes (galvanized steel pipes), as well as for the rehabilitation and strengthening of pipes. *For more details, please refer to the PDF materials or feel free to contact us.

In the year 2000, at a major DPE factory that was 35 years old at the time, the pipe lifespan was diagnosed to be 2 months, and our 'NMR Pipe Protector' was introduced into the water supply piping. The iron content in the water that had been stagnant overnight was 0.5 mg/L before the introduction, which was unsuitable for water used in DPE. However, just 6 days after the introduction of our product, the iron content in the water decreased to less than 0.05 mg/L, a tenth of the previous level, due to the black rust formation from red rust. Since then, the water quality has further improved, with the iron content in the water dropping to below 0.03 mg/L, confirming the effectiveness of red rust prevention. As of 2019, the water quality has been maintained. Additionally, no new leaks have occurred since the introduction.

In addition to pipe rehabilitation, there is the "NMR method," which uses our internal rust prevention device, the "NMR Pipe Protector," to reduce red rust to insoluble and passive black rust. Vinyl-lined steel pipes are commonly used for condominium water supply (distribution) piping, where the straight sections do not deteriorate from red rust, but only the joints do. By converting this red rust to black rust, pipe replacement becomes unnecessary, reducing costs to 1/5 to 1/10. The NMR Pipe Protector utilizes free electrons in the water to convert internal red rust to black rust. Since the NMR Pipe Protector is installed on the outside of the pipes, it does not come into direct contact with the water inside, making it hygienic and safe. Through on-site surveys conducted by our technical workers, we can implement our product at suitable installation locations, enabling appropriate pipe rehabilitation throughout the entire piping system. The NMR method has obtained a patent as a groundbreaking pipe rehabilitation technique and has been recognized through research papers presented at the "Asia-Pacific Corrosion Society" and the "Japan Society of Corrosion Engineering." It has been highly evaluated for its water quality safety and has been adopted in many renowned hospital facilities around the world. The NMR Pipe Protector comes with a rust prevention effect guarantee, allowing for worry-free implementation. *For more details, please refer to the PDF or contact us.*

The water supply pipes in buildings such as condominiums are made of vinyl-lined steel pipes, so the straight sections do not deteriorate, and only the joints experience red rust deterioration. Since there is no change in the color of the water coming from the faucet and no red water is produced, it is difficult to notice the red rust deterioration inside the pipes. Our company will first conduct an on-site inspection using an endoscope to investigate the condition of the red rust deterioration, and based on that, we will propose the introduction of the optimal "NMR Pipe Protector." With this product, it is possible to prevent red rust deterioration throughout the entire piping, including the joints. By introducing this product, it is possible to eliminate the need for costly pipe replacement expenses, which can be a significant financial burden for customers within limited repair budgets, and extend the life of existing pipes for over 40 years, thereby prolonging the lifespan of the pipes until the building's lifespan ends. *For more details, please refer to the PDF document or feel free to contact us.

The costly aspect of large-scale repairs in condominiums is the "repair of the water supply pipes." By introducing the rust prevention device 'NMR Pipe Protector' into the water supply pipes, it is possible to completely prevent rust deterioration inside the pipes and extend their lifespan by over 40 years. As a result, it eliminates the need for costly pipe replacement work during large-scale repairs, significantly reducing the costs associated with condominium renovations. Additionally, the introduction does not require any water outage work, and it can be implemented at about one-fifth to one-tenth of the cost of updating the condominium's water supply pipes, with no maintenance or running costs required after installation. For these reasons, by adopting this product, you can save approximately 80-90% of the costs associated with large-scale repairs of the water supply pipes. *For more details, please refer to the PDF materials or feel free to contact us.

The condition of corrosion deterioration of the screw threads cannot be determined from the exterior of the building. If corrosion deterioration of the screw threads progresses unnoticed, it can cause pipes to come loose and lead to water leaks due to shocks during earthquakes. To maintain the seismic strength of the piping, it is necessary to perform anti-corrosion treatment inside the pipes before the screw threads are reduced due to red rust deterioration. Our anti-red rust device for piping, the 'NMR Pipe Protector', can improve various red rust issues inside the pipes by reducing red rust to black rust. Not only does it provide anti-corrosion effects, but the transformation of red rust to black rust also strengthens and rehabilitates the piping. For the safety of our customers, it is wise to reconfirm the seismic strength of the building's piping and take prompt action to prepare for earthquakes at any time. *For more details, please refer to the PDF document or feel free to contact us.

The British Museum has undergone multiple renovations over the years, but the building is over 264 years old. It is an important museum that needs to continue to exist in the future, but the issue of building deterioration cannot be avoided. One of those issues was the concern of leaks due to the deterioration of the heating hot water piping from red rust. In March 2016, we verified whether the 'NMR Pipe Protector' is truly an effective measure against red rust in piping by installing one unit on the air conditioning hot water piping and conducting iron content tests in the same circulating hot water before and after installation. Before the installation of the NMR Pipe Protector, the iron content in the water was very high due to red rust. Three weeks after installation, it measured 3.44 mg/L, and five weeks after installation, it dropped significantly to 0.2 mg/L, demonstrating the effectiveness of red rust prevention as it matched the drinking water standard of 0.2 mg/L. It has been recognized that if the NMR Pipe Protector continues to be used, the lifespan of the piping can be extended to match the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.*

The Royal Garden Hotel London is beloved by travelers from around the world as one of the world's leading five-star hotels. Constructed in 1965, by 2007, it had been 42 years since its establishment, and the deterioration of the hot water supply pipes had progressed. Due to the use of iron pipes, internal red rust corrosion had advanced, resulting in relatively dark red water coming out of the taps every morning. In response, three "NMR Pipe Protectors" were installed on the main hot water supply pipe in the boiler room. Furthermore, water quality tests were conducted before installation, two weeks after installation, and then monthly for 12 months to measure the iron content in the water due to red rust. The results showed a significant decrease in the iron content in the water immediately after installation. Since the effectiveness of rust prevention was quantitatively proven, the hotel also installed NMR Pipe Protectors in the air conditioning piping. Ultimately, while the cost of pipe replacement was approximately 1.5 billion yen, the total cost of the NMR Pipe Protectors was about 30 million yen, resulting in a cost that was 1/50 of the replacement cost. In terms of cost-effectiveness, it far exceeded the hotel's expectations. *Customer testimonials (customer recommendation letters) and other PDF materials are currently available for free! *Please feel free to contact us first.

The "NMR Pipe Protector" is a groundbreaking device for apartments and hospitals struggling with red rust issues in their piping, and it has received great acclaim. The introduction cost of the NMR Pipe Protector is about 1/5 to 1/10 of the cost of pipe replacement, allowing for a cost reduction of approximately 80-90%. At "Cosmo Kajigaya Le Seine," the introduction of the NMR Pipe Protector has created financial leeway, and they have begun considering the installation of a new elevator, which was a frequent request from residents. It was deemed financially feasible, and a proposal for the installation of the NMR Pipe Protector along with the new elevator was presented at an extraordinary general meeting and approved. Thus, the introduction of the NMR Pipe Protector brings various benefits to each facility. In addition to its effects on maintaining and improving water quality, it also makes a significant contribution in terms of cost. *For more details, please refer to the PDF materials or feel free to contact us.*

As an example of the introduction of the "NMR Pipe Protector," we present the case of the Royal Bank of Scotland. Branch 250 had been in operation for 18 years and was facing issues with red rust in the air conditioning hot water piping. Due to the high costs of rust inhibitors and a shift towards environmental considerations, the "NMR Pipe Protector" was installed in the air conditioning hot water piping in March 2018. As a result of the installation, the iron content value from red rust in the hot water, which was 1.10 mg/L before installation, was re-examined 9 weeks after the installation of the NMR Pipe Protector, revealing that the hot water was clear and the amount of dissolved iron in the hot water had decreased to approximately 1/3, or 0.41 mg/L. The progression of red rust within the piping also stopped, and the red rust had transformed from a surface state to black rust. The NMR Pipe Protector successfully resolved the issue of red rust dissolving into the water and halted its progression. There is now no longer a concern about the acceleration of piping deterioration due to red rust. Additionally, the coating from black rust has a reinforcing effect on the piping, and it is expected to extend the lifespan of the piping to match the lifespan of the building. *Customer feedback (customer testimonials) and other PDF materials are currently available for free! *Please feel free to contact us first.

The "NMR Pipe Protector" has garnered attention worldwide for its ability to solve the problem of red rust. Every morning, red water would come out from the hot water pipes in Guildhall, London. When we measured the iron content in the water, it was found to be 6.36 mg per liter, indicating significant red rust, which is considerably higher than the water quality standard of 0.2 mg per liter set by UK water regulations. Three weeks after installing the NMR Pipe Protector, the iron content in the water was measured at 0.015 mg per liter. This is a reduction to 1/400 of the iron content before installation, and further measurements taken seven weeks after installation showed a decrease to 0.007 mg per liter, which is less than half of the value three weeks after installation, proving that the red rust had transformed into insoluble black rust in the water. As a result of the drastic reduction in iron content, the red water was eliminated. The existing red rust was reduced to black rust, which strengthened the piping. As long as the building continues to exist, the piping can continue to be used. With the red rust problem in the hot water pipes of Guildhall, London resolved, a letter of recommendation was issued. *We are currently offering free PDF materials such as customer testimonials (customer recommendation letters)!

Kumamoto Red Cross Hospital, being a long-established medical institution, faced issues due to the aging of its facilities. One of the significant problems that cannot be ignored is the "deterioration of pipes due to red rust." One of the issues caused by the deterioration of the air conditioning hot and cold water pipes is "leakage." In advanced medical facilities, leakage can lead to the malfunction of medical equipment and is certainly undesirable from a hygiene perspective. In response, in 2014, the 'NMR Pipe Protector' was introduced as a measure to prevent pipe deterioration, and its effectiveness was recognized, leading to its implementation throughout the entire facility. A water quality survey conducted before the installation of the NMR Pipe Protector revealed that the iron content due to red rust in the hospital's air conditioning hot water was 12.3 mg per liter, indicating significant red rust presence. However, just two weeks after the installation of the NMR Pipe Protector, this level decreased to 0.07 mg, demonstrating a reduction of approximately 82% in concentration, and proving that the red rust had transformed into insoluble black rust in the water. Not only were we able to protect the medical environment from leakage caused by red rust, but we also became able to allocate more budget to other areas. *For more details, please refer to the PDF document or feel free to contact us.*

Currently, at the Imperial Theatre, which was built 56 years ago, the "NMR Pipe Protector" was introduced in 2000 (Heisei 12) to prevent corrosion of the building's piping and to rehabilitate it, as the building reached 34 years of age. The Imperial Theatre building has its own heat source facilities for air conditioning, and the machinery room is located at the deepest point, which is the sixth basement level. Renovations and maintenance of various parts, such as water-based piping that is prone to aging, have been carried out quite frequently, but while exposed piping and equipment in the machinery room have been manageable, the buried piping could not be addressed. The effects of introducing the NMR Pipe Protector have been tremendous; this year marks 56 years since its construction, and the occurrence of red rust inside the piping has been remarkably suppressed. Additionally, there has been no leakage for the past 22 years since the installation, proving that the red rust has transformed into black rust. As a result, the NMR Pipe Protector has contributed to maintaining a comfortable theater environment at the Imperial Theatre, which symbolizes Japan's theatrical culture. *For more details, please refer to the PDF document or feel free to contact us.*

The "NMR Pipe Protector" was installed on the secondary side of the main hot water piping pump in the boiler room located in Area F of the British Museum. Before installation, the amount of red rust in the air conditioning hot water was significantly advanced, measuring 20 mg per liter. After five weeks of installation, the amount of red rust in the water decreased to 0.2 mg per liter, reducing it to one-hundredth, and the effectiveness of preventing red rust through its transformation into black rust was demonstrated. As a result, the British Museum was able to not only avoid damage and the risk of water leaks caused by red rust but also reduce the risk of red rust affecting future exhibits. Due to the high risk of damaging exhibits, construction such as replacing piping systems could not be carried out, and the use of chemicals like rust inhibitors would negatively impact the condition of paintings. Therefore, the NMR Pipe Protector was the only method that the museum could adopt. With the NMR Pipe Protector, there was no impact on the exhibits, and the British Museum was freed from the risks associated with red rust. *For more details, please refer to the PDF document or feel free to contact us.*

Whittington Hospital (affiliated with the NHS) was built in the 1860s, and the building has been deteriorating, with the hot water piping having not been updated for about 30 to 40 years since the last renovation. As it stood, the risk of clogs and leaks due to corrosion in the hot water pipes was high, leading to the decision to introduce the red rust prevention device, the "NMR Pipe Protector." As a result of implementing the NMR Pipe Protector, the occurrence of new red rust has been completely prevented, and there have been no instances of red water, proving that the hot water piping has been significantly extended in its lifespan. Additionally, the interior of the piping is protected from black rust by the NMR Pipe Protector, preventing the progression of red rust corrosion. As long as the NMR Pipe Protector is installed, the piping can be used for the lifespan of the building. [Installation Results] ■ Piping can be used until the lifespan of the building ■ Significant cost reductions achieved ■ No need for water outages * Customer testimonials (recommendation letters) and other PDF materials are available for free! * Please feel free to contact us first.

At that time, Buckingham Palace was using galvanized steel pipes for air conditioning hot water piping and hot water supply piping, but due to deterioration from red rust, partial updates to the piping were being carried out outside of Her Majesty's areas. The circulating hot water in these pipes installed for Queen Elizabeth's room had been reddish-brown from the beginning due to red rust. Therefore, to make this reddish-brown water clear and to prevent red rust, as well as to extend the life of the piping, the "NMR Pipe Protector" was introduced. In the hot water supply piping, the level was reduced from 2.8 mg/L before installation to below 0.018 mg/L, which is less than 1/100, after 24 days, proving its effectiveness in preventing red rust. Additionally, the color of the water became clear, and the NMR Pipe Protector demonstrated its high performance in preventing red rust without reservation. *For more details, please refer to the PDF document or feel free to contact us.*

The "Lions Mansion Koshigaya North" in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010, successfully reducing the cost of pipe maintenance to one-third of the amount originally planned for lining work in the long-term repair plan. Before the installation of the NMR Pipe Protector, and one year, five years, and ten years after installation, the rate of red rust blockage at the dissimilar metal joints, where red rust deterioration progresses the most, was continuously inspected, confirming that the rate of red rust blockage decreased over time. This indicates that the red rust is gradually transforming into black rust, which is one-tenth of its original volume. This has proven that the water supply pipes can be extended to the lifespan of the building. The management association effectively utilized the saved budget for projects such as converting lighting fixtures to LED. In addition to the LED conversion of lighting, the renewal of elevators is also being considered in the future. As a result, the NMR Pipe Protector has become a savior for the condominium. It has significantly reduced the costs of pipe maintenance, allowing the surplus budget to be allocated to other building facilities. **Results of the NMR Pipe Protector:** - No growth of red rust was observed in the endoscopic survey conducted six years after installation. - A reduction in the volume of red rust was noted, indicating that the transformation to black rust is progressing.

The achievements of the NMR Pipe Protector in preventing red rust deterioration of air conditioning, water supply, and hot water piping in numerous famous facilities in the UK, such as Buckingham Palace, Windsor Castle, the British Museum, the City Hall of London, the University of Cambridge, City University of London, Harrods, the BBC, Whittington Hospital (NHS), Addenbrooke's Hospital, the Mandarin Oriental Hotel, the Royal Garden Hotel, and Marriott Hotels, have been recognized. The 'NMR Pipe Protector,' which has solved the red rust problem in global structures with its excellent rust prevention technology, has been selected as one of the top 10 rust prevention technologies in the world, and its high level of technology has been widely acknowledged. The NMR Pipe Protector is a groundbreaking rust prevention technology that realizes four advantages: extending the lifespan of existing piping, improving blockages within pipes, no running costs, and no need for extensive construction or water outages. Moreover, the NMR Pipe Protector is not only targeted at global structures and important facilities but also has a wealth of implementation experience in general facilities such as condominiums.

The piping anti-rust device "NMR Pipe Protector" was introduced on the Tokyo MX business program "Corporate Spirit." This product has the function of transforming red rust into black rust. By reducing the size of water aggregates and utilizing free electrons in the water, it reduces red rust in the piping to black rust. While suppressing the occurrence of new red rust, it reduces existing red rust to black rust, thereby strengthening the piping itself. Black rust forms a dense film on the surface of iron, protecting it from red rust, which corrodes iron. It has been used as a rust preventive since ancient times and is still used today for coatings on iron products such as Nambu iron kettles and Chinese woks. This product leverages the advantages of black rust to extend the lifespan of piping.

It is said that plastic waste polluting the oceans amounts to about 8 million tons. Developing countries with densely populated cities like Indonesia and Vietnam are major contributors to the marine plastic waste problem, as they consume large quantities of bottled beverages, many of which flow into the oceans through rivers and other waterways. The high consumption of bottled beverages is due to the unsuitability of tap water for drinking. If the water quality issues of tap water in developing countries can be resolved, there is a prospect of improving the marine pollution problem caused by plastic waste. In this regard, our company’s uniquely developed rust prevention device for pipes, the "NMR Pipe Protector," is highly anticipated. This product can resolve the rust problem in water pipes faced by developing countries at a cost of one-tenth to one-twentieth of pipe replacement, improving the water quality to make it drinkable. The marine pollution caused by plastic waste, which has become a global issue, can be significantly improved by installing the "NMR Pipe Protector," a product born from Japan's advanced technological capabilities, in urban areas of developing countries. *For more details, please refer to the PDF document or feel free to contact us.*

The NMR Pipe Protector has been widely adopted as a device for preventing red rust in piping and extending the lifespan of pipes, and it has recently gained attention in water distribution pipes of water supply agencies. At the Japan Water Works Association's water research presentation held in 2013, the Yokohama City Water Bureau published a paper reporting the results of a demonstration experiment showing that the use of this product can suppress the decrease in chlorine concentration in tap water. This matter was also reported as an article in the Japan Water News. The initial verification confirmed the reduction of iron ion levels in the water and the increase in residual chlorine concentration before and after installation in the water supply pipe within the Tsurumi water reservoir's associated housing. Next, a comparison of residual chlorine concentrations was conducted, revealing that before installation, the chlorine concentration was 0.5 PPM in the test pipe located 10 meters from the main pipe, 0.3 PPM at 60 meters, and 0.2 PPM at 135 meters, indicating that the residual chlorine concentration decreased with increasing distance due to red rust in the piping. After the installation of the NMR Pipe Protector, it was confirmed that the chlorine concentration at 135 meters doubled. From these test results, the effectiveness of suppressing the decrease in chlorine concentration was verified, demonstrating that the NMR Pipe Protector can also be used to prevent red rust deterioration in the main water supply pipes (distribution pipes). *For more details, please refer to the PDF or contact us.*

The building housing the famous bookstore in Shinjuku is always bustling with many people. About 20 years ago, we were troubled by the deterioration of the air conditioning chilled and hot water piping due to red rust. Because asbestos was used in the ceiling, it was practically impossible to carry out piping replacement work. As an alternative to replacing the piping, we introduced the 'NMR Pipe Protector,' a device that can be installed on the outside of the piping to extend its lifespan by over 40 years. A pipe inspection, which involves removing a section of the piping for examination, was conducted 19 months after the installation of the NMR Pipe Protector. The results showed no signs of red rust corrosion on the inner surface of the piping, and the transformation of red rust to black rust was confirmed, indicating a very good condition of the piping. The building is already 57 years old, but the galvanized steel piping used for the air conditioning chilled and hot water system, which has been in use since its completion, has shown no leaks, and a follow-up survey in 2020 confirmed that there has been no occurrence of red rust since the installation of the NMR Pipe Protector. *For more details, please refer to the PDF document or feel free to contact us.*

In the year 2000, 13 years after its completion, it was discovered that there was leakage due to red rust deterioration in part of the chilled and hot water piping of C University Library. The circulating water was mixed with red rust, and the deterioration of the piping had progressed significantly. As a rust prevention measure inside the piping, rust inhibitors were regularly administered, but the red rust deterioration did not stop, and since 1996 (9 years after construction), partial updates of the piping had been underway. However, due to the presence of asbestos in the ceiling of the library, it was difficult to carry out renewal work on the main and branch pipes. Therefore, a red rust prevention device called the "NMR Pipe Protector" was introduced. The NMR Pipe Protector stops the red rust deterioration of the piping and can extend the life of the piping until the building's lifespan, making the removal of asbestos unnecessary and allowing for significant cost reductions. Since the installation work of the NMR Pipe Protector does not require water service interruption, construction could proceed while the building was in use, eliminating the need for the library and surrounding facilities to close. After installation at C University Library, the rust prevention effect in the chilled and hot water piping was confirmed by an increase in the amount of black rust among the red rust. After the introduction of the NMR Pipe Protector, the piping was removed, and quantitative proof of the conversion of red rust to black rust was established through mass analysis of rust samples.

The "Palace Tsurumi" condominium in Tsurumi Ward, Yokohama City, Kanagawa Prefecture, has introduced the red rust prevention device "NMR Pipe Protector" in its 39th year since construction. This is the first implementation of measures against red rust deterioration in the water supply pipes since completion. The management company proposed updating the piping with stainless steel pipes as a measure against water supply pipe deterioration; however, due to the repayment of loans from exterior wall repair work and insufficient reserve funds, it was difficult for the management association to proceed with the pipe replacement. The management association approved the introduction of the NMR Pipe Protector at the general meeting because it came with a guarantee that stated, "If it does not work, we will refund you." To objectively evaluate the red rust prevention effect of the red rust prevention device "NMR Pipe Protector," quantitative effect measurement is conducted. As the red rust gradually transforms into black rust with a volume reduction of 1/10 due to the NMR Pipe Protector, the Palace Tsurumi conducted an investigation of the red rust blockage rate using an endoscope at two locations in the seventh year after installation, showing a reduction in blockage rates of 35.3% and 17.4% compared to before installation. The NMR Pipe Protector demonstrated its rust prevention effectiveness even in piping that had not undergone maintenance for 39 years since completion. *For more details, please refer to the PDF or feel free to contact us.*

At the Legend Hotel Saigon (now Lotte Hotel Saigon) in Vietnam, severe red water emerged from the water supply pipes just six years after its construction. Despite running the water for an extended period, there was no sign of improvement, leaving guests unable to even take showers. The water in Vietnam contains a high level of sulfate components, which reacts with galvanized steel pipes (SGP), making it very prone to red rust formation. In response, in 2008, a red rust prevention device called the "NMR Pipe Protector" was installed in the water supply piping. Before the installation, red water was coming from all the water taps in the hotel. However, about a month and a half later, after conducting water quality checks in the sinks, baths, and toilets of ten guest rooms on the 14th to 17th floors, it was found that the water supply in almost all rooms had become clear, confirming the effectiveness of the red rust prevention. The corrosion of red rust in the water supply pipes was halted, and it was successfully transformed into black rust. This demonstrated that even in water with a high sulfate content that easily corrodes water supply pipes, the conversion of red rust to black rust could be achieved, exhibiting a high level of rust prevention effectiveness. *For more details, please refer to the PDF document or feel free to contact us.*

The Kagurazaka campus of Tokyo University of Science was 26 years old at the time. The water supply pipes were made of PVC-lined steel pipes, and serious red rust blockages had occurred at the joints of the water supply pipes. Before the installation of the NMR Pipe Protector, an inspection of the red rust blockage rate in the toilet water supply piping revealed that the blockage rate was 35%, indicating significant red rust deterioration. After the introduction of the NMR Pipe Protector, a re-inspection was conducted at the same location 10 months later. The results showed that the red rust blockage rate had decreased to 31%, and it was verified that the red rust was gradually changing from a volume of 1/10 of black rust from the surface of the red rust. At Tokyo University of Science, the NMR Pipe Protector was introduced to extend the lifespan of the piping in buildings and facilities that were originally scheduled for replacement in 10 to 15 years.

At the Nihon University College of Engineering campus in Koriyama City, Fukushima Prefecture, the water supply pipes in several research buildings were significantly deteriorated due to red rust, resulting in red water coming from the taps on holidays and the following days. To reduce the future piping renewal costs by 1/5 to 1/10, a red rust prevention device called "NMR Pipe Protector" was installed. The results of an inspection conducted one month after installation clearly demonstrated the excellent performance of the NMR Pipe Protector. The iron content in the water due to red rust decreased to less than 1/10 of the pre-installation level (from 7.8 mg/L before installation to 0.1 mg/L after installation). Originally, the iron content was at 7.8 mg/L, exceeding the water quality standard value of the Water Supply Act (0.3 mg/L), indicating a very serious progression of red rust. However, after installation, it was significantly below that standard value, proving the rust prevention effect through the blackening of red rust and the extension of pipe life. The water quality was remarkably restored to a hygienically satisfactory level. The NMR Pipe Protector is an exceptionally effective rust prevention device that saves energy in creating new piping, thereby reducing environmental burden. *For more details, please refer to the PDF materials or feel free to contact us.

The air conditioning piping in the main block building of the BBC (British Broadcasting Corporation) is 53 years old and has been experiencing leaks due to red rust deterioration. To avoid disruptions in program production during the pipe replacement work, a red rust prevention device called the "NMR Pipe Protector" was installed. The effectiveness of the NMR Pipe Protector in preventing red rust was verified in just about one month. Before installation, the iron content in the circulating water of the cooling water piping in the main block building was very high at 5.53 mg/L, indicating serious red rust deterioration. However, a water quality test conducted 32 days after the installation of the NMR Pipe Protector showed a significant reduction to 0.05 mg/L, which is less than 1/100 of the previous value, confirming the rust prevention effect due to the black rust formation caused by the NMR Pipe Protector. In the Stage 5 building, the iron content was also very high at 3.80 mg/L before the installation of the NMR Pipe Protector, but after installation, it decreased to approximately 0.06 mg/L, which is about 1/63 of the previous value, completely preventing red rust deterioration in the cooling water piping. Even in the 53-year-old BBC building, the high effectiveness of red rust prevention has been proven to prevent leaks and extend the life of the piping. *For more details, please refer to the PDF document or feel free to contact us.*

At Cambridge University, galvanized steel pipes (SGP), which are said to have a lifespan of about 20 years due to red rust, were used for the air conditioning hot water piping. As a result, they were severely troubled by the deterioration caused by red rust, until the introduction of the "NMR Pipe Protector." Before installation, the iron content in the circulating water flowing through the pipes, due to the leaching of red rust, was measured at 43.8 mg/l, indicating a very high level caused by red rust. However, just three weeks after installation, inspections showed that the iron content had decreased to less than half, at 18.0 mg/l. Furthermore, a follow-up inspection about a year after installation revealed that the iron content in the same hot water had decreased to 0.5 mg/l, completely preventing red rust and successfully reducing the iron content to about 1/100 of the level before installation. This is a sufficient value indicating that the corrosion from red rust has stopped and black rust formation has progressed. For comparison, the water quality standard set by the Japan Refrigeration and Air Conditioning Industry Association is an iron content of 1.0 mg/l. The result of 0.5 mg/l at Cambridge University is half of that, confirming the effectiveness of red rust prevention. *For more details, please refer to the PDF document or feel free to contact us.*

At the Millennium Hotel London Mayfair, urgent measures were needed to address corrosion due to red rust in the air conditioning hot water piping. The chosen solution was the 'NMR Pipe Protector,' which can be implemented at less than one-tenth the cost and has a minimal environmental impact while preventing red rust early on. Before installation, the iron concentration in the circulating water of the air conditioning hot water piping showed significant deterioration due to red rust, with a very high value of 15.70 mg/l due to leaching of red rust. A re-inspection six weeks after installation revealed that the iron concentration had decreased to 0.16 mg/l, demonstrating that the amount of iron leached into the water had reduced to about one-hundredth of the previous level, confirming the effectiveness of red rust prevention. Thus, the water quality of the circulating water in the air conditioning hot water piping was restored to a completely acceptable level. One of the major reasons for choosing the NMR Pipe Protector is that it is a very eco-friendly red rust prevention device. It can rehabilitate old piping that has been in use for a long time, extending the lifespan of the building. Replacing the piping would result in significant CO2 emissions due to the disposal of the old pipes, so the NMR Pipe Protector, which allows for continued use of the old piping, has a very low environmental impact. *For more details, please refer to the PDF document or feel free to contact us.*

In 2013, the "NMR Pipe Protector" was adopted at City, University of London, a prestigious university in the UK. The air conditioning hot water pipes used SGP (galvanized steel pipes), which led to the leaching of red rust, causing the water to become brown and murky, and there were occurrences of leaks from the pipe joints. It was necessary to take measures against the deterioration of the red rust in the pipes as soon as possible. After the installation of the NMR Pipe Protector, the progression of red rust completely stopped in just two weeks. The iron content in the circulating water within the pipes, which was 3.41 mg/l before the introduction of the NMR Pipe Protector, remarkably decreased to 0.08 mg/l. Theoretically, over 75% of the existing red rust was reduced to black rust by the NMR Pipe Protector. This confirmed the effectiveness of red rust prevention. The black rust formed by the NMR Pipe Protector acts to protect iron from red rust corrosion, and furthermore, black rust is a solid and dense crystal that is 1/10 the volume of red rust, thereby strengthening the pipe's durability. Thanks to the rust prevention effect of the NMR Pipe Protector, the air conditioning hot water pipes at City, University of London can now be used for over 40 years. *For more details, please refer to the PDF document or feel free to contact us.

The NMR Pipe Protector is adopted not only in Japan but also in various important facilities around the world. At the Mandarin Oriental Hyde Park in London, galvanized steel pipes (SGP) were used for the hot water supply. Galvanized steel pipes have a short lifespan of about 10 to 20 years, and red rust was occurring within the hotel's hot water supply pipes, resulting in poor water hygiene. While the standard value for iron content in water based on the UK's water quality regulations is 0.2 mg/l, the iron content in the hotel's hot water supply pipes was 13.35 mg/l. This value significantly exceeds the standard, highlighting the seriousness of the situation. With the NMR Pipe Protector, the iron content in the hot water supply pipes was reduced to below 0.2 mg/l. The NMR Pipe Protector utilizes free electrons in water, known as hydration electrons, to reduce the red rust that forms inside the pipes to black rust. This rust prevention technology, which Japan takes pride in, is also featured as one of the top 10 rust prevention technologies in the U.S. manufacturing technology magazine "Manufacturing Technology Insights" (March 12, 2020). *For more details, please refer to the PDF document or feel free to contact us.

This property is 14 years old, and there has been significant red rust blockage at the joints of the dissimilar metal connections in the hot water supply pipes. To prevent future piping rehabilitation and renewal work, we adopted the "NMR Pipe Protector," which costs less than one-tenth of that, before the red rust blockage progressed any further. When measuring the red rust blockage rate at the first joint of the hot water supply piping for the circulation pump, it was 12.4% before the installation of our product, but it decreased by 57.3% to 5.3% four months after installation. 【Introduction Overview】 ■ Building Name: GSK Building ■ Location: Shibuya, Tokyo ■ Building Overview: 14 years old, office building ■ Water Supply Method: Circulating hot water supply method ■ Installation Date: September 22, 2003 ■ Installed Piping/Number of Installations: Hot water supply piping on the secondary side of the storage tank (HTLP 65mm)/PT-75DS×1 unit *For more details, please refer to the PDF document or feel free to contact us.

At that time, the facility had been in operation for 42 years, and there were significant concerns about the corrosion of the hot water supply piping, which led to the adoption of the "NMR Pipe Protector." Before the installation of this product, the amount of black rust in the piping was 0.9%, but after 6 months of actual operation following installation, it increased to 16.9%, a relative increase of 1877.7%. The reduction of red rust to magnetite (black rust) has been demonstrated. In the future, if all the red rust turns into black rust, the piping will not require replacement as long as external corrosion does not occur. 【Introduction Overview】 ■ Location: Shibuya, Tokyo ■ Building Overview: 42 years old, 9-story office building ■ Installation Date: January 27, 2016 ■ Installed Piping: Cooling water pump primary side hot water supply piping (SGP pipe 200mm) ■ Number of Installations: PT-200DS × 1 unit *For more details, please refer to the PDF document or feel free to contact us.

This property has been in existence for 37 years, and due to the use of SGP (galvanized steel pipes) for the water supply pipes, there has been an occurrence of red water. Additionally, updating the piping requires a huge cost, and the necessary water outage work during the piping update could not be carried out due to business operations within the building, making it impossible to repair the piping. Therefore, we adopted the "NMR Pipe Protector," which prevents the occurrence of red rust in the pipes by converting it to black rust without allowing red rust to leak out, thus extending the life of the piping. Two months after installation, the complete leaching of red rust stopped, and three months after installation, an analysis of the black rust mass in the piping showed that 63.5% of black rust was confirmed. [Introduction Overview] ■ Before installation: The iron ion concentration in the water inside the pipes was 2.2 mg/l, with a color degree of 50. ■ Effects after installation: - Two months after installation, the complete leaching of red rust stopped. - Three months after installation, an analysis of the black rust mass in the piping confirmed 63.5% black rust. - Even after 20 years, the water supply piping continues to be used without any red rust issues. *For more details, please refer to the PDF document or feel free to contact us.
