At Hospital #H, which was built 48 years ago, the air conditioning chilled and warm water piping using galvanized steel pipes (SGP) has experienced significant deterioration due to red rust, leading to leaks. Therefore, a red rust prevention piping extension device, the "NMR Pipe Protector," was installed. Before installation, a sample of the circulating chilled and warm water was taken, revealing a total iron concentration of 2.5 mg/l, indicating that red rust corrosion was progressing within the piping. Four weeks after the installation of the product, a subsequent water sample showed a significant reduction in total iron concentration to 0.4 mg/l. A water sample taken six years after installation showed an even further reduction to 0.2 mg/l, confirming that the progression of new red rust within the chilled water piping had completely stopped. The existing red rust had transformed into an insoluble, passive black rust with a volume reduced to one-tenth.

This nursing facility had experienced significant deterioration due to red rust in the water supply and hot water supply pipes. Therefore, when the building was 25 years old, a red rust prevention device called the "NMR Pipe Protector" was installed in the water supply pipe on the secondary side of the rooftop water tank and in the hot water supply pipe on the secondary side of the boiler. Before the installation of the NMR Pipe Protector, the iron ion concentration in the water supply was 2.27 mg/l, and the color degree was 20, indicating severe deterioration due to red rust in the pipes. Four weeks after the installation of the NMR Pipe Protector, the iron ion concentration in the water dropped to 0.46 mg/l, and the color degree improved to 5, showing a significant improvement in water quality. Furthermore, the water quality test results 12 weeks after installation showed that the iron ion concentration was 0.03 mg/l, and the color degree was less than 0.5. The red rust in the water supply pipe had transformed into hard crystalline black rust with a volume reduction of 1/10, stopping the leaching of red rust into the water. The rehabilitation of the pipes due to the black rust formation was confirmed. This demonstrated that if the use of the NMR Pipe Protector continues, both the water supply and hot water supply pipes can be extended to the lifespan of the building.

The hospital had been built for 27 years at the time, and the air conditioning chilled and warm water piping, which used galvanized steel pipes (SGP), was experiencing significant deterioration due to red rust, raising concerns about leaks. Before the red rust corrosion could progress any further, a red rust prevention piping extension device called "NMR Pipe Protector" was installed. After 52 days of installation, under the same conditions, the water sampled from the air conditioning warm water showed a transparent color, and the water quality test results indicated that the iron ion concentration in the water was 0.27 mg/l, which is below the water quality standard value (1.0 mg/l) set by the Japan Refrigeration and Air Conditioning Industry Association. If this product continues to be installed in the hospital's air conditioning chilled and warm water piping, it has been verified that the red rust deterioration and leaks in the piping will be completely prevented, extending the piping's lifespan to that of the building.

【Effects After Installation】 ■ Prevention of damage to the impeller of the cooling water pump due to calcium crystals ■ Prevention of calcium scale solidification and adhesion inside the pump ■ Reduction of line stoppage frequency from 1.2 times per month due to pump disassembly and cleaning, leading to increased productivity! Our factory was experiencing a situation where the line stopped every month (20 times/year) due to strong calcium scale adhering inside the pump, causing internal damage and requiring disassembly and cleaning. After the installation of the "Non-Scaler," there have been no line stoppages for over six months. Upon checking the scale condition inside the pump casing, it was found to be soft and in fine particle form, rather than forming strong calcium scale. By preventing damage to the pump caused by calcium scale, we have not only avoided line stoppages but also achieved significant reductions in maintenance costs. *For more details, please refer to the PDF document or feel free to contact us.

The cooling water used in open-type central air conditioning cooling towers has its calcium concentration rise to about 7 to 10 times that of the make-up water (source water) due to evaporation, resulting in the formation of hard calcium carbonate crystals on the surface of the cooling fins outside the cooling tower, which reduces cooling efficiency. The non-scaler, when installed in the make-up water piping, transforms dissolved calcium hydroxide in the water into calcium carbonate nanoparticles, dispersing them in the water and preventing calcium from solidifying and adhering to the cooling fins of the cooling tower. *For more details, please refer to the PDF document or feel free to contact us.*

The heat exchanger at the chemical plant was subject to calcium scale buildup, necessitating disassembly, cleaning, and washing every five months. When scale accumulated on the heat exchanger, it reduced cooling efficiency and negatively impacted product quality. After installing a "non-scaler" following the cleaning of the heat exchanger, there was no calcium carbonate buildup on the hot water piping even after five months, resulting in maximum cooling effectiveness of the cooling water and maintaining the lowest defect rate for products. Additionally, the need to stop the plant every five months to scrape off calcium carbonate from the outside of the hot water piping was eliminated, leading to a reduction in product defect rates and an improvement in productivity. *For more details, please refer to the PDF document or feel free to contact us.*

Nineteen years after the installation of the NMR pipe protector, an inspection was conducted by the condominium management association of a 9-story, 110-unit building in Sapporo, Hokkaido, when the building was 32 years old. They commissioned an external investigation company to examine the condition of red rust deterioration at the water supply pipe joints. Ten locations were selected within the pipe space of the water supply pipes (pipe diameters 25A to 65A) from the 1st to the 9th floor, and a non-destructive inspection using X-rays was performed on the joint areas. The results of the X-ray inspection showed that out of the ten locations, eight had no signs of red rust deterioration at the pipe joints. The other two locations showed only slight traces of corrosion, which were estimated to have occurred before the installation of the NMR pipe protector. This demonstrated that the red rust deterioration of the water supply pipes in this condominium had been completely prevented. Although the NMR pipe protector cannot prevent corrosion on the outside of the pipes, slight external corrosion was observed. However, by preventing external corrosion with anti-rust coatings, both the exterior and interior can be preserved. *Images and inspection results are quoted from a report by a certain industrial inspection agency.

A follow-up survey was conducted in a condominium in Fukuoka Prefecture, 16 years after the installation of the NMR pipe protector. Before installation, the joints of the water supply pipes in Rooms A and B were inspected with a fiberscope, revealing red rust blockage rates of 50.7% and 78.2%, respectively, indicating significant progression of red rust blockage and the need for early intervention. Consequently, the NMR pipe protector was installed in the water supply piping. One year after installation, a follow-up survey was conducted under the same conditions as before installation, and the red rust blockage rates for Rooms A and B were as follows: [One Year After Installation] Room A: 50.7% → 48% [5.3%] reduction improvement Room B: 78.2% → 74.1% [5.2%] reduction improvement [Sixteen Years After Installation] Room A: 50.7% → 41.2% [18.7%] reduction improvement Room B: 78.2% → 68.4% [12.5%] reduction improvement From the above reduction improvement rates in red rust blockage, it was demonstrated that the NMR pipe protector completely prevented the occurrence of new red rust and that the red rust blockage transformed into black rust with a volume reduction to one-tenth. Additionally, it was proven that as long as this condominium remains standing for another 20 or 30 years, pipe replacement will not be necessary.

At Hotel Serve Shibuya, galvanized steel pipes (SGP) are used for the air conditioning chilled and hot water piping, and there was a concern about the deterioration due to red rust and leakage from the joints. As a countermeasure against red rust deterioration and leakage, a red rust prevention pipe longevity device called "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, water samples were taken from the air conditioning chilled and hot water piping, revealing that the water was tinted light brown, with a total iron content of 5.8 mg/l, indicating significant red rust corrosion within the pipes. Two weeks after the installation of the NMR Pipe Protector, the total iron content in the water within the air conditioning chilled and hot water piping significantly decreased to 0.6 mg/l. In a water sample taken four weeks after the installation, the water was nearly transparent, with the total iron content further reduced to 0.5 mg/l. It was proven that new red rust was completely prevented within the air conditioning chilled and hot water piping, and the existing red rust had transformed into inert black rust. Going forward, if the use of the NMR Pipe Protector continues to prevent external corrosion at Hotel Serve Shibuya, all red rust in the air conditioning chilled and hot water piping will change to black rust, and it has been demonstrated that this piping can be extended to the lifespan of the building. Naturally, leakage has been completely prevented thereafter.

This property has been in existence for 30 years, and there has been significant red rust blockage at the water supply pipe joints. Therefore, the red rust prevention device "NMR Pipe Protector" was adopted. When measuring the red rust blockage in the water supply pipes of Room A and Room B, it was found that before the installation of the NMR Pipe Protector, Room A had a blockage rate of 43.2% and Room B had a rate of 50.9%. 【Red Rust Blockage Rate One Year After Installation】 Room A: 41.7% Room B: 50.6% 【Red Rust Blockage Rate Five Years After Installation】 Room A: 39.7% Room B: 49.8%, confirming a reduction improvement rate of 8.1% and 2.1% respectively compared to before installation. 【Red Rust Blockage Rate Ten Years After Installation】 Room A: decreased to 36.8% Room B: decreased to 37.5%, showing a significant reduction in red rust of 48% for Room A and 26.3% for Room B compared to before installation. From these results, it has been demonstrated that the installation of the NMR Pipe Protector has halted the progression of red rust deterioration in the pipes, and the existing red rust has been reduced to black rust with a volume of less than 1/10, proving the effectiveness of pipe rehabilitation and red rust prevention.

Moseley Hospital has two independent hot water systems: one connected to the storage tank and the other connected to the hot water header, with galvanized steel pipes used in the hot water piping. As a result, NMR pipe protectors were installed in the storage tank piping and the hot water header piping to prevent red rust corrosion and leaks in both hot water systems. Water samples were taken from the hot water piping at five locations, and the average iron content in the water was calculated. Before the installation of the NMR pipe protectors, the average value was 13.824 mg/l. After 15 weeks of installation, it decreased to 1.3882 mg/l; after 31 weeks, it further decreased to 0.4762 mg/l; and after 49 weeks, it reached 0.3428 mg/l, showing a significant reduction. This result demonstrated that the NMR pipe protectors prevented the formation of new red rust within the pipes and reduced existing red rust to black rust, which is insoluble in water and has a volume that is one-tenth of that of red rust. It has been proven that by continuing to install NMR pipe protectors, the hot water piping will transform 100% of the red rust within the pipes into black rust, thereby extending the lifespan of the building.

The hot water supply pipes used in Windsor Castle, owned by the British royal family and with a history of 900 years, utilize SGP pipes. To prevent red rust deterioration and extend the lifespan of the pipes, an NMR Pipe Protector was installed on January 24, 2007. Before the installation of the NMR Pipe Protector, the iron content in the water in Room 107 was 3.32 mg/l, but 42 days after installation, it dropped to 0.007 mg/l. Additionally, the average iron content from two other sampling locations was 4.255 mg/l before installation, but decreased to 0.0105 mg/l after installation. This is significantly lower than the drinking water quality standard set by the UK, which is 0.2 mg/l. As a result, it has been demonstrated that the NMR Pipe Protector effectively prevents the occurrence of new red rust within the pipes and transforms existing red rust into black rust, which does not dissolve in water. By continuing to use the NMR Pipe Protector, the hot water supply pipes have completely eliminated internal red rust deterioration and, by preventing external corrosion, have become usable for as long as the building remains standing.

Calcium scale inevitably adheres to the interior of hot water boilers and similar equipment. To reduce the adhesion of calcium scale, traditionally, ion exchange resins have been used to soften the water by removing calcium ions before producing hot water in the boiler. The residual calcium in the water crystallizes as insoluble calcium carbonate within the boiler and adheres to it. Traditionally, strong alkaline agents were added to the boiler to prevent the formation reaction of calcium carbonate. However, strong alkaline hot water is highly corrosive to metals, leading to corrosion and deterioration of the boiler itself, internal piping, and hot water piping, which shortens the lifespan of the boiler and connected piping systems to around 10 years. The calcium scale prevention device "Non-Scaler" reacts the calcium in the water with free carbon dioxide within the Non-Scaler, forcibly transforming it into fine particles of calcium carbonate that are dispersed and flow in the water. Once calcium carbonate is converted into fine particles, it remains unchanged even under the high temperature and pressure conditions inside the boiler, flowing in its particulate state. Additionally, the effects of corrosion and deterioration caused by strong alkaline agents are eliminated, making it possible to extend the lifespan of the boiler and hot water piping by more than double.

This property is 11 years old, and the red rust blockage at the joint of the water supply pipe in the exclusive area had progressed to about 70%. To prevent further progression of the red rust blockage and to avoid future piping renewal work, we adopted the NMR pipe protector, which costs less than one-tenth of that. As a result of an endoscopic investigation, the red rust blockage rate in the toilet water supply pipe at the first joint before the installation of the NMR pipe protector was 69.8%. Twelve months after the installation of the NMR pipe protector, the red rust blockage rate was reduced to 60.6%, showing an improvement of 13.2%. The significant improvement in red rust blockage due to the volume contraction associated with the transformation of red rust to black rust has been demonstrated, confirming the effectiveness of the piping rehabilitation due to the transformation of red rust to black rust.

This property is a 29-year-old building that originally used galvanized steel pipes (SGP) for its plumbing at the time of completion, but over the years, it has been updated to use vinyl-lined steel pipes (VLP). However, due to the building's structure, the plumbing inside the framework remained galvanized steel pipes (SGP), which led to the occurrence of red water due to corrosion. To address the red water issue in the water supply pipes and to protect and extend the life of the plumbing, NMR Pipe Protectors were installed. The NMR Pipe Protector costs less than one-tenth of traditional plumbing renovation work and can rehabilitate the pipes by converting red rust into black rust without allowing it to flow out. In water quality tests conducted before the installation of the NMR Pipe Protector, the iron ion concentration was 0.3 mg/l. However, about five weeks after the installation of the NMR Pipe Protector, this concentration dropped to 0.01 mg/l, which is one-thirtieth of the original level, effectively resolving the red water issue. Additionally, an endoscopic examination revealed that the rate of blockage due to red rust in the pipes improved by more than 10% after one year and three months. These results confirm that the rust prevention effect of the NMR Pipe Protector and the rehabilitation effect of converting red rust to black rust continue to be effective.

When a layer of red rust (with a thermal conductivity that is 1/180th that of copper) forms inside the air conditioning fan coil (made of copper), electricity costs can increase by more than 10%. The pipe protector converts red rust into black rust (with a thermal conductivity that is 16 times greater than that of red rust), which can reduce electricity costs by 10%. Using the NMR pipe protector allows you to immediately experience improved air conditioning efficiency. 〇 Examples of Red Rust Prevention in Air Conditioning Pipes Buckingham Palace in the UK, BBC, UK Parliament, Japanese Red Cross Hospital, famous hotels, well-known department stores, bookstores, and the Imperial Theatre building, among others. * You can download the materials for free. * Please feel free to contact us first.

1. Regarding the effectiveness of rust prevention (anti-corrosion) In the UK, coil-type electromagnetic devices are primarily used as a measure against calcium scale, and their effectiveness in preventing red rust has not been recognized. In fact, at St. Thomas' Hospital, famous for Florence Nightingale and where the NHS headquarters is located, this device was introduced into the hot water piping, but it showed no anti-corrosion effect, and red rust deterioration was progressing. As a result, an NMR pipe protector was installed in 2005. Before installation, the hot water contained a high concentration of iron ions, but after one month, the concentration significantly decreased, halting the progression of red rust deterioration and confirming a change to insoluble black rust. Although coil-type electromagnetic devices are also sold domestically, please be aware that their effectiveness against red rust has not been confirmed. 2. Regarding the effectiveness of calcium scale prevention Coil-type electromagnetic devices are also sold domestically as scale prevention devices, but in a major food factory where they were introduced, they failed to prevent scale adhesion within the pumps. As a result, a non-scaler was adopted, completely preventing adhesion. Disassembly and cleaning, which were previously required every few months, are no longer necessary. If you have not achieved results with coil-type devices, please consider introducing a non-scaler.
