Pipe anti-corrosion, the Royal Garden Hotel in the UK has introduced NMR pipe protectors.

Pipe anti-corrosion, the Royal Garden Hotel in the UK has introduced NMR pipe protectors.

The results of verifying the red rust prevention device "NMR Pipe Protector" for hot water supply piping showed a significant cost reduction in piping renewal expenses to 1/50.

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.

NMR Pipe Protector that Promotes the Growth of Tomatoes and Strawberries in Agriculture

NMR Pipe Protector that Promotes the Growth of Tomatoes and Strawberries in Agriculture

The rust prevention effect of the NMR pipe protector is due to the action of small clusters of water, which has also been proven to promote the growth of tomatoes and strawberries.

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.

Pipe anti-corrosion, Mandarin Oriental Hotel introduces NMR pipe protector.

Pipe anti-corrosion, Mandarin Oriental Hotel introduces NMR pipe protector.

Significant cost reduction in hot water pipes at a 5-star hotel with red rust prevention device "NMR Pipe Protector"

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.

Hotel and inn air conditioning piping is protected from red rust and leaks by NMR pipe protectors.

Hotel and inn air conditioning piping is protected from red rust and leaks by NMR pipe protectors.

Extend the lifespan of hotel and inn air conditioning piping affected by red rust deterioration for over 30 years at one-tenth the cost of piping replacement.

"Red Rust Deterioration of Air Conditioning Chilled and Hot Water Piping" Air conditioning chilled and hot water piping that has been in use for over 25 years experiences the loss of the zinc coating on the inner surface of the steel pipes within 4 to 5 years. As the surface of the iron comes into contact with water, red rust deterioration occurs, leading to red rust blockage. At the same time, this red rust flows into copper fan coils, causing further blockage and reducing the efficiency of heating and cooling. Additionally, the accumulation of red rust within the heat source equipment shortens its lifespan. As the red rust deterioration progresses within the piping, the threads at the joints may break off, leading to water leaks during strong earthquakes. Since the air conditioning chilled and hot water system is centralized, updating the piping requires hotels and inns to suspend operations for more than six months, and the cost of piping replacement can be several hundred million to over a billion yen. The damages incurred from the suspension of operations are also significant, leading to a demand for the development of technologies that can extend the life of air conditioning piping without replacement.

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (2)

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (2)

The Yokohama City Waterworks Bureau has verified the effectiveness of the "NMR Pipe Protector" in preventing the decrease of residual chlorine concentration in water distribution pipes.

The Yokohama City Waterworks Bureau confirmed an increase in residual chlorine concentration to prevent red rust and the associated reduction of disinfectant chlorine in the water supply pipe at the Tsurumi public office. Therefore, starting from November 5, 2012, a demonstration test was conducted using the water distribution pipe (100A) in the Hazawa area to prevent the decrease in residual chlorine concentration. During six measurements conducted from September 26 to October 30, before the installation of the NMR pipe protector, the residual chlorine concentration at the planned installation site (Point A) averaged 0.55 mg/L (with Point A's residual chlorine concentration set at 100%), while 50 meters downstream (Point B) averaged 0.41 mg/L (a reduction rate of 25.45%), and at the farthest point, 125 meters away (Point C), it averaged 0.23 mg/L (a reduction rate of 58.18%), indicating a decrease due to the red rust occurring in the piping. Subsequently, on November 5, the NMR pipe protector was installed, and after more than three months, during three measurements from February 19 to March 22, the residual chlorine concentration at the installation site (Point A) averaged 0.61 mg/L, while at 50 meters downstream (Point B) the average for the same three measurements was 0.61 mg/L (a reduction rate of 0%), showing that the decrease was mostly prevented. Even at the farthest point, 125 meters away (Point C), the average for the same three measurements was 0.55 mg/L (a reduction rate of 9.84%), significantly improving the reduction rate.

Extend the lifespan of piping! Case study of the "NMR Pipe Protector" introduced at Christ's College, Cambridge University.

Christ's College, Cambridge University, originated from God's House, which was established in 1437, and was rebuilt and opened as Christ's College in 1505 at nearly the same location. It is also famous for producing numerous notable alumni, including Charles Darwin, the author of "On the Origin of Species." The university's air conditioning hot water piping has been troubled by issues related to red rust internally, and although sacrificial anodes were introduced in 2008 as a countermeasure, the progression of red rust did not stop. Additionally, an anti-corrosion agent was applied annually, but there was no change in the iron content of the water before and after its use, raising concerns about the agent's impact on human health. Therefore, to remove red rust and single-celled bacteria while maintaining the strength of the piping, an NMR pipe protector was installed on July 31, 2013, in the air conditioning hot water piping (return pipe) of the Todd Building on the university campus. The iron content in the water, which was 43.81 mg/l before installation, dropped to 17.95 mg/l three weeks after installation. As October arrived and the air conditioning hot water system operated at full capacity, the levels continued to decrease, reaching 0.5195 mg/l by August 5, 2014, 52 weeks after installation, which is about one-eighty of the original level.

Verification of the effectiveness of NMR pipe protectors by the Yokohama City Waterworks Bureau.

Verification of the effectiveness of NMR pipe protectors by the Yokohama City Waterworks Bureau.

Confirmed the rust prevention effect inside the piping in areas where the NMR pipe protector's rust prevention effect conditions are met.

To demonstrate the rust prevention effect of the NMR pipe protector, a certain amount of water must flow through the piping. In the Konan Chuo area where the rust prevention effect test was conducted, the minimum water usage for a 50A pipe was 4.4 tons per day, but only three households were using that water, resulting in a total water usage of 1 ton per day (an average of 350 liters per day per household), which is very low. In the Teramachi 2-chome area, the number of households using water for each branched pipe with a diameter of 50A was six and eight, respectively, with the six households using about 2 tons of water per day and the eight households having a total water usage of just under 3 tons per day. Due to insufficient water usage, a clear rust prevention effect could not be confirmed. However, in the Tsurumi Public Housing and Hazawa area, where similar verification tests were conducted, the conditions were met. In Tsurumi Public Housing, the red rust in the water supply pipe decreased from 0.27 mg/l to 0.12 mg/l six weeks after the installation of the NMR pipe protector, and an increase in residual chlorine concentration, which had been reduced due to red rust, was confirmed. In the Hazawa area, the residual chlorine concentration, which had decreased by 45.3%, improved significantly to a reduction of 13.6%. The Yokohama City Waterworks Bureau has concluded the tests as there are no more suitable locations to further test the rust prevention effect of the NMR pipe protector.

Red rust is reduced to a strong passive black rust! A proven case of protection and prolongation of pipes.

The university's air conditioning hot water piping has been plagued by issues related to internal red rust, and although a sacrificial anode was introduced in 2008 as a countermeasure, the progression of red rust did not stop. Additionally, a rust inhibitor was administered once a year, but there was no change in the iron content in the water before and after the use of the rust inhibitor, raising concerns about its effects on human health. Therefore, in order to remove red rust and single-celled bacteria while maintaining the strength of the piping, an "NMR Pipe Protector PT-75DS" was installed in the air conditioning hot water piping (return pipe) of the Todd Building on campus. The iron content in the water, which was 43.81 mg/l before installation, decreased to 17.95 mg/l three weeks after installation. [Challenges] ■ Although a sacrificial anode was introduced, the progression of red rust did not stop. ■ A rust inhibitor was administered once a year, but there was no change in the iron content in the water before and after its use, and there were concerns about its effects on human health. *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Royal Bank of Scotland (RBS)

The anti-corrosion effect inside the piping lasts for one year! By protecting the inside of the piping, the lifespan of the piping is extended to match the lifespan of the building.

The 250th branch, located in the Bishops Gate area of London, which was built 18 years ago, had issues with red rust deterioration in its air conditioning system. To address the red rust in the piping, a rust inhibitor was being used, but there were environmental concerns. On March 23, 2018, "NMR Pipe Protector" was installed in the air conditioning hot water piping. One year after installation, the bank conducted its own follow-up survey, which showed that the iron content was at a very low level of 0.03 mg/l, confirming that the rust prevention effect in the piping persisted after one year. Furthermore, it was demonstrated that by continuing to use this product in the future, red rust would be reduced to a stable black rust, protecting the piping and extending its lifespan to match that of the building. [Effects After Installation] - Six weeks after installation, the iron content in the water was measured under the same conditions as before installation, showing a decrease from 1.1 mg/l to 0.41 mg/l. - One year after installation, the iron content was at a very low level of 0.03 mg/l. - It was demonstrated that protecting the piping would extend its lifespan to match that of the building. *For more details, please refer to the PDF document or feel free to contact us.
