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.

As a result of verifying the red rust prevention device "NMR Pipe Protector" in the hot water supply piping, a significant cost reduction was achieved, lowering the piping renewal costs to 1/50.

The Royal Garden Hotel London is beloved by travelers from around the world as one of the 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 rust corrosion had advanced, resulting in relatively dark red water emerging every morning when the tap was turned on. To address this, three "NMR Pipe Protectors" were installed on the main hot water supply pipe in the boiler room. Before installation, two weeks after installation, and then monthly for 12 months, water quality tests were conducted to measure the iron content in the water due to rust. As a result, it was found that the iron content in the water within the pipes had significantly decreased immediately after installation. Since the effectiveness of rust prevention was quantitatively proven, the hotel also installed NMR Pipe Protectors in the air conditioning pipes. Ultimately, while the cost of pipe renewal 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 original estimate. In terms of cost-effectiveness, it far exceeded the hotel's expectations. *Customer feedback (customer testimonials) and other PDF materials are available 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, London, galvanized steel pipes (SGP) were used for the hot water supply. Galvanized steel pipes have a relatively short lifespan of about 10 to 20 years, and red rust was occurring within the hotel's hot water supply pipes, leading to poor water hygiene. While the standard value for iron content in water based on UK 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 US 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 pipe 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 inside 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. Simultaneously, this red rust flows into copper fan coils, causing further blockage and reducing the effectiveness of heating and cooling. Additionally, the accumulation of red rust within the heat source equipment shortens the lifespan of the device. As the red rust deterioration progresses within the piping, the threads at the joints can break off, leading to water leaks during strong earthquakes. Since air conditioning chilled and hot water systems are centralized, updating the piping requires hotels and inns to halt operations for more than six months. The cost of piping replacement can also be substantial, ranging from hundreds of millions to over a billion yen, and the damages incurred from the business suspension are significant. Therefore, there has been a demand for the development of technology that can extend the life of air conditioning piping without the need for replacement.

It has also been adopted by Christ's College, Cambridge University!

It has also been adopted by Christ's College, Cambridge University!

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

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 plagued by issues related to red rust, and although sacrificial anodes were introduced in 2008 as a countermeasure, the progression of red rust did not stop. Additionally, while a rust inhibitor was administered annually, there was no change in the iron content of the water before and after its use, and concerns were raised about the potential effects of the rust inhibitor on human health. Therefore, to remove red rust and single-celled bacteria and to maintain 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, decreased to 17.95 mg/l three weeks after installation. As October arrived and the air conditioning hot water system operated at full capacity, the iron content 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.

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

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

Confirmed the rust prevention effect of the NMR pipe protector within the conditions of its effectiveness in the area of the piping.

To demonstrate the rust prevention effect of the NMR pipe protector, it is a condition that a certain amount of water flows within 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 used this water, resulting in a total water usage of 1 ton per day (with an average usage of 350 liters 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.

[Verification Results] Christ's College, University of Cambridge

Red rust is reduced to a strong passive black rust! A proven case of protection and extension of life within piping.

The university's air conditioning hot water piping has been troubled by internal red rust issues. 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, 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. [Issues] ■ The progression of red rust did not stop despite the introduction of a sacrificial anode. ■ Although a rust inhibitor was administered once a year, there was no change in the iron content in the water before and after its use, and concerns were raised 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)

[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. Therefore, on March 23, 2018, an "NMR Pipe Protector" was installed in the air conditioning hot water piping. One year after installation, a follow-up survey conducted by the bank revealed that the iron concentration was 0.03 mg/l, indicating a very low level and 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, thereby protecting the piping and extending its lifespan to match that of the building. [Effects After Installation] - Six weeks after installation, the iron concentration 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 concentration was 0.03 mg/l, indicating a very low level. - 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.*

Piping rust prevention, hospital water supply and air conditioning piping longevity device "NMR Pipe Protector"

Piping rust prevention, hospital water supply and air conditioning piping longevity device "NMR Pipe Protector"

NMR Pipe Protector extends the lifespan of hospital water supply pipes and air conditioning chilled and hot water pipes affected by red rust deterioration for over 40 years at one-tenth the cost of pipe replacement.

Water supply pipes and chilled/hot water piping generally require replacement due to aging deterioration. After 25 years, the chilled/hot water piping in hospitals can experience red rust deterioration, leading to blockages caused by red rust, which can then flow into copper fan coils and cause blockages, resulting in poor heating and cooling efficiency. Additionally, this red rust can accumulate within the heat source equipment, shortening its lifespan. In water supply pipes, red rust can develop at the joints, and as red rust deterioration progresses within both pipes, the threads at the joints can break off, leading to leaks during strong earthquakes. The NMR Pipe Protector prevents red rust deterioration, transforms red rust into black rust to improve pipe strength, and extends the lifespan of the piping. Since chilled/hot water is supplied through a central system, replacing the piping would require the hospital to halt operations for over six months, with replacement costs amounting to hundreds of millions to over a billion yen. The damages incurred from operational downtime are also significant, leading to a demand for technology that can extend the lifespan of air conditioning piping without replacement. The NMR Pipe Protector, a device for preventing red rust within pipes, has made this possible at less than one-tenth of the cost.

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (1)

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (1)

The Yokohama City Waterworks Bureau has verified the effectiveness of the NMR pipe protector in preventing red rust and reducing chlorine for disinfection in the water supply pipes at the Tsurumi public housing.

At the Yokohama City Waterworks Bureau, a demonstration test was conducted at the 20-year-old Tsurumi water reservoir's attached public housing to prevent the formation of red rust in the water supply pipes, thereby addressing the issue of reduced chlorine concentration in the water due to red rust. The test utilized the water supply pipe from the vacant bathroom of Room 102. The piping materials used included polyethylene-lined steel pipes in the shared areas and resin pipes in the exclusive areas, where red rust had formed at the pipe joint sections. Before the installation of the NMR pipe protector, the iron concentration in the stagnant water of the bathtub's water supply valve at night was 0.27 mg/L, with a residual chlorine level of 0.11 ppm at that time. Additionally, over the two weeks prior to installation (with water flowing for 3 hours each day), the amount of red rust accumulated on the faucet filter was 13 mg/L, indicating significant corrosion of red rust at the pipe joint sections.
