Place of installation

For apartment domestic tap water systems

We install NMR Pipetector on the outlet pipe of a water pump or an elevated tank.

For-domestic-water-pipes-in-apartments

A suitable place for the installation varies by system and building structure. Shown below is a selection of typical installation examples.

For heating and chilled water systems

We install NMR Pipetector on the outlet pipe of a water pump. If a system has more than one water line, NMR Pipetector is installed on the pipe that entirely covers the water pipe.

For-circulating-air-conditioning-heating-or-chilled-water-systems

For condenser water systems

We install NMR Pipetector on the outlet pipe of a water pump.

For circulating, condenser water systems

For circulating domestic hot water systems

We install NMR Pipetector on the outlet pipe of a water pump. If there is more than one water line, NMR Pipetector is installed on the pipe where the entire water flows within.

For central domestic hot water pipes with boiler or hot water tank (or both)

*Once water passes through a pipe fitted with NMR Pipetector, the water molecules keep their treated condition for around six hours. This is why we need to install one NMR Pipetector per apparatus, such as an elevated tank where a large amount of water accumulates for six hours and more.

*NMR Pipetector is basically suitable on pipes where water flows at a velocity fewer than two meters per second for maximum efficiency. For steel pipes where water runs faster than this, we install two NMR Pipetector in series. It also needs at least a 130 mm-straight pipe for actual installation works.

Notable advantages

Reason1:Various case studies

Our history

Since our foundation in 1988, we have been handling NMR Pipetector as our main product for over 25 years. Thanks to the long-term support from our customers, we can keep our business growing. We strive to satisfy our customers even more, and that is why we can propose our products with confidence.

Adopted at more than 4,200 buildings

The number of successful installations we achieve is increasing every year. As of March 2020, the sum gratefully exceeded 4,200. Of the total, about 3,000 are apartments.

NMR Pipetector can be installed at any buildings, such as hospitals, hotels, universities, museums, department stores and various factories. There are five major piping systems NMR Pipetector is suitable: water mains, central heating and chilled, condenser, domestic tap, and hot water steel pipework.

Client testimonials

NMR Pipetector is highly evaluated for its safeness and rust-preventing effect. It is introduced to many iconic buildings not only in Japan but also in overseas nations.

We received client testimonials from four buildings as shown above: the Royal Bank of Scotland, which highly evaluated NMR Pipetector’s rust-preventing effect a year after the installation, the Guildhall in Central London, Whittington Hospital managed by Whittington Health NHS Trust, and a five-star hotel the Royal Garden Hotel London.

Reason2:Cost-effectiveness

Absolutely cheaper than the replacement of steel pipes
NMR Pipetector costs 1/5 to 1/10 than pipe replacement does
*Compared with replacement cost of domestic cold-water piping in apartments

Replacement of steel pipes costs between 6 and 10 thousand US$ per family in an apartment. On the other hand, NMR Pipetector costs 1/5 to 1/10 than the replacement. In other words, the device can reduce costs by 80 to 90%.

Avoid unnecessary risks when shutting off the water supply
No water outage

We ought to shut off the water supply to implement a replacement of steel piping, which costs a large amount of money. We need to suspend facility operation as the water supply has to be ceased during such works. This also leads to a large financial loss. It can be very profitable especially to hotels and hospitals by avoiding those works.

When it comes to NMR Pipetector, there is no need to do so. With the device, residents at apartments and condos do not need to line up every day for a portable bathroom during the replacement.

Zero maintenance and operation costs!
Zero-maintenance and operation costs!

NMR Pipetector does not use any power supply, consumable parts or chemical drugs, so there is no operation cost whatsoever. Also, the product itself is maintenance-free throughout its minimum life expectancy of 40 years, which leads to a significant reduction of labor and cost.

Achieving greater building asset
Contributes to increase asset value of buildings

With NMR Pipetector, buildings can save their budget for the maintenance of steel pipes. For example, an apartment can use a budget leeway to increase its asset value. Some of our customers actually used their extra budget to paint their exterior walls, waterproof their roofs, and even install an elevator.

Actual acievements

NMR Pipetector had a tremendous effect on improving a long-term refurbishment plan at an apartment in Japan.

Reason3:Outstanding features

Reason03
Total solution for red rust corrosion in steel pipes
NMR Pipetector solves problem

Red rust adheres to the inner surface of steel pipes as the years pass by.
Red rust dissolves in water and has the chemical property of making iron corrode and crumble. This leads to several issues, such as water discoloration, clogging, water leak and pipe joint break.

Reduces red rust to black rust

With free electrons of water, hydrated electrons, NMR Pipetector converts internal red rust to another substance called black rust.

What is black rust?
Chemical properties of black rust
what is black rust

Black rust does not dissolve in water and has an octahedral solid crystal structure,
whose cubic volume is less than 1/10 than that of red rust. Black rust is used as a protective coating on the surface of iron products, such as woks and steel locomotives. Black rust forms a hard layer on the surface of iron products and protects them from rusting for years.

By converting red rust to black rust, NMR Pipetector reduces iron content in water and stops water discoloration. NMR Pipetector’s rust prevention effect sustains for more than 40 years with a daily water consumption at 200 ~ 300 liters per water tap. In short, NMR Pipetector can keep your steel pipe available for as long as the life expectancy of your building.

Difference between steel pipe rinsing and NMR Pipetector
Difference between pipe rinsing and NMR Pipetector

As for steel pipe rinsing, a conventional and major method to address red rust, pipes are damaged and deteriorated when red rust is removed from within. Quite the opposite, NMR Pipetector improves red rust clogging inside steel pipes while strengthening pipes themselves by reducing red rust to black, not damaging the inner surface.

Extends lifespan of steel pipes to that of building
Can be used together for more than 40 years

If each room has a daily water consumption at about 200 ~ 300 liters per day, NMR Pipetector’s effectiveness will last for more than 40 years. It means that the lifespan of your steel pipes is extended as long as that of the building’s. There are many cases where piping’s life expectancy actually extended for more than 40 ~ 50 years with NMR Pipetector.

Case studies where steel pipes are used for over 50 years *As of 2021
  • Steel water supply piping at a major DPE plant in Tokyo: 56 years
  • Cold and hot steel water piping at Teigeki Building in Tokyo: 55 years
  • Air-conditioning hot and cold steel water pipes in the Yaesu-guchi Kaikan building in Tokyo: 56 years
Eliminates sliminess caused by bacteria

Steel pipe rinsing requires repeated cleaning once every 3 to 4 years to prevent bacteria from reoccurring. However, this hastens the steel pipe deterioration as the cleaning wears off pipe thickness. NMR Pipetector can permanently eliminate single-cell bacteria just by installing it on the outer surface of a pipe.

Product structure
How NMR Pipetector works
Chemical reaction in steel water pipes

Red rust occurs in steel pipes when they are oxidized with water and oxygen. This process can be expressed in a chemical formula as 4FeO + 3O2 + 2H2O → 4FeO (OH). At this time, iron is deprived of electrons through the oxidation process. In other words, iron oxidation stops when electrons are given to iron. With this reaction, NMR Pipetector reduces red rust to black rust by supplying hydrated electrons to red rust. This reaction is 6FeO (OH) + 2e → 2Fe3O4 + 2H2O + 2OH.

~Chemical reaction in water pipes~
Hydrated electrons located inside general water molecules

Water is an aggregation of water molecules (H2O). These aggregations are called water clusters, which contain hydrated electrons.

Hydrated Electrons are Located inside Normal Water Molecules
Using hydrated electrons

NMR Pipetector generates certain electromagnetic waves that relocate hydrated electrons inside normal water clusters to their outer surface. The detail is this: when the specific electromagnetic waves are emitted to water molecules, their nuclei, which are polarized to the North and South poles like magnets, start to resonate and cause a rotation. This phenomenon is called nuclear magnetic resonance (NMR). With the NMR phenomenon and water flow in steel pipes, hydrated electrons are emitted throughout piping from the outer surface of smaller water clusters.

*Required time varies, depending on conditions. Please contact us for detailed information.

Three ways to measure effectiveness

Select the most appropriate method for measuring the effect depending on the property type and piping system. We propose one of the three main measurement methods: filter, water sampling, and extraction of steel piping.

Example case study of water sampling
An example case of water sampling

Before installation, the level of iron content was 5.1 ㎎/ℓ in the steel water pipe, but after 3 weeks, it dropped to below 0.03 ㎎/ℓ.

An example case of filtering
An example case of filtering

Before installation, the level of iron content was 7.0 ㎎/ℓ after 14-day filtering. After a month, the level was reduced to 0.61 ㎎/ℓ tested under the same conditions as before.

An example case of cutting steel pipe
Sampled rust had a black rust ratio at only 4% before installation. However, after 9 months, the ratio soared to 43.6%. *A trial test at a major automobile factory
