The fourth reason why NMR Pipetector is chosen by our customers is its clear effectiveness.
The effectiveness is measured by a third-party testing organization in numeric figures in a short time.
Actual benefits of NMR Pipetector can be obtained within a month after it is installed.
NMR Pipetector is an ideal and quick solution for red rust-related problems, such as water discoloration and pipe cloggings.

We set the most appropriate method for test trials, depending on types of building and piping.
We mainly offer four methods: *endoscopy, filtering, water sampling and cutting pipe section.
*Endoscopy is done in Japan only
For appartments' cold-water pipes in Japan, we basically measure rates of clogging with an endoscopy in a bid to monitor the effectiveness. For domestic cold-water pipes in hospitals and hotels, we attach filters to a tap (faucet) for a certain period and measure iron contents captured in the filters to assess the effectiveness.
Before installation, the piping was clogged at 23.7%, but the rate dropped to 13.6 % after 12 months and further dropped to 9.2% after 43 months.
Before installation, level of iron content was 7.0 ㎎/ℓ after a 14-day filtering. After a month, the level was reduced to 0.61 ㎎/ℓ tested under the same conditions as before.
Pipes in which water circulates, such as air-conditioning heating and chilled water pipes, are collectively called circulating water systems. For such systems, we take water as samples from inside and measure iron contents in the samples to monitor the effectiveness. Since the NMR Pipetector reduces red rust to black rust, we cut pipe sections and take rust sample from inside and measure increased amount of black rust ratio to the total rust after installation in some cases.
Before installation, the level of iron content was 5.1 ㎎/ℓ in the water pipe, but after 3 weeks, it dropped to below 0.03 ㎎/ℓ.
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
*Iron contents were tested at Miyagiken Kogai Eisei Kensa Center (Hygiene and Environment Pollution Center in Miyagki Prefecture, Japan)
*Black rust ratio was tested at Material Science Technology Association
Our engineers carry out trial tests in the presence of customers, since no other organization besides ourselves can conduct accurate endoscopy measuring rates of clogging.
NMR Pipetector effectiveness was tested by Prof.
Yuta from Hokkaido University at Industrial Technology Research Facility in Hokkaido as a scientific proof.
In detail, level of iron content in water was 0.786 ㎎/ℓ before installation but was gradually reduced in a month after installation and was further reduced to 0.262 ㎎/ℓ after 4 months. The level is now less than that of the Japanese Drinking Water Safeness Act set at 0.3 ㎎/ℓ.
|Before installation||After 1 month||After 2 months||After 4 months||The Japanese Drinking Water Safeness Act|
|Iron content (㎎/ℓ)||0.786||0.553||0.423||0.262||<0.300|
*Sampled 500 cc of water at the earliest in the morning. The water was unused for consecutive 8 hours during the night.
