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

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.

[NMR Pipe Protector Verification Results] Cambridge University Hospital

Completely prevent new red rust inside the piping! A case where it became possible to use until the building's lifespan by preventing external corrosion!

The hot water supply piping at the Cambridge University Hospital uses galvanized steel pipes (SGP) as the piping material, and the piping was updated three years ago. However, due to bacterial corrosion, red water and leaks occurred. To prevent red rust corrosion in this piping, "NMR Pipe Protectors" were installed. Before the installation of this product, the iron content in the hot water supply piping was high at 1.07 mg/l, and discoloration was observed. However, 11 days after installation, the iron content in the hot water decreased to 0.188 mg/l, and the red water was completely resolved. [Introduction Overview] ■ Hospital Name: Cambridge University Hospital (Addenbrooke's) ■ Hospital Location: Hills Road, Cambridge, UK ■ Hospital Overview: 28 years old (3 years since piping update), 5 stories (over 1000 beds) ■ Installation Date: February 16, 2004 ■ Installed Piping/Number of Units - Secondary hot water supply piping from the storage tank (SGP pipe 65mm) / PT-75DS x 2 units - Water supply piping for the 3rd floor system (SGP pipe 32mm) / PT-30DS x 1 unit *For more details, please refer to the PDF document or feel free to contact us.

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.
