[NMR Pipe Protector Verification Results] BBC (British Broadcasting Corporation)

[NMR Pipe Protector Verification Results] BBC (British Broadcasting Corporation)

Verification of rust prevention effects in the air conditioning piping of the BBC (British Broadcasting Corporation)! Preventing the occurrence of new red rust and converting existing red rust to black rust, demonstrating the extension of piping lifespan.

After 53 years since its construction, the BBC (British Broadcasting Corporation) has been experiencing serious deterioration of its cooling water piping due to the use of SGP pipes, leading to frequent leaks and significant rust issues. To prevent leaks caused by rust deterioration and to extend the lifespan of the piping, four "NMR Pipe Protectors" were installed in the cooling water systems of the Main Block Building and Stage 5 Building. In the Main Block Building, the iron concentration in the water was 5.53 mg/l before the installation of the product, but it significantly decreased to 0.048 mg/l after 32 days and further reduced to 0.06 mg/l after 57 days. In Stage 5 Building, the iron concentration in the water was 3.8 mg/l before installation, which decreased to 0.063 mg/l after 32 days and to 0.008 mg/l after 57 days. Additionally, there have been no leaks reported after the installation. The prevention of new rust formation and the transformation of existing rust in the piping into insoluble black rust in the water have resulted in a reduction of iron concentration, demonstrating that this cooling water piping can be extended to the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.*

[Non-Scaler Introduction Case Study] Major Steelworks Factory

[Non-Scaler Introduction Case Study] Major Steelworks Factory

Preventing blade damage in the cooling water pump! A case study that reduced the frequency of line stoppages through pump disassembly and cleaning 1.2 times per month.

【Effects After Installation】 ■Prevention of damage to the impeller inside the cooling water pump due to calcium crystals ■Prevention of calcium scale solidification and adhesion inside the pump ■Reduction of line stoppage frequency from 1.2 times per month due to pump disassembly and cleaning, leading to increased productivity! Our factory was experiencing a situation where the line stopped every month (20 times/year) due to the strong adhesion of calcium scale inside the pump, resulting in internal damage and the need for disassembly and cleaning. After installing the "Non-Scaler," there have been no line stoppages for over six months. Upon checking the scale condition inside the pump casing, it was found to be soft and in fine particle form, rather than forming strong calcium scale. By preventing damage to the pump caused by calcium scale, we have not only avoided line stoppages but also achieved significant reductions in maintenance costs. *For more details, please refer to the PDF document or feel free to contact us.

Non-scaler introduction case: Cooling tower

Non-scaler introduction case: Cooling tower

A case of preventing the adhesion of calcium scale that adheres to the outer cooling fins of a cooling tower.

The cooling water used in open cooling towers for central air conditioning increases the calcium concentration in the water to about 7 to 10 times that of the make-up water (source water) due to evaporation, resulting in the formation of hard calcium carbonate crystals on the surface of the cooling fins outside the cooling tower, which reduces cooling efficiency. The non-scaler, when installed in the make-up water piping, transforms dissolved calcium hydroxide in the water into calcium carbonate nanoparticles, dispersing them in the water and preventing calcium from solidifying and adhering to the cooling fins of the cooling tower. *For more details, please refer to the PDF document or feel free to contact us.*

[NMR Pipe Protector] Effectiveness Demonstrated through X-ray Inspection | Hokkaido Condominium

[NMR Pipe Protector] Effectiveness Demonstrated through X-ray Inspection | Hokkaido Condominium

Effectiveness demonstrated by X-ray inspection of the condominium water supply pipe 19 years after the installation of the NMR pipe protector.

Nineteen years after the installation of the NMR pipe protector, in a condominium in Sapporo, Hokkaido (a 9-story building with 110 units) that was 32 years old, the condominium management association commissioned an external investigation company to conduct an inspection of the red rust deterioration state of the water supply pipe joints. Ten locations were selected within the water supply pipes (pipe diameters 25A to 65A) in the pipe space from the 1st to the 9th floor, and a non-destructive inspection of the red rust deterioration state of the joints was conducted using X-rays. As a result of the X-ray inspection, eight out of the ten locations showed no signs of red rust deterioration at the pipe joints. The other two locations had only slight traces of corrosion, which were estimated to have occurred before the installation of the NMR pipe protector. This demonstrated that the red rust deterioration of the water supply pipes in this condominium has been completely prevented. Although the NMR pipe protector cannot prevent corrosion on the outside of the pipes, slight external corrosion was observed. However, by preventing external corrosion with rust-proof paint and other measures, both the exterior and interior can be preserved. *Images and investigation results are quoted from a report by a certain industrial inspection agency.

[NMR Pipe Protector Verification Results] Windsor Castle

[NMR Pipe Protector Verification Results] Windsor Castle

Preventing red rust deterioration of the hot water piping at Windsor Castle in the UK!

The hot water supply pipes used in Windsor Castle, owned by the British royal family and with a history of 900 years, utilize SGP pipes. To prevent red rust deterioration and extend the lifespan of the pipes, an NMR Pipe Protector was installed on January 24, 2007. Before the installation of the NMR Pipe Protector, the iron content in the water in Room 107 was 3.32 mg/l, but 42 days after installation, it dropped to 0.007 mg/l. Additionally, the average iron content from two other sampling locations was 4.255 mg/l before installation, but decreased to 0.0105 mg/l after installation. This is significantly lower than the drinking water quality standard set by the UK, which is 0.2 mg/l. As a result, it has been demonstrated that the NMR Pipe Protector effectively prevents the occurrence of new red rust within the pipes and transforms existing red rust into black rust, which does not dissolve in water. By continuing to use the NMR Pipe Protector, the hot water supply pipes have completely eliminated internal red rust deterioration and, by preventing external corrosion, have become usable for as long as the building remains standing.

[NMR Pipe Protector Verification Results] Lions Mansion Koshigaya North

Proving rust prevention effects through a 10-year post-installation effectiveness evaluation!

This property has been in existence for 30 years, and the red rust blockage in the water supply pipe joints has progressed significantly. Therefore, the "NMR Pipe Protector," a device for preventing red rust in pipes, was adopted. When measuring the red rust blockage in the water supply pipes of Room A and Room B, it was found that before the installation of the NMR Pipe Protector, Room A had a blockage rate of 43.2% and Room B had a blockage rate of 50.9%. 【Red Rust Blockage Rate One Year After Installation】 Room A: 41.7% Room B: 50.6% 【Red Rust Blockage Rate Five Years After Installation】 Room A: 39.7% Room B: 49.8%, showing a reduction improvement rate of 8.1% and 2.1% compared to before installation, respectively. 【Red Rust Blockage Rate Ten Years After Installation】 Room A: decreased to 36.8% Room B: decreased to 37.5%, showing a significant reduction in red rust of 48% for Room A and 26.3% for Room B compared to before installation. From these results, it was confirmed that the installation of the NMR Pipe Protector halted the progression of red rust deterioration in the pipes, and the existing red rust was reduced to black rust with a volume of less than 1/10, demonstrating the effectiveness of pipe rehabilitation and red rust prevention.

Mechanism of scale measures

Mechanism of scale measures

The mechanism of scale removal and prevention by The Bio Water!

Scale refers to the phenomenon where calcium carbonate (CaCO3) or silicon dioxide (silica, SiO2) precipitates and adheres to pipes and water supply and heating equipment. We will introduce the reaction mechanism of scale detachment and prevention through the water modification of The Bio Water. In the case of calcium carbonate (CaCO3), with The Bio Water modified water, the gas that was dissolved under high pressure is encapsulated within the chain of water molecules (hydration) without vaporizing, and is preserved while maintaining a stable state among uniformly sized water molecules. As a result, CaCO3 reacts with water and the abundant CO2 to form water-soluble Ca(HCO3)2. CaCO3 + H2O + CO2 → Ca(HCO3)2 In the case of silicon dioxide (silica, SiO2), a phenomenon occurs where water molecules surround the silica SiO2 in the modified water. This makes it difficult for the silica SiO2 to link together, hindering the formation of a gel membrane, and making it less likely for a strong deposit layer to form as scale. On the other hand, in unmodified water, a strong layered gel membrane is formed. SiO2 + H2O → H2SiO3 *For more details, please refer to the PDF document or feel free to contact us.
