Red water countermeasures (18 years after construction, 85 households) [Magnetic water treatment device Vol. 5]

Red water countermeasures (18 years after construction, 85 households) [Magnetic water treatment device Vol. 5]

A Polar model PI-50CF is installed with a complete set of dedicated pump for independent circulation in a 40m3 water receiving tank!

The S.S. Heights in Shimizu, Shizuoka City, has reached nearly 20 years since its construction, so we installed a polarizer for the purpose of countering red water (protecting the water supply pipes). One month after installation, there was a slight outflow of rust (rust leaching action) within the pipes, causing the iron content to rise from 0.04 to 0.16. Three months later, it decreased to 0.13, and after six months, it returned to 0.04, demonstrating an exceptionally long-lasting rust prevention effect. 【Case Study】 ■ Installation Date: October 16, 2002 ■ Installation Location: S.S. Heights in Shimizu, Shizuoka City (85 households) ■ Model: Polarizer Magnetic Water Treatment Device PI-50CF (Connection Diameter 50A) ■ Installation Method: Installed in an independent circulation system with a dedicated circulation pump in the water storage tank ■ Installation Details: 85 households, 18 years since construction, water storage tank (effective 40m3) ■ Purpose: Corrosion prevention to suppress aging of the water supply pipes *For more details, please refer to the PDF document or feel free to contact us.

Corrosion prevention effect of newly built air conditioning chilled and hot water【Magnetic Water Treatment Device Vol.5】

Corrosion prevention effect of newly built air conditioning chilled and hot water【Magnetic Water Treatment Device Vol.5】

The iron content of the treated hot and cold water has decreased from 0.15 to below 0.05, which is a reduction of one third!

At the headers of the cooling and heating water system of Fukui Prefectural Hospital, a polar magnetic water treatment device was installed along with a dedicated circulation pump, and the circulating water was treated using a partial draw-off method. As a result, significant improvements in water quality were achieved for the hot water system, with pH and silica levels showing marked enhancement, and the Langelier index rising from -1.9 (highly corrosive) to +0.9 (non-corrosive). The cold water system also showed significant improvements in water quality, with the Langelier index changing from -1.9 (highly corrosive) to -0.2 (very slight corrosion). However, the iron content in both the treated hot and cold water decreased from 0.15 to below 0.05, a reduction of one-third, indicating that the risk of corrosion is negligible. [Case Study] ■ Installation Location: Headers of the cooling and heating water system of Fukui Prefectural Hospital ■ Polar Model - For cold water system: Model PI-50CF × 1 set (Trial operation on November 1, 2003) - For hot water system: Model PI-50CF × 1 set (Trial operation on November 1, 2003) (Size selection was carried out by our company) *For more details, please refer to the PDF document or feel free to contact us.

[Polar Technology Case Study] Confirmation of anti-corrosion effect on air conditioning chilled and hot water pipes after 17 years and 5 months.

[Polar Technology Case Study] Confirmation of anti-corrosion effect on air conditioning chilled and hot water pipes after 17 years and 5 months.

The remaining lifespan of the cold and warm water pipes is estimated to be over 20 years! Thanks to Polar's rust prevention, there are no rust lumps on the inner surface of the pipes.

We would like to introduce a case where the anti-corrosion effect was confirmed on air conditioning chilled and hot water pipes 17 years and 5 months after polar treatment. Due to the anti-corrosion action of the polar treatment, there are no rust lumps on the inner surface of the pipes, which are covered by an extremely thin, dense, and uniform anti-corrosion film that has absorbed minerals. This film prevents the reaction (corrosion) between oxygen in the water and iron, thus providing corrosion protection. [Case Study] ■ Location: A certain major home improvement center ■ Installation Date: October 2002 (17 years and 5 months have passed since installation at the time of new construction) ■ Purpose: Anti-corrosion measures for newly installed air conditioning chilled and hot water equipment *For more details, please refer to the PDF document or feel free to contact us.

Measures Against Red Water (2.5 Years After Construction) [Magnetic Water Treatment Device Vol. 8]

Measures Against Red Water (2.5 Years After Construction) [Magnetic Water Treatment Device Vol. 8]

All analysis items are within drinking water quality standards! Cases demonstrating effects equivalent to those of chemical additives.

Tokyo Max Beauty College did not have red water at that time, but it was treated with chemicals as a future measure against red water. They discontinued that and installed a Polar system, which had been confirmed effective in other buildings, for the purpose of preventing red water. The water quality analysis report one month after installation showed that all analysis items were within drinking water quality standards. The iron content was also low, and the treatment by the Polar system demonstrated effects equivalent to the chemical treatment before the installation of this system. Future expectations include prevention of skin irritation. [Case Study] - Installation Location: Tokyo Max Gakuen Tokyo Max Beauty College (2.5 years after construction) - Installation Date: August 29, 2001 - Polar Model: PI-32CF (3-point set) complete set *For more details, please refer to the PDF document or feel free to contact us.

Measures against scale and corrosion in newly constructed cooling water systems [Magnetic Water Treatment Device Vol. 13]

Installed using a pump intake method! It processes 10% to 15% of the cooling circulating water volume.

We will introduce measures against scale in newly constructed cooling water systems. In 2001, JUS Citizen Hospital (Osaka City) was completed. At that time, our Polar system was introduced for air conditioning. For two absorption chiller/heaters of 300RT each, "PI-100F" was installed with a pump, processing 10% of the circulating water volume of 10m3/min as standard. Additionally, "PI-32CF" was installed with a pump for the cooling water of the cogeneration self-generating system (CT-100RT). Due to the high temperature of the water, 15% of the circulating water volume of 1035L/min is processed as standard. [Overview] ■ Installation Location: JUS Citizen Hospital (Osaka City) ■ Installation Date: June 16, 2001 ■ Installation Method: Pump intake method ■ Installation Details: Processing 10% to 15% of cooling circulating water volume ■ Installation Purpose: Prevention of scale, corrosion, and water quality purification in the cooling water system *For more details, please refer to the PDF document or feel free to contact us.

Hydroflow Electromagnetic Water Treatment Device [Overview Video]

Hydroflow Electromagnetic Water Treatment Device [Overview Video]

Generate an electromagnetic field in water to achieve scale prevention, rust prevention, and slime suppression!

The radio frequency signal transmitted from the transmitter is used to create an electromagnetic field for water treatment inside the pipe, using an electromagnetic field generation device and a ferrite ring fixed around the piping. The magnetic field is formed in a ring shape inside the pipe, perpendicular to the flow of water, while the electric field is formed radially from the center of the pipe towards the inner surface. The effective range extends 5,000 meters upstream and downstream from the installation location of the device.
