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

A complete Polar model PI-50CF is installed with a dedicated pump for independent circulation in a 40m3 water storage 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 effect) from the pipes, with iron levels rising 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.
