Corrosion prevention effect of chilled and hot water in hospital air conditioning systems [Magnetic Water Treatment Device Vol. 4]

A case where an electric control valve, which had failed and been replaced six times before installation, experienced no failures after installation.

On March 3, 2003, a polarizer was installed (on February 1, 2000), and since three years have already passed, maintenance (management) was conducted. After the installation of the polarizer, the red rust water turned into clear water about a week after treatment, and for the following three years, the water has remained clear and clean, indicating that the anti-corrosion effect can be evaluated as extremely significant. Additionally, before installation, about six electric control valves were malfunctioning and had to be replaced, but after installation, there have been no malfunctions, so the economic effect is considered to be very large. [Case Study] - Installation Location: Certain Medical Center in Tokyo - Installation Date: February 1, 2000 - Model: PI-25CF x 1 unit - Target Equipment: Air conditioning chilled and hot water system - Installation Method: Partial (5%) back method *For more details, please refer to the PDF document or feel free to contact us.
