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.
