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 less than 0.05, a reduction of one third!

At the headers of the hot and cold water systems for the Fukui Prefectural Hospital's air conditioning, a polar magnetic water treatment device was installed along with a dedicated circulation pump, and the circulating water was treated using a partial draw-in method. As a result, significant improvements in water quality were achieved in the hot water system, with pH and silica levels showing notable enhancements, 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 increasing 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 hot and cold water systems for the Fukui Prefectural Hospital's air conditioning ■ 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.
