After the cooling water system of the evaporative condenser has been used for a long time, the evaporation of water will increase the concentration of impurities in the water, the multiplication of microorganisms, etc., resulting in increased scale on the surface of the cooling coil, and impurities on the surface of the water baffle and galvanized sheet. It causes the problems such as reducing cooling efficiency, slowing heat dissipation, corrosion of equipment, and reducing service life of the evaporative condenser. During use, proper maintenance can provide the service life of the evaporative condenser.
