Softened water tank is to soften the common hard water by electronic means. Its purpose is to minimize the scale produced by air conditioning pipes, because if there is scale on the pipe wall, it will reduce the efficiency of refrigeration (heat). Especially in winter, it needs to be softened.

It is widely used to soften the make-up water of steam boiler, hot water boiler, exchanger, evaporation condenser, air conditioner, direct fired machine and other systems. It can also be used in hotels, restaurants, office buildings, apartments, home and other domestic water treatment and food, beverage, wine, laundry, printing and dyeing, chemical industry, medicine

And other industries.
