The 16L water softener (made in EU) consists of the filler column, 12L Purolite softening resin, the brine tan, the salt in tablet form and the “valve” (made in China) which regulates the function of resin regeneration. It can be programmed through the LCD screen in English. It has a built-in By-Pass with which we regulate the desired water hardness. It has the ability to absorb salts (calcium and magnesium ions) for certain liters of water until it is saturated. After saturation, the resin is rinsed with the brine created in the brine tank and made ready for use again. Complete removal of salts provides protection for the pipes and appliances of the home or business. It is placed in the central water supply and is an ideal choice for areas with high concentration of salts in the water. Necessary condition is the connection with drain and electricity.
