The resin softening system is based on the principle of ion exchange. In this system, small grains called resins capture hardness minerals in Tue water and release sodium ions instead. This process reduces the hardness of the water, preventing the accumulation of lime and the formation of soap bubbles, which cause negative effects.

In this system, there is a resin tank and a control unit. The resin tank houses the resin grains inside and performs the necessary operations to soften the water. The control unit controls the operation of the system and performs refilling or flushing operations if necessary.
