Pump group HW20

The HW20 pump group is intended for the implementation of a hot utility water circulation system in installations with a domestic hot water tank. Its design allows you to avoid incorrect installation of the domestic hot water circulation system. The HW20 group is equipped with a thermostatic mixing valve MIX THERM (35 ÷ 60 °C), with a kvs flow of 3.4, a ball valve with a thermometer, a circulation pump with a check valve and a return water thermometer. The group can be used for containers equipped with a circulation pipe as well as for containers not equipped with it.
