HRC PREMIUM+ • High temperature heat pump 70°C

The HRC 70 air/water heat pump uses heat from nature and converts it into usable hot water. The construction of the unit makes it possible to heat water up to 70°C at negative outside temperatures without using a resistance. The unit guarantees good operation down to -20°C outside temperature. The natural refrigerant R290 (propane) has a GWP value of 3 and is therefore hundreds of times better than alternative refrigerants.
The HRC70 is a single heating unit that uses 2 scroll compressors with a soft starter as standard. This ensures 3 power stages and low power consumption. Due to the special construction of the unit, the unit will have to defrost less often and the defrost cycle will be completed as efficiently as possible. The unit maintains its high COP values even at negative outside temperatures.
