HRC70 080 ZéPAC HEAT COOL • Cascade high temperature air/water heat pumps 70°C HEATING/COOLING

The HRC70 80 ZéPAC are two air/water heat pumps in cascade that are suitable for heating and cooling. The water can be heated at high temperatures. The monoblock units are filled with the natural refrigerant propane (R290) and easily reach water temperatures up to 70°C. The devices guarentee proper operation at outside temperatures down to -20°C.
The HRC70 40 ZéPAC is a heating/cooling unit that uses 2 scroll compressors of the same capacity and with a soft starter as standard. This ensures 4 power stages and low power consumption for the whole cascade. Due to the specific construction, the device will switch to defrost mode 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.
