HRC70 40 and HRC70 80 air/water heat pumps in cascade are suitable for high water temperatures. The monoblock unit is filled with the natural refrigerant propane (R290) and easily reaches water temperatures up to 70°C. The devices guarantee proper operation at outside tempartures down to -20°C.
The HRC70 40 and HRC70 80 are a heating only unit that use 2 scroll compressors of the same capacity and with a soft starter as standard. This ensures 2 power stages and low power consumption. Due to the specific construction, the device will switch to defrost mode less and the defrost cycle will be completed as efficiently as possible.
The unit maintains its high COP values even at negative outside temperatures. Possibility to cascade 3 HRC70 40units with a total power of 120kW or 2 HRC70 80 units with a total power of 160kW.
