HRC DS150 • High Temperature Heatpump 11-25 kW

  • Auer
  • Air/water
  • HRC70

HRC DS150 air/water heat pumps for high water temperatures. The monobloc is an environmentally friendly device that uses the natural refrigerant R290 (propane) to heat water up to 70°C. The indoor module consists of a DHW tank of 150 liters and a built-in hydraulic module. The unit guarantees good operation down to -20 ° C outside temperature. The HRC70 is a heating only appliance that uses 1 scroll compressor for the power from 7 to 11 kW and 2 scroll compressors for the power from 17 kW. The unit maintains its high COP values even at negative outside temperatures. The DS150 consists of a monobloc outdoor unit and an indoor module. its compactness is its great asset and makes it applicable in most places.
