Air | water heat pumps

  • Product details

    Air | water heat pump inverter with enhanced vapour injection. Available as an outdoor or indoor installation version with corresponding accessories. Regulating the fan and the two inverter compressors allows the sound power level to be kept low. The robust metal casing is made from galvanised, powder-coated and stove-enamelled sheet steel. The refrigerant circuit is hermetically sealed, tested for leaks at the factory and filled with safety refrigerant R407C. A refrigerant circuit with two inverter compressors with demand-dependent and COP-optimised control ensures high efficiency. Enhanced vapour injection cools the scroll compressors at low outside temperatures, thereby achieving a higher heating output. The wide fin spacing of the evaporator provides low air resistance, resulting in reduced noise and improved defrosting. The 4/2-way valve enables defrosting by reversing the circuit. Equipped with electronic biflow expansion valve with separate control unit and switching via the internal heat pump control unit (IWS), for optimised overheating protection resulting in an improved COP. Time-optimised and energy efficient defrosting by circuit reversal. Heating of condensate pan via refrigerant circuit ensures efficient defrosting. With integral heat and electricity metering via refrigerant circuit data. All safety equipment is included. Heat pump manager (accessories) required for providing control.
