Air | water heat pumps

WPL 20 basic

  • Product details

    Air | water heat pump for outdoor and indoor installation. With axial fan. Corrosion-resistant metal casing made from galvanised, powder-coated and stove-enamelled sheet steel. The casing parts are stove-enamelled in Alpine White and insulated to reduce noise. The refrigerant circuit is hermetically sealed, tested for leaks at the factory and filled with safety refrigerant R407C. Twin flexible coupling for the compressor for reduced sound power level. Generously sized evaporator for greater efficiency. The wide fin spacing enables low air resistance for noise reduction and improved defrosting. Heating connection in the appliance; anti-vibration separation by connection with flexible pressure hoses (accessory). The 4/2-way valve enables defrosting by reversing the circuit. Biflow-capable electronic expansion valve with a separate control unit and switching via the internal heat pump control unit (IWS) for optimised overheating protection and therefore a higher COP. Time and energy efficient defrosting by reversing the circuit. The condensate pan is heated by the refrigerant circuit to enable efficient defrosting. With integral heat and electricity metering via refrigerant circuit data. Including all safety equipment. WPM 3 heat pump manager (accessory) required to provide control.
