WPL 18 E

Air | Water heat pump with steam intermediate injection for heating. Can be used as outdoor or indoor installation variant with corresponding accessories. The cladding consists of a robust metal housing made of hot-dip galvanized, powder-coated and stove-enamelled steel. The refrigeration circuit is hermetically sealed, factory tested for leaks and filled with the R407C safety refrigerant. Double vibration decoupling of the compressor to reduce the sound power level. The intercooler injectors cool the scroll compressor at low outdoor temperatures and achieve higher heat output. The large finned spacing of the evaporator allows for lower air resistance for sound reduction and better defrosting. The 4-2 way valve allows the circulation reversal. Biflow-capable electronic expansion valve with its own control and control via the internal heat pump control (IWS) to optimize the overheating control and thus to improve the COP. Time-optimized and energy-efficient circulation reversal protection. Heating the condensate pan through the refrigeration circuit for efficient defrosting. With integrated heat quantity and electricity metering via cooling circuit data. Including all safety devices. Heat pump manager WPM 3 (accessory) necessary for control.
