The split heat pump evaporator WPV is an outdoor unit to connect by refrigerant lines to the heat pump. The design is optimized for high capacities and a very robust operation of the heat pump. The finned coil block can be optimised to achive high COPs with different heat pump evaporations. The fan can easily controlable by a 0- 10 V signal and very energy efficient. Various innovative options bring up to a round figure.


  • High efficiency coil block.
  • Energy efficient stepless fan 230 V 50/ 60 Hz.
  • Fin spacing 4.0 mm.
  • Low noise emissions.


  • Bottom- plate heating coil, to subcool the refrigerant and ensure a condensate drain below 0°C.
  • Electric heater rods for safe and easy defrost.
  • Cover for air- inlet and air outlet, to optimise the defrost.
  • Protection grille (only in combination with covers).
