WPL 19 A

APPLICATION: Inverter air source heat pump with output-dependent control, designed as a mono block appliance for outdoor installation. Can be used for heating and DHW operation; optimised for modernisation projects due to constantly high flow temperatures. The design enables the previous model to be directly replaced and allows installation in an open space. In the „dB“ version, the duct silencers for sound reduction at the intake and discharge apertures are included in the standard delivery. Depending on the version, a noise reduction of up to 3 dB can be achieved.
EQUIPMENT/CONVENIENCE: Optimised noise reduction due to encapsulated refrigerant circuit and acoustically isolated compressor. The wide gaps between the evaporator fins create low air resistance and, in combination with the modulating fan, result in a low sound power level. The combined enhanced vapour injection/enhanced saturated vapour injection cools the scroll compressor at low outside temperatures, enabling the maximum flow temperature to be achieved all year round. In combination with the ISG (optional accessory), the heat pump controller (accessory) can be used to control the system via a home network or mobile device. With integral heat and electricity metering via refrigerant circuit data. An emergency/booster heater enables mono energetic operation. The refrigerant circuit is hermetically sealed, tested for tightness at the factory and filled with safety refrigerant R410A.
EFFICIENCY: The waste heat from the inverter is used to raise the return temperature. This increases the overall efficiency of the system. Demand-dependent and energy efficient defrosting through circuit reversal. The condensate pan is heated by the refrigerant circuit to enable efficient defrosting.
INSTALLATION: Integral anti-vibration mounts for direct connection to the heating system. The metal casing is corrosion-protected and made from galvanised, powder coated sheet steel, with an alpine white stove enamel finish.
