Air heat pump
commotherm LW-A

Power range 6,4 till 17,2 kW

HEATING – COOLING – HOT WATER FROM THE NATURE
The commotherm air/water heat pump is designed specially for outdoor installation. The fully galvanized, powder-coated metal housing resists every weather, and the sound insulation guarantees the quietest operation. The plant is operated with an environmental- friendly safety refrigerant. Soft start and threephase current monitoring are included as standard. A generously dimensioned evaporator unit ensures efficient and, above all, quiet operation even at the lowest outside temperatures (up to -20°C). In the so-called „silent mode“, the fan speed of the heat pump is reduced during the night hours in order to reach extremely low sound emissions. This „silent mode“ is supplied as standard and can be activated manually at any time.

Active cooling – During the summer months, the heat pump can also be used for active cooling in order to create a pleasant room climate. Cooling takes place via the floor heating or a cooling ceiling.
