This means that the air-water heat pump in monobloc design can be used in new buildings as well as in existing buildings. The Aerowin Evolution was developed in cooperation with M-TEC. In operation, the heat pump has a sound power level of 45 or 50 decibels. The reason for the relatively silent operation is the inverter technology, a generously dimensioned fan in the so-called owl wing design and an evaporator with wide fin spacing.
