AWK EVI - WAMAK Heat Pumps

Air Source Heat pumps AWK

Compact heat pump for heating, cooling and domestic hot water designed for outdoor installation. A short closed refrigerant circuit with a silent Scroll compressor located in front of the low-height fan simplifies installation and aids long-term stable operation. Features include a double V-shaped heat exchanger, full stainless steel enclosure and robust frame construction.
Use for multi-family dwellings, suburban mixed-use buildings or commercial operations. The Urban range is based on a robust construction quality steel for all parts. High quality, long proven heat pump circuit components extend the life of the heat pump.
The primary source is the heat energy from the ambient air, which is blown by a silent fan in the shape of an owl's wing through a heat exchanger made of copper and aluminium.
