WW WHR - WAMAK Heat Pumps

Waste Heat Recovery Heat pumps WW WHR

Compact heat pump for heating and domestic hot water. The short closed refrigerant circuit with silent scroll compressor helps for long-term stable operation.
Use for waste heat recovery. The new technology of WHR Scroll compressors with a shifted working range to the high-temperature region with a favorable COP efficiency, which can even reach 4.2 ~ 4.5 at a water outlet temperature of 70 ~ 80 ºC and as long as the source temperature is between 30 ºC ~ 40 ºC.
Thermal energy from various industrial or ancillary processes is used as a primary source. Usually in the temperature range between 20° and 50°C. Depending on the quality and chemical composition of the process medium, the heat is extracted either directly in the heat pump or via a pre-wired heat exchanger with intermediate circuit. The heat pump then raises this temperature with high efficiency to a usable temperature for heating or hot water.
