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.

Heat pump type: WW 30 WHR 55 WHR
