TWW WHR - WAMAK Heat Pumps

Waste Heat Recovery Heat pumps TWW WHR

Heat pump with two power stages for heating and domestic hot water. One short closed refrigerant circuit with a pair of quiet Scroll compressors and robust stainless steel plate heat exchangers. Through the connection kit, the circulation pumps can be easily and quickly connected while externally controlling their variable speed.
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.
