MHI heat pump can supply hot water at 90℃
4th October 2025
JAPAN: Mitsubishi Heavy Industries has developed a centrifugal heat pump for the Japanese market, which effectively uses waste heat to supply hot water at 90℃.
The ETI-W, with its large capacity of up to 640kW, uses the heat emitted from factory production processes as the heat source. This enables its use in high-temperature applications that were traditionally handled by conventional boilers.
With a COP of 4.01, the ETI-W uses low GWP R1233zd(E) refrigerant. It also incorporates an inverter starter panel within the main unit and a shell-and-tube heat exchanger, similar to MHI’s ETI-Z series centrifugal chillers.
