CHOFU Seisakusho Co., Ltd. is a Japanese manufacturer of heat pumps and hot-water systems, headquartered in Shimonoseki. Since 1954, CHOFU has stood for energy-efficient heating and hot-water technology made in Japan – today with a clear focus on heat pumps using natural refrigerants.

At the centre of our show presence is the R290 monoblock range: air-to-water heat pumps for heating and cooling with the natural refrigerant propane (R290, GWP 3). They operate independently of the HFC phase-down under the F-Gas Regulation, which makes them future-proof. The range covers roughly 4 to 14 kW and is available in single- and three-phase versions.
