Spiral Condenser & WSHP Heat Exchangers

Coil Thumbnail Coil Photo

Packless spiral water-source coaxial heat exchangers operate efficiently as refrigerant condensers or refrigerant evaporators. This makes them an ideal choice for both water-source heat pumps (WSHP) and water-cooled condenser applications.

Packless heat exchangers are C-UL-US listed per the UL-207 standard and manufactured in our ISO 9001:2015 certified plant. Maximum rated working pressures are 500 psig on the water side and 650 psig on the refrigerant side.
