COMPAX

Compax Modular Chillers are available from 3 to 70 ton modules and can also operate as reversible heat pumps. The tube-in-shell heat exchangers allow for high efficiencies (exceeds ASHRAE 90.1) and can also provide condenser water temperatures in excess of 135 F. Truly modular, they can be installed mere inches apart and are front serviceable.
