Colmac CxW modular water source heat pumps use energy collected from a fluid stream to heat domestic water to temperatures up to 185ºF. The source fluid can be any filtered, non-corrosive, pressurized stream of liquid at temperatures as low as 50°F. CxW modules can be arranged in banks to meet any capacity requirement. Their PLC interconnectivity allows multiple units to act as a single machine. All CxW models will fit through a standard 36″ door, making them ideal for retrofits and high-rise applications. They are also stackable, doubling the capacity per square foot.
