Industrial refrigeration unit WDC

stationarypassive coolingmultiple-compressor

Overview
Industrial chillers produce chilled water or water/glycol mixtures for building HVAC systems and process cooling. They extract heat from the process or air-handler coil and return cooled fluid via pumps. Two main configurations are available: air-cooled and water-cooled chillers.

Common applications

• Education facilities
• Data centers
• Healthcare buildings
• Office complexes
• Manufacturing plants
