Omni-Chill PAC Series Chiller

Portable, packaged air-cooled process chiller for indoor or outdoor installations with smaller cooling loads

The Omni-Chill PAC Series Chiller is a self-contained, portable chiller complete with fluid reservoir, pump, evaporator, compressor, condenser and all necessary controls. Designed for quick and trouble-free installation, the PAC Chiller is pre-wired, pre-insulated, factory-charged with refrigerant, and skid-mounted.


Warm process water flows to the chiller, where it is cooled by the refrigeration circuit and then pumped back to the facility. Heat absorbed by the refrigeration circuit is then rejected from the condenser into the surrounding air.


The PAC Series Chiller is low-maintenance by design. Dry Coolers recommends periodically cleaning air filters and monitoring fluid levels.
