SPecialized Chiller Systems

Northern Air Tru-Temp™ DX Packaged Chiller Systems are a packaged cooling solution that combines all components of a chilled fluid system into a single enclosure. A direct expansion refrigeration method is used to absorb heat from a liquid source such as water, glycol, or brine. Dual or single circuit brazed plate heat exchangers are combined with a circulating pump and buffer tank to provide a complete cooling package.

Our chiller systems are self-contained and can be wall mounted, roof mounted, skid mounted, or mobile and designed and built to withstand and operate in the most harsh and rugged environments without disruption.
