Air Cooled Portable Chillers 5 to 30 Tons

Process liquid chillers are designed to circulate a fluid medium (typically water, or a water-glycol solution) through a process application for cooling and can supply temperatures between 20° to 65°F. These units can service a single or multiple cooling points, and are designed to be moved between process applications as the need requires. Generally, portable liquid chillers are offered in capacities from ¼ to 40 tons.

Air-cooled liquid chillers use ambient air to dissipate process heat. These units efficiently run in plant air temperatures between 60° to 95°F. Major benefits to air-cooled units are heat recovery (for supplemental heating), exhaust air ducting (for plant ventilation), and less operating expense.
