Air Cooled Central 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. Central units provide enough capacity to serve multiple process applications. Generally, central liquid chillers are offered in capacities from 5 to 180 tons and can serve several processes at once.

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.
