Water Cooled Central Chillers 5 to 40 Tons
(Single Zone – Thermostat Control)
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 process at once.
Water cooled liquid chillers use a plant water supply source (tower water, city water, or well water) to dissipate process heat. Major benefits to water-cooled units are less capital expense and less maintenance.
