Water Cooled Central Chillers 5 to 180 Tons
(Single Zone & Multizone – Digital 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.
The MW Series central chiller provides precision temperature control from an economically affordable and reliable unit. Perfect for applications such as plastic injection molding, blow molding, extrusion and other industrial
applications. Product features include:
