LIEBERT DRYCOOLERS
Liebert drycoolers are designed to be used in conjunction with water cooled refrigeration and air conditioning machines as well as a variety of commercial and industrial applications requiring the rejection of heat from machinery or processes via a cooling fluid. During periods of low ambient temperatures, drycoolers may assist or replace the capacity requirements of mechanical chillers for a “free cooling” effect.
Liebert offers a full range of control options as well as expansion tank and pump packages. For cooling fluids other than water or water/glycol mixtures, contact Liebert, Heat Transfer.
