The water-cooled chiller is a cryogenic design that cools entities by transferring heat absorbed from process water to an individual water source such as a river, pond or a cooling tower. These chillers are pertinent in situations where a cooling tower is at immediate disposal, or where a user demands optimal power consumption. They necessitate condenser water treatment to remove mineral buildup, the absence of which causes insubstantial heat transfer, which is antecedent to an inefficient unit. They find application in chemical and pharmaceutical processes, milk and dairy pasteurizing, food products, and plastic processing.
