Water chillers are systems that consist of a water chillers compressor, a water chillers condenser, and water chiller with internal piping and controls all within a single unit. The term "water chillers" can also refer to an overall package that includes a refrigeration plant, water chiller, air chiller, and/or water-cooled condenser.

Water chillers are refrigeration systems that cool water for industrial applications. Within a water chiller, refrigerant gas passes through a heat exchanger while water flows in the other direction on the opposite side of the exchanger. The refrigerant absorbs the heat lost by the water as a compressor compresses the refrigerant into a high pressure, high temperature gas. The gas then moves into the condenser coil over which ambient air blows. The air, moved by one or more fans, removes heat from the gas, which causes it to condense into a high pressure, warm temperature water. The water passes through the expansion valve where a large pressure drop occurs, making the water very cold. After the chilled water returns to the heat exchanger, the water chillers process begins again.

In order to provide the appropriate water chillers for applications, manufacturers will need a brief explanation of the process, along with the required heat load, temperature of the process, flow rate of the process liquid, flow rate constancy, type of chiller circuit (open- or closed-loop), pressure during the process, type of condenser cooling, temperature of the condenser cooling medium, installation location, electrical service available, type of package (including tank, pump or pumps and controls), physical restrictions, type of compressor, and any other special details.
