Chillers

There are basically five different types of chillers: reciprocating compression, scroll compression, screw driven compression, and centrifugal compression are all mechanical machines that can be powered by electric motors, steam, or gas turbines. Industrial chillers typically come as complete packaged closed loop systems, including the chiller unit, condenser, and pump station with recirculating pump, expansion valve, no flow shutdown, internal cold water tank, and temperature control. Most industrial chillers use refrigeration as the media for cooling, but some rely on simpler techniques such as air or water flowing over coils containing the coolant to regulate temperature. A chiller is a machine that removes heat from a liquid via a vapor compression or absorption refrigeration cycle. Chillers are precision machines that are very expensive to purchase and maintain.
