Industrial chillers and coolers, sometimes referred to as air cooled chillers, recirculating chillers, industrial coolers, and laboratory or benchtop chillers, are designed to remove the excess heat created by industrial equipment. Chillers and coolers hook directly to equipment and combine a pump, refrigeration system, and temperature controller. Coolant circulates through the system and carries the excess heat away from the equipment before it can interfere with the process or result in equipment malfunction. The heat is dissipated via a heat exchanger into the air or the domestic water supply.
Chillers and coolers typically consist of a bath with an integral pump, refrigeration system, temperature controller, and heat exchanger. The equipment to be cooled is attached to the cooler / chiller via hoses (typically, equipment that must be cooled has integral coils and plumbing to allow for a cooler / chiller to be attached). Coolant flows from the bath to the machinery where it absorbs excess heat and flows back to the bath which the temperature controller keeps at a constant temperature. Excess heat is carried away from the bath via a heat exchanger.
Chillers and coolers are classified as either liquid-liquid cooled or liquid-air cooled. Liquid-liquid cooling uses the facility's water supply to carry away the excess heat. Liquid-air cooling uses a fan blowing across the heat exchanger to remove the excess heat. The ambient air temperature (for liquid-air cooling) or ambient water temperature (for liquid-liquid cooling) will affect the unit's cooling capacity. A membrane switch can be sealed against various types of environments typically encountered in the portable device industry, which helps the devices perform better.
