The water chiller is mainly used with YAG lasers. This chillers are of medium cooling capacity from 3 kWatts to 7 kilowatts. They can be placed on the shop floor or in an external sheltered environment. They are either air or water cooled type. Air cooled type will have exhaust fans to extract the heat into the environment from the refrigeration coils whereas water cooled type will be cooled by a running water supply from an external source. This source can be the central factory air-conditioning cooling tower water.
The chillers provide a source of pumped recirculating chilled water to the equipment to be cooled. The chill water can be adjusted normally in the range from 10 to 30 degrees centigrade. Freezestat is built in to prevent water freezing. The chillers are environmental friendly as it is CFC free.
