Water chillers are commonly known as refrigerators, refrigerators, water freezers, water freezers, and chillers. Due to their widespread use in various industries, their names are countless. The principle of its nature is a multifunctional machine that removes liquid vapor through a compression or heat absorption refrigeration cycle. The steam compression chiller consists of four main components: a steam compression refrigeration cycle compressor, an evaporator, a condenser, and some metering devices to achieve different refrigerants. Absorption chillers use water as a refrigerant and rely on the water and lithium bromide solution between them to achieve a strong affinity for refrigeration.
 

Characteristics of open water chillers：
       1、The components of the refrigeration system are all of international brand components, and the water tank made of pure stainless steel without coil has a lasting and stable cooling effect, with a temperature control accuracy of ± 1 ℃; 　

       2、With ultra high and low temperature display and signal output protection, configured with normally open and normally closed outputs for selection;　　

       3、The chilled water circulation system uses stainless steel multi-stage pumps and stainless steel, PVC material connections, without the worry of corrosion, and can directly use pure water or deionized water; 　　 

       4、Equipped with a water outlet pressure display meter to facilitate the adjustment of pressure and flow;　　

       5、With a flow protection device, when the water flow is too low, automatically disconnect the power supply of the laser machine to prevent the laser head from overheating due to lack of water; 　　

       6、It adopts an electronic temperature control developed independently and produced by well-known OEM manufacturers, with dual digit display, multiple settings and fault display functions, requiring only one button operation (key on), and other functions are automatically realized by memory functions; 　　

       7、The machine is equipped with movable casters for easy installation and use.　
 

Air cooled open water chiller：
       Suitable for laser processing equipment using YAG as the laser working medium, including laser marking, laser cutting, laser welding, laser drilling, laser scribing, and other equipment, with a cooling capacity ranging from 1.6 KW to 8.7 KW. Mainly used for laser cutting machines.

       The laser generator, beam controller, and electric control cabinet in a laser (laser) system can require additional cooling. The temperature requirement for frozen water is usually between 15-22 ℃, the accuracy requirement for frozen water is usually ± 1K or 2K, and some equipment may require ± 0.5K. In addition, some equipment has certain requirements for conductivity and corrosion resistance of frozen water. Therefore, the requirements for water quality are very high, and stainless steel or PVC pipes are used.

Scope of application：
       Use occasions of water chillers: mold cooling in the plastic industry, electroplating pool cooling in the electroplating industry, various cooling in the electronic industry, various cooling in the chemical industry, various cooling in the pharmaceutical industry, cooling in the food industry, constant temperature cooling in the preservation industry, and cooling by various air conditioning equipment.
