Water chiller, either water cooled, or air cooled, is to provide chilling water through a refrigerant phase change. Essential components are compressor, condenser, expansion valve, evaporator, and relevant parts. Water chillers are typically used in industrial and commercial applications such as air conditioning, refrigeration, and process cooling. They are also used in residential applications such as air conditioning system. Water chillers are available in a variety of sizes and configurations to meet the needs of different applications.
For water cooling type water chillers, they can be installed in mechanical rooms or basements for space saving purpose. Air cooling type, on the other hand, is mostly considered to be suitable for outdoor conditions in order to attain better ventilation.
In particular, screw-type low-temperature chillers are used in production processes that require low-temperature treatment such as freezing, refrigeration, and industrial cooling. The product models are complete, which can meet the use places with different cooling capacity and temperature requirements.
The unit is mostly used in industrial and commercial cooling systems for food processing, pharmaceuticals, refrigeration and various special low temperature requirements.
