Schematic diagram and unit characteristics of industrial chiller:
A chiller is an energy-saving machine that achieves cooling effect through steam compression or absorption circulation. The full name of a chiller is a cooling water circulation machine, also known as a refrigeration machine, cooling machine, freezer, chiller unit, ice water machine, small chiller, industrial chiller, refrigeration unit, low-temperature chiller, laser chiller. Due to its widespread use in various industries, there are countless aliases depending on the industry.

The refrigeration system of a chiller unit consists of four basic parts: 

Compressor, condenser, throttle, and evaporator. Connect the four major components in a certain order using copper pipes to form a closed system, which is filled with a certain amount of refrigerant.

The air-cooled design adopts branded compressors and electronic control components for processing and manufacturing. The unit is equipped with leakage protection, overload protection, overpressure and reverse phase protection, refrigerant abnormal protection, and compressor over temperature protection, with a perfect combination.


The air-cooled heat exchanger features anti-corrosion aluminum fins and a low-noise external rotor axial fan, eliminating the need for additional cooling water pumps and towers. The unit has the characteristics of reliable operation, easy cleaning, strong cooling capacity, low noise, long service life, and simple and convenient operation. It can also be customized according to specific user requirements.
