Air Cooled Screw Chiller is a water cooling device that produced a chilling effect by using compression pressure and releases out heat from the system by chilled air circulation in different commercial and industrial applications.

Air Cooled Screw Chiller consist of a screw compressor, air-cooled condenser, ice thermal storage unit, condenser fan, AC control system, refrigerant tank, expansion valves, tube type evaporator, and protection devices for efficient operation.


Ruidong Group Air Cooled Screw Chiller has its outstanding benefits supporting different industrial processing as given below:

  • Air Cooled Screw Chiller is steadfast and fluent in its cooling operation configured by the installation of a screw chiller with automatic scheduling that ensures compression force on refrigerant and analyzes the cooling load to maintain a set point.

  • Air Cooled Screw Chiller is featured with expansion valve and economizer that increase the cooling capacity of compressor preventing the unit from any damaging effect by high pressure.

  • Air Cooled Screw Chiller enables noise-free operation configured by the use of twin-screw compressor rotation in such a wised way producing little vibration or no voice.

  • Air Cooled Screw Chiller has outstanding reliability and is durably configured by factory testing of all units before installation as well control panel controlling temperature and pressure inside the unit.

  • Air Cooled Screw Chiller provides a cooling effect for different commercial applications by using chilled air that circulates over the condenser for efficient heat exchange.


Air Cooled Screw Chiller steadily works and provides chilling effect to different applications as:Commercial areas, hospitals, supermarkets, plastic and steel manufacturing, medical industries, food, and beverage industry, pharmaceutical industry, and chemicals processing, etc.
