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.

Description:

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.


Application:


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.
