About Us

Ruidong Group Co.,Ltd. was founded in 2011 as an enterprise specializing in the design, manufacturing, and installation of high efficiency central air conditioning equipment. Our primary products include centrifugal water cooled chillers, water cooled screw chillers, water cooled scroll chillers, and many more. Upon request, customized heat pumps are available. We also manufacture central air conditioning terminal units, firefighting and ventilation units, cooling tower units, and other air conditioning system components.

This wide selection of products covers a broad range of applications from small, residential installations to industrial and municipal cooling and cold storage uses. Our cooling equipment has been installed in Kazakhstan, Russia, South Korea, Canada, Iran and many other countries around the world.

Workshop production
  • Large-scale processing equipment
  • Assemble line
  • Assembly line

Here at Ruidong, we operate 4 large-scale processing and production workshops. In these facilities we manufacture, test, and store fans, water chillers, and all other air conditioning equipment components. All of our production operations are carried out according to strict quality requirements and techniques.

Air conditioning equipment testing center

1. Our company utilizes a 17-station lab for the testing of our air conditioning products. The water cooled chiller and heat pump testing machine in the lab has a detection range from 14kW to 7000kW.
2. An aerodynamic measurement system performs aerodynamic performance testing of fans with 3000-120000m3/h and air conditioners.
3. Advanced 3000kg horizontal and vertical vibration laboratory performs simulation tests for road transport cooling units.
4. The semi-anechoic chamber is designed to perform all-around noise detections for products. The online laboratory can satisfy the quick delivery requirements for products.


Ruidong Group operates a R&D center which was established for the strategic cooperation with Tsinghua University, Peking University, University of Science and Technology of China, thermos-technical teaching and research office of Tianjin University, Tianjin University of Commerce, China Institute of Refrigeration and other scientific research institutions. The R&D team is made up of many different industry experts, professors, senior engineers, and other talented individuals. The team has led to over 100 approved patents for central air conditioners, pressure vessels and many other components.
