Air-cooled Vacuum Cooler
Air-cooled Vacuum Pre-cooler adopts an air-cooled condenser. It offers simpler on-site installation and operation, as it requires no water connection and can be used directly upon power supply. It is also easy to transport and suitable for vehicle-mounted applications
Air-cooled Vacuum Cooler

Main components of a pre-cooler:
1.Vacuum chamber
It is welded with carbon steel, and the structural frame is integrally welded with carbon steel. The pre-cooler door adopts a hydraulic flap door, as shown in the figure below:
2.Vacuum system
It adopts rotary vane oil pumps from Busch, Leybold, or Rietschle (Germany), with a specially customized design to prevent emulsification of the vacuum pump oil.
3.Refrigeration system
Refrigeration System: The system utilizes a German BITZER semi-hermetic screw compressor as the main refrigeration unit. It features an air-cooled finned condenser. The core components of the water trap (cold trap) are manufactured using a hot-dip galvanizing process, ensuring durability and high-efficiency water vapor capture.
4.Control System
Controlled by PLC + touch screen, featuring a user-friendly interface, one-touch start, and fully automatic operation.
