Main components of a pre-cooler:
1.Vacuum chamber
The vacuum chamber is made of welded carbon steel, and the structural frame is integrally welded from carbon steel as well. The chamber and the unit are designed to be separate (the unit is placed outdoors and the heat dissipates outdoors during operation, which will not affect the indoor temperature)). The pre-cooling door is a sliding 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
The German Bitzer semi-hermetic screw compressor is used as the main refrigeration unit, and a self-made evaporative condenser is used as the condenser. The core components of the water catcher (cold trap) are manufactured using the hot-dip galvanizing process. All refrigeration valves are of the Danish Danfoss brand, ensuring durability and excellent water capture performance
4.Control System
Controlled by PLC + touch screen, featuring a user-friendly interface, one-touch start, and fully automatic operation.
