Why Choose HuaZhao

Advanced Load Evaporator for Optimal Performance

The 50hz Water Cooled Screw Chiller utilizes a high-efficiency load evaporator with a gravity-type refrigerant distribution system. This setup ensures reliable operation while enhancing evaporation efficiency. The optimized arrangement of the eliminator and evaporator tube contributes to this system's exceptional cooling performance.

Efficient Oil Recovery System

Equipped with a three-stage oil recovery system, this 50hz Water Cooled Screw Chiller recovers oil efficiently during compressor operation. The process prevents impurities from entering the system, maintaining cooling efficiency and ensuring smooth functionality. By consistently recovering and supplying oil, the system prevents oil shortages and extends the operational life of the chiller.
