Semi-hermetic Air-cooled Compressor Rack for Low Temperature Refrigeration

Semi-hermetic Air-cooled Compressor Rack for Low Temperature Refrigeration

Advantages:

1.The unit is equipped with semi-hermetic compressor, which is high quality and reliable.

2.Multi-parallelized compressors share exhaust pipe, inhale pipe, condenser, reservoir and etc. A refrigeration cycle system provides large cooling capacity and easy to centralized control.   

3.The structure of this unit is compact with less occupation.

4.With multi-level energy regulation, energy can be adjusted according to the change of cooling load, which can effectively reduce energy consumption

5.Minimize the impact to the unit running caused by working failure, improving performing reliability.
