HSN series low temperature cold room screw type parallel compressor rack
   
   	- Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit.
  	- Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation.
  	- With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency.
  	- The PLC controller monitors running compressors quantity, it maintains a maximum use rate even when only parts of the compressors are functioning.
  	- PLC controller can be set with the best running curve (maximum & minimum power comsuption), to same as much electricity as possible.
  	- With “modularized design” the risk during construction can be largely reduced, construction period can be shortened, improve the product quality controllability.
