Product name: piston type parallel compressor refrigeration unit

Introduction:
Products adopt semi-hermetic piston type compressors which can be automatically controlled through pressure controller, and saving running cost. Products can be applied to industry of food, medicine, chemical and fruit storage etc. 

• several compressor working together, high reliability

• Step capacity control

• Advanced PLC control, reliable remote control

• Complete protection device

• Compact structure

Step Capacity control   
The combine of several compressors can control the output power according to the loading to achieve high efficiency and energy saving;

High reliability   
With several compressors, once one compressor has failure, the rest could operating normally to ensure the basic need of cold storage;

Safe running   
With safety protections against overloading, overheat, high pressure, low pressure etc., the unit could work normally even in very bad working conditions;

Remote control   
With special rack remote controller, all operations and control can be achieved in office room;

Space saving   
Compact structure design makes it space saving, and the unit could be located in front of or behind cold room without machine room;
The unit can control the number of operating compressors according to keep the system in the most economical conditions and save cost.

Operate in an economical way   
According to the demand of temperature, the unit senses system pressure through pressure sensor and then automatically controls the start-stop of compressors in varying amounts based on the size of the pressures, so that it is always in the best and most economical working condition for significantly saving operating costs. The parallel unit can determine the number and time of power-on compressors based on the heat load of cold storage. When a cold storage is busy for centralized stocking, many compressors work simultaneously to make the stored items be in the desired temperature in the shortest time. In case that heat load is less in winter or there are small amount of goods, one compressor’s capacity could fulfill all rooms.
