Product Description

Applicable Storage Temperature: -30ºC~-15ºC

Advantages:
1.The unit is equipped with Bitzer piston compressor, which is high quality and stable operation.
2. Multi-parallelized compressors share one set of refrigeration cycle system, including exhaust pipe, inhale pipe, condenser, reservoir and etc. This provides large cooling capacity and easier centralized control.  
3. With compact structure, integrated installation; less space occupation.
4. Multistage energy consumption can be regulated according to the change in cooling load, which could reduce the cost of operation.
5. Minimize the impact caused by machinary failure, develop the operation reliability.

Main Parts:
Compressor, Crankcase heater, Damping pipe, Reservoir, Oil separator, Oil balancer, Oil Filter, Pressure differential valve, Oil pressure protector(with pump), Inhale filter, Pressure controller, High-low pressure gauge, Sight glass, Oil pressure controller, Electrical box

Main tech parameters:
Remark: Below parameters are based on Refrigerant R22, please contact us for more details if any other kinds of refrigerants used.
Unit design condition: evaporation temperature -23ºC,cooling water inlet 30ºC,outlet -35ºC, CIC spray system must be added if evaperation is lower than -25ºC
