Screw Type Parallel Unit
Features:the body use the semi-hermetically refrigeration compressor, the refrigeration control system of high level of automation, which achieve the parallel compressor operation, it is more stable and reliable than the traditional ammonia refrigeration system. Automatic control system of unit is controlled by imported programmable logic controller(PLC), to realize automatic safety protection in case of open phase,over-voltage,under-voltage,over-current,oil pressure,high pressure,low pressure and electric motor overloading.
Refrigeration Capacity Range: high temperature screw type parallel unit, middle temperature screw type parallel and low temperature screw type parallel unit, according to customer's demand to design unit
Application refrigerant: suitable for R22, R404A,R507A and etc.

 

 

Features:

JZBLG series screw compressor unit is composed of single or multiple sets of parallel semi-hermetica screw compressor,sharing high pressure,low pressure and oil system,form the intelligent control of the refrigeration unit. According to the customer actual need, can provide evaporation temperature +12.5~-50℃. The compressor unit adopts the design programming of the PLC computer control or single chip microcomputer control, which can realize the lack of phase,over voltage,over current,oil pressure,high pressure,low pressure,electronic motor overload automatic safety protection. PLC control can realize compressor automatic balance running time,in order to prolong the service life of the compressor, and control multiple sets of parallel operation of the compressor, to ensure that match the refrigeration system of cold quantity demanded, the compressor has been working under a state of high efficiency, so as to achieve the aim of maximum energy saving. The unit can be widely used in food processing,quick-freezing,cold storage,fruit and vegetable preservation,chemical,pharmaceutical,military and scientific research and so on all walks of life.
