Water-cooled screw chiller(View the content)

Product Description

Product Description


    Characteristics:
    Compressor:
     Featured brands imported semi-closed and semi-hermetic screw compressor reciprocating. Performance and low noise. Based on customer needs and cooling tonnage size, or the use of stand-alone package. Compressor load can automatically alternate operation, to balance the number of compressor run-time, greatly extended the deadline for the use of chillers.



    Evaporator: 
     Copper evaporator to enhance the use of internal and external screw-type tube. Threaded brass surface, brass outer surface smooth, cooling effect, and to Cylinder body evaporator insulation board 25mm thick PE insulation, non-condensing, less loss of cooling capacity.


   
Condenser: 
     Condenser using imported from foreign countries brass, trapezoidal processed into low-relief tube, enhancing heat transfer capacity. Brass surface to reduce water pressure, easy to clean maintenance.


   
Protection device: 
     Protection systems are installed with: temperature control switch, antifreeze switch, fusible bolt, high-low pressure switch, overload protection, and compressor overheating protector, compressor protectors frequent start and unusual light.


   
Computer-controlled system: 
     Developed intelligent PLC, PC-class computer-controlled system, can do remote monitoring and control, simple operation, the host and power connections. Failure rate is low and a high factor of safety, simple installation. System control are available for immediate adjustment, intuitive and reliable.
