The screw chiller has the advantages of stable and reliable operation, high efficiency and low failure, good performance, low vibration and low noise, energy saving, convenient maintenance and long service life. According to customer needs and cold tonnage size, single or multi-machine combination. The compressor can be alternately operated according to the load, and the automatic energy regulation (25%-50%-75%-100%) balances the running hours of each compressor, which greatly extends the service life of the chiller.
The evaporator copper tube of the screw chiller adopts an internal and external threaded reinforced tube. The surface of the copper pipe is threaded, the outer surface of the copper pipe is smooth, and the cooling effect is good. The evaporator body is insulated by a 25 mm thick PE insulation board, and no condensation occurs, and the loss of cooling capacity is small.
