Water-cooled screw chiller (Hanbell compressor single/double series) 

 Compressor: Selected imported brand-name semi-hermetic screw and semi-hermetic reciprocating compressors. Good performance and low noise. According to customer needs and the size of the cold tonnage, a single machine or a combination of multiple    machines is used. The compressor can automatically alternate operation according to load changes, balance the operating hours of each compressor, and greatly extend the service life of the chiller.

 Evaporator: The copper tube of the evaporator adopts 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 with a 25mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity.

 Condenser: The condenser is made of copper pipes imported from foreign countries and processed into trapezoidal low help pipes to enhance heat transfer capacity. The surface of the copper pipe is smooth, which reduces the water pressure and is easy    to clean and maintain. 

 Protection device: The protection system device includes: temperature control switch, antifreeze switch, fusible bolt, high and low pressure switch, overload protector, compressor overheat protector, compressor frequent start protector and abnormal    indicator light. 

 Computer control system: The company has developed a high-intelligence PLC, PC-level computer control system, which can be used for remote monitoring and control, and is simple to operate. The host is connected to the power supply. The failure rate    is low, the safety factor is high, and the installation is simple. System control can be adjusted instantly, intuitive and reliable.
