Ultra low temperature screw chiller-Fornitore globale

Low temperature screw chiller

Product Description:

characteristic:

Compressor: Selected original imported branded semi enclosed screw and semi enclosed reciprocating compressors. Good performance and low noise. According to customer needs and the size of the cooling capacity, single or multiple machine combinations can be used. The compressor can automatically alternate operation according to load changes, balancing the operating hours of each compressor and greatly extending the service life of the chiller unit.

The copper tube of the evaporator is reinforced with internal and external threads. The surface of the copper tube has threads, the outer surface of the copper tube is smooth, and the cooling effect is good. The evaporator cylinder is insulated with a 25mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity.

Condenser: The condenser uses copper pipes imported from foreign countries and processed into trapezoidal low assist pipes to enhance heat transfer capacity. The surface of the copper tube is smooth, reducing water pressure and making it easy to clean and maintain.

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

Control System: The company has developed a highly intelligent PLC and PC level computer control system, which can be used for remote monitoring and control. It is easy to operate and the host is connected to the power supply. Low failure rate, high safety factor, and simple installation. The system control can be adjusted in real-time, intuitive and reliable.

Note: The whole machine can be customized according to process requirements, including explosion-proof chillers, acid resistant chillers, stainless steel food grade chillers, integrated chillers, etc. The minimum temperature can reach minus 65 ℃, and it supports foreign 60Hz-420v-480V voltage standards.
