Cryogenic screw chiller
Equipment characteristics
- World famous compressorAdopt bizel / Hanzhong semi hermetic screw compressor, energy saving and high efficiency.
- Microprocessor control systemThe centralized control of industrial PLC unit and the energy efficiency system of compressor can accurately control the matching of cooling capacity and cooling load of the unit, ensure the unit to operate with the best efficiency and reduce the operation cost.
- Internal integrated water break, low temperature, high and low pressure, antifreeze, phase sequence, phase loss, reverse phase, overload and other safety protection functions.
- Simple installation and reliable operationThe compressor is started with step-by-step depressurization to minimize the impact on the motor; the running balance is safe and the vibration is small; the unit structure is compact, the floor area is small and the installation is simple;
