The air-cooled screw chiller is a key component of the compressor - the compressor uses a screw-type air-cooled screw chiller, and the unit is out of the evaporator as a gas refrigerant; after the compressor is adiabatically compressed, it becomes a high temperature and high pressure state. The compressed gas refrigerant is condensed by isostatic cooling in a condenser, and after condensation, it is changed into a liquid refrigerant, and then expanded to a low pressure through a throttle valve to become a gas-liquid mixture. Made with modern and advanced technology, the quality is excellent and the appearance is beautiful. Selected original imported brand-name equipment materials, good performance, low noise, can be changed according to load, automatic alternate operation, greatly extending the life of the chiller, excellent R22/R407C/134a (optional) refrigerant, using Taiwan "Hanzhong "Or German "Bizel" screw compressor. The unit has automatic frosting function and can be operated at low temperature. There is also a high-intelligent PLC and PC-level computer control system, which can be used for remote monitoring and control. It is easy to operate and can be adjusted in time. Low failure rate and high safety factor. Wide range of applications.
