1. High-efficiency screw compressor is adopted, with the most advanced tooth profile design, and various working conditions are in the best efficiency;
2. A new type of thin tooth internal thread high-efficiency heat exchange tube is adopted, and the heat transfer coefficient is 1.3 times that of ordinary high-efficiency tubes;
3. The multiple protection of the compressor completely prevents the rotor from jamming or the motor from overheating and burning. The perfect control system can monitor and control high and low pressure, exhaust temperature, and operating current in real time to ensure the safe operation of the unit;
4. The controller has many control functions such as status display, parameter setting, energy fuzzy control, fault inquiry, etc.
