Performance characteristics:

1. The product range is complete, including three major series: high temperature (outlet temperature -10 ℃), medium temperature (outlet temperature -25 ℃), and low temperature (outlet temperature -45 ℃)

2. Structural height optimization, using heat exchange tube plates to support the body, simple structure, compact and practical

3. The perfect combination of high-quality screw compressors and high-efficiency heat exchangers, with an energy efficiency ratio of up to 4.5

4. Four stage or infinite capacity control, accurately matched with load changes

5. The mother and child machines of the dual head unit can be freely set and automatically switched to ensure balanced wear of the compressor

6. The unit adopts multiple refrigeration circuits, and when one circuit fails, the other circuits can still work normally

7. Imported components are used for control, which are sensitive and reliable. The PLC programmable controller has powerful functions, a human-machine interface, full Chinese display, and strong user operability

8. It has a self diagnostic function, which takes certain protective measures and issues alarms when some parameters approach their limit values, so that the unit is not damaged and unplanned shutdowns are minimized as much as possible

9. Automatically record and save the alarm status and occurrence time of the last ten unit failures, and issue fault handling prompts
