Why E2 alarm is indicated in process chiller which cools cnc bending machine?

When something goes wrong, the process chiller would send the alarm signal to the CNC bending machine and there would be alarm codes indicated on the control panel of process chiller. If E2 is indicated, that means there is ultrahigh water temperature alarm. That could result from:

1.The heat exchanger of process chiller is so dusty that it can not dissipate its own heat properly;
2.The cooling capacity of process chiller is not enough;
3.The temperature controller is broken;
4.There is refrigerant leakage. 
After locating the actual reason, users can remove the alarm by solving the related problem.

After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.
