General information 

We summarize the years of chiller controller experience, make the SL1500-CW chiller controller have better performance on anti-interference, and has passed EMC industrial standard certificate. Strong stability of 0.15-80MHz interference rejection, 4KV high voltage and surge resistance. Suitable for different types of HMI according to the request from clients, support remote control and module parallel operation.
