Two days ago, a customer placed an order for S&A chiller CW-5200 on alibabe. The customer is a laser manufacturer and purchased chiller CW-5200 of 1400W cooling capacity for cooling 130W glass laser tube. He used to buy a copy produce of S&A chiller, however its refregeration performance is unstable and it is faulted after running a few months. As a result he bought it again from S&A company.
