Mr. Leng,who is one of our customers from Shenzhen had ever purchased three brands of water chillers to cool their UV lasers. However more or less,all of these water chillers have encountered some failures,then the customer finally chooses an S&A CW-5200 water chiller to cool their 15W UV laser. S&A CW-5200 water chiller has up to 1400W cooling capacity with ±0.3℃ precisely temperature control. But why has Mr. Leng finally chosen S&A after the use of several types of water chillers?
