Mr. Chen had been using S&A water chiller with small cooling capacity to cool their spindles. This time, he also wishes to use S&A CW-3000 water chiller to cool the four-axis CNC engraving machine. After having a deeper understanding of the CNC engraving machine about the heating value, S&A recommends CW-5200 water chiller for the cooling. There is an essential difference between S&A CW-5200 and CW-3000 water chiller. As a heat radiation type water chiller, S&A CW-3000 water chiller with a heat dissipating capacity of 50W/℃ is applicable to the cooling of the devices with low heat productivity. However as a refrigeration type water chiller, S&A CW-5200 water chiller is applicable to the cooling of the devices with high heat productivity. With up to 1400W cooling capacity and ±0.3℃ precisely temperature control, S&A CW-5200 water chiller has two temperature control modes (the constant temperature control mode and the intelligent temperature control mode) that can be applicable to different occasions. On the recommendation of S&A, Mr. Chen has purchased S&A CW-5200 water chiller to cool their 7.4KW four-axis CNC engraving machine.
