CW3000 water circulate only, CW5000 can both water circulate and make cool,
you can consider which chiller suitable for your work from:laser power, working time and
temperature this 3 parts.
if you laser power is 80w or more, use the machine very long time a day and your studio
temperature is hot , you do need CW5000.
20-30 degree is good for laser tube, 25 degree is best.
Any question please connect the girl, who had sell you this machine. she will help you.
