A customer is using S&A model of chiller cw 3000, with 80 w co2 laser tube, for more than a 3 years. As we suppose, it can not chill it well when we do cutting at 100 % of power. For engraving job, with less power, it is ok.

We suggest chiller CW-5000 which is capable of chilling 80w tube on 100 % of cutting power.
