I splurged and ordered an i0W CO2 Laser and decided, I really need to keep the laser cool. So, step in one cooler, just for the laser.
With a heft that shows it isn't cheap, the compressor is a serious unit, the radiator more than sufficient.
Inline with the pump system, my laser will run nice and cold, so it's lifewill be extended.
If you are getting a CO2 laser 60W or above (mine is 80W), a chiller is almost a must.
Great quality, great price and arrived seriously fast.
