Hi,
I have had two 80w CO2 laser tube broken in less then three monthes

The first time I was using a simple aquarium pump in a large bucket I didn't know I had to care too much for air bubbles so probably air bubble caused the tube to explode...
So we replaced the tube, we bough a CW3000 chiller and were super careful about air bubbles, but after just a few hours of use, power suddenly dropped down and we could find a crack in the laser tube! I am sure their were no air bubbles and the temperature stated by the cooler was 19°C.

Do I have a problem with my laser tube provider?
Do you think I should have my whole installation checked? Does anyone have clues on who could do that in Belgium (Brussels)?

Can you advise me with a reliable laser tube provider, preferably with a warranty?

Any information will be much appreciated!
