Why Is Cooling Required?
A laser is commonly called a gun, it has very small pass ways for chilled water around the gun to insure the accuracy of the laser, is the water is too cold or hot the laser changes its beam width an its accuracy is lowered.
What Must The Cooling System Include?
Some lasers have intermediate heat exchangers that separate the de mineralised circuit and control the temperature to the fine tolerances, if this is the case then a standard chiller is acceptable.
If the chiller is direct onto the laser, a high pressure pump will be required together with a non-ferrous water circuit and +/- 1C tolerance (hot gas bypass).
