Review: Works Great and Handled a Sub-Zero Winter Just Fine - This coolant does exactly what laser coolant is supposed to do, and it does it well. It worked great in my setup, and I had no issues with it. It also made it through a sub-zero winter just fine, which gave me a lot of confidence in it. It’s a solid choice if you want something dependable for your laser chiller system.
Review: Glycol for CO2 laser systems - Arrived with no damage. Pale Blue glycol - works well. No odor. Reasonable cost.
