OMTechCO2 Laser Coolant Non Conductive Liquid Cooler Heat Transfer Fluid for Laser Engraver Water Chiller, Prediluted Antifreeze Coolant for Laser Tubes, 2×1 gal Transparent Water Cooling Solution

I ordered 2 packs. Though pack was tough and excellent enough to contain the contents, but one pack delivered leaked (probably due to rough handling by USPS). I started the return process but realized that damaged container cannot be returned due to the leakage. Talked with amazon customer support and they communicated with the supplier. The supplier was kind enough to send an excellent replacement for the losses. AWESOME!!!! 👌... I will again work with them in future!. Great product, and great support👍 !!!

I found this is what OMTech wants in their chillers for CO2 lasers, okay value for the price, seems to work as designed.

I own two CO2 lasers and although cost more than other ways, I have never had a problem.A freind used water on a 150 watt maching and the tube froze and busted.

I needed coolant/antifreeze for my laser cleaning machine. My shop is heated, however, I was concerned that freezing could be an issue in the event of a power outage. I needed coolant and antifreeze for my laser cleaning machine. Although my shop is heated, I was concerned that freezing could become an issue in the event of a power outage. I spoke with the laser manufacturer, and they confirmed that this product would be suitable for my application. However, it is a bit expensive, which is why I rated it four stars. I spoke with the laser manufacturer and they stated this would work for my application. It's a little expensive so that is the reason for 4 stars.

works great

Bought two gallons of this to use in my OMTech chiller with an OMTech CO2 laser. Very happy with the results. No more laser burns on the wood.

Shipping was quick and easy.When I first bought my ontech, it had Blue coolant in it.The new Coolant is clear and I instantly thought, did they send out distilled water instead? Like any guy out there,our thought got the better of me and I ended up tasting the coolant. It's definitely coolant and distilled water......lol

You'd think OMTech would sell a bottle of coolant that's just enough to fill the tank of the industrial chiller they sell, but no, you need two of these, and this should be spelled out in big letters somewhere. Disappointing.
