Works great for my laser engraver, reasonable price

Works great in my laser chiller

Great stuff for cooling your CO2 laser! More balance cooling and heat Transfer. A absolute must if you’re in an outside shop. OMTech is the only place I found that sells it. Although buying direct through them it takes a long time and packaging isn’t that great, took a couple of weeks and the packaging didn’t make it, shipper sent it back, OmTech direct was gonna take weeks to verify the damage and resend so I got a refund. Buying through Amazon is faster (days), better packaging, and a much better customer experience.

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.

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

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👍 !!!

a little late but meets expectations

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.
