Get your CO2 laser ready for the cold winter with OMTech's laser antifreeze coolant! Our self-developed 1 gallon heat transfer fluid is composed of ethylene glycol, deionized water, and corrosion inhibitors to give your CO2 laser all-around protection against freezing, overheating, and corrosion for long lasting performance. A perfect match for all of OMTech's water chillers, this safe and clean laser antifreeze efficiently removes excess heat for stable laser engraving to keep your laser tube from freezing in temperatures as low as -31°F, and continuously boasts extra low conductivity for stable laser engraving without reducing the output power. Prediluted for your immediate use, our universally compatible antifreeze coolant is a match for all CO2 lasers, from laser engravers to laser cutters and hybrid lasers.

For best results, replace OMTech laser coolant every 3 months or any time you notice dust or debris in the line.

NOTE that mixing this fluid with other coolants may lead to unwanted chemical reactions. Similarly, using automotive antifreezes in your laser will deteriorate its output power and lifespan because of their higher viscosity and pH levels.
