Get your CO2 laser ready for 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 lasting performance. A perfect match for OMTech's water chiller, this safe, clean, and nontoxic laser antifreeze for winterizing boasts extra low conductivity to keep your laser tube from freezing even at -31°F, and continuously removes excess heat for stable laser engraving without reducing the output power. Prediluted for your immediate use, our universally compatible antifreeze is ready to use for all CO2 lasers, from laser engravers to laser
cutters to hybrid lasers.

NOTE that the mixed use with other laser coolant may lead to chemical reactions; using vehicle coolant for your laser will deteriorate its output power and lifespan. For best results, replace the coolant every 3 months.

Running a professional CO2 laser engraving business in Australia means dealing with varying temperatures that can wreak havoc on your equipment. To ensure your machine operates at peak performance, using a specialized cooling solution is non-negotiable. The OMTech CO2 Antifreeze Laser Coolant is a premium, non-conductive liquid specifically engineered to protect your laser engraver and water chiller from the most demanding environmental conditions.

Superior Thermal Stability: From -35°C to 108°C

One of the most critical factors in laser maintenance is preventing the water in your cooling system from freezing or boiling. This self-developed heat transfer fluid offers an impressive freezing point of -31°F (-35°C) and a boiling point of 226.4°F (108°C). Whether you are operating in a freezing workshop during a southern winter or a high-heat environment, this coolant ensures your laser tube remains at a stable temperature, preventing cracks and thermal stress that could lead to costly replacements.

The Critical Importance of Low Conductivity

Unlike standard tap water or automotive coolants, the OMTech laser coolant is a non-conductive liquid with a conductivity rating of 10±5 µS/cm. Maintaining low conductivity is essential for CO2 lasers because high-voltage electricity travels through the tube. Using a conductive fluid can cause electrical arcing, which damages the power supply and the tube itself. By utilizing a mix of ethylene glycol and deionized water, this solution provides the safety your high-precision electronics require.

Why You Should Avoid Vehicle Coolant

Many hobbyists make the mistake of using automotive antifreeze in their laser chillers. However, vehicle coolants often contain silicates and phosphates designed for metal engines, which can coat the internal glass of your laser tube, significantly reducing output power and laser lifespan. OMTech’s formula is specifically free from these harmful additives, ensuring your beam remains sharp and powerful for every project.

Advanced Corrosion Protection for Long-Term Reliability

Corrosion is the silent killer of water-cooled systems. This blue-tinted coolant is infused with advanced corrosion inhibitors that prevent the buildup of rust and scale inside your chiller and laser tube. By maintaining a stable pH value between 7.3 and 8.3, the fluid protects the integrity of your internal components, ensuring a clean flow and efficient heat exchange for years to come.

Maintenance Made Simple

OMTech has designed this product for maximum convenience. It comes pre-diluted in a 4-litre (1.1 gallon) bottle, meaning you can pour it directly into your CW-3000, CW-5000, or CW-5200 water chiller without the hassle of mixing. For the best results and to maintain optimal performance, it is recommended to replace your coolant every three months.

Secure Your Laser's Future Today

Don't let temperature fluctuations or internal corrosion compromise your productivity. The OMTech CO2 Antifreeze Laser Coolant provides the all-around protection your machine deserves. Visit the OMTech AU store today to secure your supply and keep your laser engraving business running smoothly regardless of the season.
