CO2 Laser Coolant Non Conductive 1.1 gal - Prediluted Antifreeze

Our review of this CO2 laser coolant finds it geared toward hobbyists and small shops that need a ready-to-use, low conductivity fluid to protect CO2 laser tubes. The bottom line: it is a convenient prediluted antifreeze and heat transfer fluid that keeps a tube from freezing down to -31F and removes excess heat efficiently, making it most valuable for users who want a simple tank refill without mixing or special handling. The review highlights practical performance, compatibility with common chillers, and a couple of caveats about mixing with other fluids.

Key Features

• Prediluted Ready To Use: The coolant is supplied prediluted so users can add it directly to a water tank or chiller after flushing the system with distilled or deionized water.
• Freeze Protection: Rated to protect a laser tube from freezing and bursting down to -31F, which helps in cold shop environments or seasonal storage.
• Low Conductivity: Ultra low electrical conductivity of about 10 S/cm reduces the risk of electrical corrosion and prolongs tube life without lowering output power.
• Corrosion Inhibitors: Ethylene glycol base with corrosion inhibitors and a bittering agent resists overheating and erosion to extend radiator and tube longevity.
• Universal Compatibility: Designed to work with all CO2 laser cutting machine water chillers and cooling tanks, making it a simple choice for mixed equipment fleets.
• Manufacturer Support: The product comes with US based shipping, two year general support on sealed units, and 24/7 customer service for troubleshooting.

Who It's For

This coolant is best for makers, small fabrication shops, and laser hobbyists who want a low-maintenance coolant that is safe to pour into a chiller or tank and will protect the tube in colder conditions. It suits anyone who prioritizes easy setup and a solution that avoids the added work of measuring concentrates.

Users who rely on automotive antifreeze or custom mixed coolant blends should look elsewhere, because mixing this fluid with other coolants can cause unwanted chemical reactions and degrade performance. Large industrial operations that require specialized heat transfer fluids should confirm compatibility with their systems before adopting this product.

Pros & Cons

Pros

• Ready-to-use prediluted formula saves time and reduces handling errors compared with concentrates.
• Effective freeze protection to -31F prevents burst tubes in cold environments.
• Low conductivity and corrosion inhibitors help maintain tube output and extend service life.
• Generally well regarded by customers for cooling capacity and value for money.

Cons

• Must not be mixed with other coolants or automotive antifreeze due to risk of chemical reactions and reduced tube life.
• Ethylene glycol base may be a concern for users seeking propylene glycol or other specific chemistries.
