CAUTION: Mixing glycol with chlorine (calcium hypochlorite) can be extremely dangerous. A violent reaction may occur. DO NOT MIX CHLORINE WITH YOUR GLYCOL.
CAUTION: Mixing glycol with bleach (sodium hypochlorite) can be extremely dangerous. Formation of chlorinated organic compounds, explosive compounds, and/or release of chlorine gas may occur. DO NOT MIX BLEACH WITH YOUR GLYCOL.
DO NOT MIX DIFFERNT TYPES OF GLYCOL.
ALWAYS FOLLOW THE SAFETY INSTRUCTIONS ON THE GLYCOL CONTAINER.
No-Freez:
Pre-mixed 50/50 solution of Propylene Glycol and Water with burst protection up to -100°F and flow point up to -61°F. ( Unless your Boiler suggests otherwise. )
NO-FREEZ is specifically designed for hydronic, boiler and geothermal systems and is ideal for summer homes, marinas, RV's, solar units, sprinkler systems, and many other applications. It is non-toxic, contains no methanol, ethanol or ethylene glycol and is ready-to-use.
Propylene glycol is the only material safe for typical anti-freeze requirements. NO-FREEZ is a precision blend containing anti-corrosion inhibitors which takes the calculations, guesswork and possibility of errors out of protecting the system.
Use with refractometer or test strips.
Note: glycol containing systems require an expansion tank sized 20% larger then conventional water systems. The system should not contain an automatic makeup pump, since it can dilute the solution.
Features:
- Non-toxic
- Pure, high grade propylene glycol with anti-corrosion inhibitors and color indicators
- Meets NSF HT1 (#147076)
- Meets CFR 21 for appropriate use
- Does not support bacterial growth
- Non-foaming
- Rated 250F for continuous or 350F for intermittent use
