No-Freez Non-Toxic Anti-Freeze, 5 gal
Brand: Utility
Part#: 18-452
made in usa
Pre-mixed 50/50 solution of Propylene Glycol and Water with burst protection up to -100°F and flow point up to -61°F.

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.
