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.
