No-Freez Non-Toxic Anti-Freeze / Glycol (5 Gallon)

No-Freez Non-Toxic Anti-Freeze / Glycol (5 Gallon)

No-Freez is a chemically balanced inhibited propylene glycol solution engineered to provide worry-free freeze protection for hydronic heating systems, snow melting systems, and closed-loop applications. This 5-gallon container delivers 640 fluid ounces of non-toxic antifreeze formulated to protect systems down to -100°F burst protection temperature while maintaining flow capability to -61°F.

Key Features & Benefits

• Propylene Glycol Base: Non-toxic formulation safe for potable water systems and environmentally sensitive installations
• Inhibited Formula: Chemically balanced corrosion inhibitors protect system components including steel, copper, aluminum, and solder joints
• Burst Protection to -100°F: Safeguards piping and equipment from freeze damage in extreme cold conditions (expansion point protection to -100°F)
• Flow to -61°F: System maintains liquid circulation capability at temperatures as low as -61°F
• 5-Gallon Volume: 640 fluid ounces of ready-to-use or dilutable glycol solution for medium to large system fills
• 50% Propylene Glycol Blend: Fully inhibited concentration ready for dilution or direct use depending on required freeze protection level
• Compatible with PEX Tubing: Approved for use in radiant floor heating systems with cross-linked polyethylene piping
• Compatible with Copper Pipe: Safe for copper, brass, and ferrous metals commonly found in hydronic systems
• Multi-Application Use: Suitable for boiler systems, radiant heating, snow melting systems, and solar thermal installations

Compatibility & Requirements

This glycol is compatible with copper, steel, aluminum, brass, and PEX tubing commonly used in closed-loop hydronic heating and snow melting systems. A qualified installer familiar with glycol-based systems should perform system charging and concentration testing. Calculate the required glycol-to-water ratio based on the lowest expected ambient temperature using the protection charts in the Product Overview. System pumps and boilers may require sizing adjustments to account for the higher viscosity and reduced heat transfer capacity of glycol solutions compared to water. Check local codes for glycol use in potable water heating applications. Glycol reduces the heat exchange efficiency of in-floor systems compared to water-only systems.

Installation & Care

Drain the existing system completely before introducing No-Freez glycol. Mix glycol with clean water at the concentration specified for your target freeze protection level. Fill the system using a dedicated glycol feeder or pump station to ensure complete air purging. Test the freeze protection level using a refractometer or the Cryo-Tek Anti-Freeze (Glycol) Test Kit after initial fill and annually thereafter. Maintain system pH between 8.5 and 10.5 to preserve corrosion inhibitor effectiveness. Replace glycol solution every 3 to 5 years or when inhibitor depletion is detected through testing. Do not mix No-Freez with automotive ethylene glycol antifreeze. This product may be blended with additional propylene glycol antifreeze from other manufacturers provided both are propylene glycol-based formulations. Consult the Safety Data Guide for handling information.
