Noble 020837-76501 Antifreeze Heat Transfer Fluid 55 Gal

Product Description

The NOBLE 020837-76501 is a non-toxic, pre-mixed antifreeze and heat transfer fluid designed for use in systems where freezing may cause damage or interfere with equipment operation. Sold in a 55-gallon quantity, this fluid is formulated to replace water and water-like fluids in closed-loop and hydronic systems where human or animal contact with the fluid is a concern. It is safe for use in systems that may have incidental contact with potable water, making it well suited for HVAC, radiant heating, and plumbing applications where food-grade or low-toxicity requirements apply.

This fluid is intended for residential and commercial HVAC systems, hydronic heating systems, radiant floor systems, solar thermal systems, and similar closed-loop fluid circuits where freeze protection and low toxicity are required. It is not suitable for automotive cooling systems. It must not be used in systems containing galvanized pipe, as the fluid may react with galvanized surfaces. Installers working on potable water-adjacent systems should verify local code compliance before use.

Key Features

• Non-toxic formula safe for systems with possible potable water contact
• Pre-mixed and ready to use — no field dilution required
• Functions as both an antifreeze and heat transfer fluid
• 55-gallon drum size suited for large system fills or service fleets
• Not compatible with galvanized pipe — verify system materials before installation

Compatibility

Designed for use in closed-loop hydronic heating, radiant, HVAC, and solar thermal systems where freeze protection and low-toxicity fluid are required. Not for use in automotive systems or in any system containing galvanized pipe.

Installation Notes

Installation and system charging should be performed by a licensed HVAC technician or plumber familiar with closed-loop hydronic systems. Shut down and depressurize the system before draining existing fluid and introducing this antifreeze. Inspect all system components, including piping material, to confirm compatibility before filling. Verify that local codes and system manufacturer requirements are met prior to placing the system back into service.
