Oatey 35287 Antifreeze Compound 55 Gallon

Product Description

The OATEY 35287 is a propylene glycol-based antifreeze compound formulated for maximum freeze protection in closed-loop fluid systems. Supplied in a 55-gallon container, this liquid concentrate provides reliable protection across hydronic heating and cooling circuits, potable water systems, and closed-loop solar thermal installations. The propylene glycol composition ranges from 40 to 60 percent, delivering a temperature rating up to 250 degrees F and a flash point above 212 degrees F. With a specific gravity of 1.04 and a viscosity of 10 cPs, the fluid flows readily through system piping without excessive pump load. Licensed plumbers and mechanical contractors typically handle installation in commercial and residential applications.

This antifreeze is suited for hydronic radiant heating systems, chilled-water cooling loops, potable water piping in cold-climate installations, and closed-loop solar collector circuits. The 55-gallon drum format is practical for large commercial jobs or contractor fleet stocking where multiple systems require treatment. The odorless, blue-tinted liquid allows easy visual confirmation of fluid presence during fill and bleed procedures.

Key Features

• Propylene glycol composition (40 to 60 percent) suitable for potable water and closed-loop systems
• Temperature rating up to 250 degrees F for high-temperature hydronic applications
• Flash point above 212 degrees F for safe handling and storage
• Low viscosity of 10 cPs supports efficient circulation through system piping
• pH range of 8.5 to 10 provides corrosion inhibition for system components
• Odorless blue liquid allows visual confirmation during system fill procedures

Compatibility

Designed for use in hydronic heating and cooling systems, potable water systems, and closed-loop solar thermal systems where propylene glycol-based freeze protection is required.

Installation Notes

Installation is typically performed by licensed plumbers or mechanical contractors familiar with hydronic and solar thermal system commissioning. Isolate and de-pressurize the system before introducing antifreeze fluid, and follow the system manufacturer's recommended glycol concentration for the target freeze-protection temperature. Consult local plumbing codes, including IPC guidelines, for any restrictions on antifreeze use in potable water applications. Dispose of used or drained fluid in accordance with local environmental regulations.
