ComStar® 5 Gallon Geothermal-M® Methanol Heat Transfer Fluid for Geothermal Systems

Aluminum-safe propylene glycol-based heat transfer fluid used in a wide range of industrial, construction, and infrastructure applications. Its low acute toxicity makes it especially suitable for applications where toxicity is a concern.

DOWFROST™ Heat Transfer Fluid is the only inhibited glycol made with DOW PuraGuard™ Propylene Glycol USP/EP, a pharmaceutical grade of monopropylene glycol with specified purity greater than 99.8%. By contrast, competitor products are often made from recycled or industrial grade glycols, or from glycols derived from bio-renewable sources. These glycols typically do not meet USP specifications as they contain significant amounts of impurities like ethylene glycol or diethylene glycol, which at certain levels affect toxicity. They also may contain certain other impurities, ...

Aluminum-safe propylene glycol-based heat transfer fluid used in a wide range of industrial, construction, and infrastructure applications. Its low acute toxicity makes it especially suitable for applications where toxicity is a concern. Features: Provides long lasting and efficient corrosion protection, particularly for aluminum alloys Free of nitrite, borax and CMR (carcinogenic, mutagenic and reprotoxic) Long fluid lifetime, lowering maintenance cost

A formulation of 94% propylene glycol and a specially designed 6% package of industrial corrosion inhibitors. Only inhibited glycol made with DOW® PuraGuard™ Propylene Glycol USP/EP, a pharmaceutical grade of monopropylene glycol with specified purity greater than 99.8%. By contrast, competitor products are often made from recycled or industrial-grade glycols or from glycols derived from bio-renewable sources. These glycols typically do not meet USP specifications.

ANTI-FREEZE FOR WET FIRE PROTECTION SPRINKLER SYSTEMS Fire Safe anti-freeze protection fluid is glycerin based which is in compliance with the recommendations of NFPA 13. Systems using Fire Safe are assured flow protection of -15°F and burst protection of -50°F. Fire Safe is ready to use and should not be diluted. Check freezing protection each season using a hydrometer to test the specific gravity. The specific gravity should be at 1.130 at 60°F. If specific gravity is less than this number, meaning weakened, then empty system and replace with New Fire Safe. -50° ...
