DOWFROST™ HD is a yellow-dyed, industrial-grade inhibited propylene glycol (PG) thermal fluid for heat transfer applications between −45°C and 160°C (−50°F and 325°F).
DOWFROST™ HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. DOWFROST™ HD (heavy duty) has a lower PG composition to allow for a higher concentration of corrosion inhibitors for maximum protection and rust prevention. These additional components do not compromise toxicity fluid and provide enhanced corrosion protection that is unsurpassed in the industry.
DOWFROST™ HD has a fluorescent-yellow color and can operate at higher temperatures than regular DOWFROST™. DOWFROST™ HD is suitable for use in environments between −50°F and 325°F (−45°C and 160°C).
DOWFROST™ HD is intended for low-toxicity, non-food processing applications and provides freeze protection down to −60°F.
DOWFROST™ HD is available in a range of prediluted concentrations and package sizes.

Dow's glycol fluids stand apart in the heat transfer fluid industry due to their dynamic properties and a broad portfolio of specialized grades of DOWFROSTTM and DOWTHERMTM with best in class performance.
Fiscal budgeting for facility maintenance is truly a tough balance. Too much or too little spending creates a domino-effect for unexpected issues, learn how to better budget with glycol fluids here.
Water is a critical aspect for any glycol-based thermal fluid, the inherent properties of water allow for efficient and effective thermal transfer. But how does water quality affect performance and system equipment? Learn how water quality can affect your system and what you can do to prepare for long-term success.
Heat transfer systems are designed to recover, transfer, and retain heat – this is especially important for systems subjected to extreme cold weather. Learn how the Dow thermal fluids provide freeze and burst protection for winter weather environments.
There are many glycol-based thermal fluids available in the market, but the so-called bargain homebrew solutions carry many hidden costs. Save yourself thousands in repair and fluid costs and learn the true value of the DOWFROST™ brands.
