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 has a lower PG composition to allow for higher concentration of corrosion inhibitors for maximum protection & rust prevention. These additional components do not compromise toxicity fluid and provide an enhanced level of corrosion protection which 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.
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.
For low temperature applications, you can choose a propylene glycol or ethylene glycol solution with the DOWFROST™ or DOWTHERM™ portfolio. How do you know which one to choose? This article breaks down the major differences and factors you should consider when choosing a thermal fluid solution.
