Product No. 16166946

Package Type Metal Pail

Product Specifications

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 an ideal thermal fluid for a broad variety of heat transfer applications across a range of industries and applications. Including, but not limited to:

Heating, Ventilation & Air Conditioning (HVAC)
Chill water & hydronic heating loops
Geothermal (ground source heat pumps)
Snow melt & Turf heating systems
Solar hot water heating
Fire water sprinkler systems
Ice skating rinks
Cold storage, refrigerated warehouses & supermarkets (secondary loop)
Thermal Energy Storage (TES)
