DOWFROST™

Made with DOW PuraGuard™ Propylene Glycol USP/EP, a pharmaceutical grade of monopropylene glycol with specially formulated packages of food grade industrial inhibitors that help prevent corrosion.

Regular DOWFROST™ inhibited propylene glycol (PG) DOWFROST™ is comprised of about 96% PG and 4% corrosion inhibitors. All ingredients are food safe, that is to say they are classified as GRAS (generally regarded as safe) by FDA and are approved as direct food additives. DOWFROST™ is the product of choice for the food processing industry. It is undyed and has water white appearance. DOWFROST™ offers effective heat transfer over a slightly narrower temperature range than DOWTHERM™ fluids: from 0 F to 250 F. The higher minimum recommended temperature for PG based fluids is because PG has higher viscosity and is more difficult to pump at low temperature. DOWFROST™ inhibited PG can provide freeze protection down to -60 F. DOWFROST™ is offered is various concentrations and package sizes.

DOWFROST™ HD

or beverage application.

A formulation of propylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed fluorescent yellow to aid in leak detection. Not approved by the USDA or FDA for food use, and is not suitable for food...

DOWFROST™ HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. The lower PG content in DOWROST™ HD allows for additional corrosion inhibitors including some which are not approved by FDA as direct food additives. 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 is capable of operating at higher temperatures than regular DOWFROST™: from 0 F to 325 F. DOWFROST™ HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F. Dowfrost™ HD is offered is various concentrations and package sizes.

DOWTHERM™ 4000

A formulation of ethylene glycol that features one of the highest maximum use temperature of any glycol, operating temperature ranges -60°F to 350°F. The fluid is dyed fluorescent orange to aid in leak detection.

DOWTHERM™ 4000 inhibited ethylene glycol (EG) is comprised of about 92% EG and 8% corrosion inhibitors and has a bright fluorescent orange color. The lower EG content allows for a higher concentration of corrosion inhibitors which in turn means DOWTHERM™ 4000 is capable of operating at higher temperatures than DOWTHERM™ SR1 i.e. from -20°F to 350°F. This makes DOWTHERM™ 4000 a higher end, niche type product which is also capable of providing freeze protection down to -60°F.
