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 or beverage application.
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.
