Food & Beverage Processing

Chilling & Freezing

DOWFROST™ and DOWCAL™ N Inhibited Glycol-based Heat Transfer Fluids offer advantages in a variety of chilling/freezing and defrosting/dehumidifying applications. Breweries, wineries, dairies and fruit processors use DOWFROST and DOWCAL N Fluids to cool products during processing. They are also used by restaurants, bars, and in vending machines to cool liquid beverages.

The ingredients in DOWFROST and DOWCAL N Fluids are considered safe by the U.S. FDA food additive regulations¹ for use in applications where incidental contact with food products or potable water is possible, including immersion freezing of wrapped meat, poultry, fish, seafood, vegetables, and fruit or winterization of RV plumbing systems. Both fluids are low in toxicity and odor, and virtually tasteless — important benefits in any food application.

Defrosting/Dehumidifying

DOWTHERM SR-1 and DOWCAL 10 inhibited ethylene glycol fluids are sprayed on refrigeration coils in walk-in freezers and cold rooms to help remove condensation and maintain optimum chilling efficiency. Glycols mix with condensation from the coils, lowering the freeze point of the water to prevent frost formation. These sprayed fluids can also remove moisture from the air to control humidity.

DOWTHERM SR-1 and DOWCAL 10 inhibited ethylene glycol fluids may not be acceptable in some food applications. Contact your Dow representative for additional information.
