Keep Your Cool. Use Only the Best Inhibited Glycol.

When it comes to temperature consistency during the fermentation process, vintners and brewers rely on a high-quality heat transfer fluid. Even small variations of temperature during this process can cause oiliness or other off-flavor. Don’t risk your reputation, or a “drain pour.” Go with the industry’s best fluid.

DOWFROST™ inhibited propylene glycol heat transfer fluids help enable reliable, long-lasting, and dependable performance providing necessary cooling and refrigeration for secondary fermentation vessels. Our products:

  • Comply fully with FDA & NSF regulations for low toxicity.
  • Help enable efficient heat transfer (-18°C to 120°C / 0°F to 250°F).
  • Provide optimal freeze and burst protection (to -51°C / -60°F).
  • Help prevent corrosion and fouling of heat transfer surfaces to ensure optimal temperature control and longer equipment life.
  • Made with propylene glycol that meets U.S. Pharmacopeia (USP)-Food Chemicals Codex specifications.

DOWFROST fluids are acceptable for use as a heat transfer fluid in applications where incidental contact with food and beverage products is possible.

Get the Purity Advantage

DOWFROST Heat Transfer Fluids are the only inhibited glycol made with a pharmaceutical grade of monopropylene glycol having a specified purity greater than 99.8 percent. Using our fluid will give you a competitive advantage over other secondary refrigerants on the market.

Competitor products are often made from recycled or industrial grade propylene glycols, or from glycols derived from bio-renewable sources. These glycols typically do not meet USP specifications as they contain significant amounts of impurities like ethylene glycol or diethylene glycol, which, at certain levels, affect toxicity. They may also contain other impurities, such as dioxolanes, which impart strong odors and cause excessive foam. You wouldn’t allow impurities in your final product – why accept it in your heat transfer fluid?

Beware of Swill in Sheep’s Clothing

Just as other brewers or vintners may claim their knock-off batches are as good as your product, heat transfer fluid makers sometimes claim their lower-priced options are similar to Dow quality or were made by Dow. But don’t be fooled – or risk significant damage to your pump, chiller or bright tanks. If you are unsure, or you suspect a counterfeit product, contact a Dow representative for assistance.
