Food-Grade Propylene Glycol 100% Concentrate - 1 Gallon (NSF Certified)

Industrial-Strength Cooling for Draft Lines and Cellar Tanks

Running a long-draw draft beer system or jacketed fermentation tanks requires reliable thermal transfer without risking equipment damage. This 100% concentrate food-grade propylene glycol provides the freeze protection and heat transfer your system needs to keep beer cold all the way from the walk-in cooler to the tap faucet. Because it's NSF certified for incidental food contact, it's safe to run in commercial food and beverage processing environments, including breweries, wineries, cideries, and restaurants.

Never run uninhibited glycol or automotive antifreeze in a draft beer cooling system. Automotive coolants contain toxic ethylene glycol, while uninhibited glycol quickly oxidizes, turns acidic, and eats away at your chiller components. This formula includes a specialized multi-metal corrosion inhibitor system that actively shields copper, brass, aluminum, cast iron, solder, and steel components. It prevents scale buildup and internal pitting, extending the working life of your glycol pump, heat exchanger, and trunkline tubing.

Mixing and Dilution Guidelines

This product comes as a 100% active concentrate, so you'll need to cut it with water before pouring it into your chiller bath. Always dilute with distilled or deionized water rather than tap water. Tap water contains minerals, chlorides, and hard deposits that neutralize corrosion inhibitors and lead to scale buildup inside your chiller loop.

Most commercial draft beer power packs run best at a 30% to 40% glycol concentration, maintaining bath temperatures between 28°F and 32°F (-2°C to 0°C) without freezing the lines or overworking the compressor. Fermentation cooling systems operating at sub-freezing temperatures may require a higher concentration. Always check your chiller manufacturer's manual and verify your mixture with a handheld refractometer calibrated for propylene glycol.
