Glycol Chillers for Food & Beverage

Advantage glycol chillers deliver low-temperature, freeze-protected cooling for breweries, wineries, bakeries, and dairy plants. These sanitary systems maintain precise sub-32°F setpoints without ice formation, ensuring product quality and process consistency.

Glycol Chillers for Food & Beverage

Advantage Low-Temperature Glycol Systems

In food and beverage processing, Advantage glycol chillers are essential for applications requiring fluid temperatures below 32°F without freezing. These sanitary, freeze-protected systems support cold crashing, jacketed fermentation, dough chilling, and rapid product cooling in breweries, wineries, and bakeries.

Advantage glycol chillers feature non-ferrous fluid circuits, stainless steel pumps, brazed plate evaporators, and Copeland scroll compressors with hot gas bypass for reliable low-temp operation. Available from 1 to 540+ tons in portable, central, air-cooled, or water-cooled models, they include food-grade propylene glycol loops, tri-clamp fittings, CIP circuits, and 3-A sanitary options. Microprocessor controls with remote monitoring ensure ±0.5°F stability.

Advantage glycol systems provide critical sub-freezing cooling for fermentation, proofing, and cold stabilization while preventing ice buildup in heat exchangers. Built with UL-listed and NSF-rated components, they meet HACCP, FSMA, and USDA standards. Variable speed pumps and predictive diagnostics optimize energy use and uptime in 24/7 production environments.

Glycol Cooling Solutions Achieving precise low-temperature control in sanitary environments requires robust, freeze-protected systems. Advantage Engineering leads in glycol chillers with a full range of hygienic, high-performance units tailored for food and beverage plants.

Brewery Cold Crash: Glycol chillers drop fermenter temperatures to 32–35°F to precipitate proteins and clarify beer.

Winery Cold Stabilization: Systems maintain 25–28°F to remove tartrates and prevent clouding in white wines.

Bakery Dough Chilling: Glycol jackets cool mixers to 40–50°F for consistent dough hydration and gluten development.

Dairy Brine Cooling: Low-temp glycol loops chill brine for ice cream mix and cheese curd formation.

Fruit Juice Concentration: Glycol systems enable sub-zero evaporation without freezing.

CIP Pre-Chill: Glycol provides 34°F water for cleaning without thermal shock to stainless vessels.

Food-grade propylene glycol lowers freezing point to -20°F or below, preventing ice formation in evaporators and jackets. It offers superior heat transfer, corrosion inhibition, and microbial resistance. Glycol loops allow setpoints as low as 20°F while protecting equipment and enabling rapid temperature pull-down in high-humidity environments.

Common concentrations include:

30–35% Propylene Glycol: Freezing point ~15°F; used for 25–32°F processes like cold crash.
40–45% Propylene Glycol: Freezing point ~0°F; ideal for 20–25°F winery stabilization.
50%+ Propylene Glycol: Freezing point below -20°F; for sub-zero juice concentration or lab testing.

Advantage pre-mixes and tests glycol to FDA and USDA standards.

Glycol chillers rapidly lower jacketed fermenter temperatures from 68°F to 32–35°F over 24–48 hours. This precipitates yeast, proteins, and tannins for clearer beer. Hot gas bypass prevents evaporator freeze-up, while variable speed pumps match flow to tank size. Automated controls integrate with brewery software for recipe-driven crashing profiles.

Key glycol system maintenance includes:

Concentration Testing: Monthly refractometer checks to verify freeze protection.
pH & Inhibitor Levels: Quarterly lab analysis to prevent corrosion and bacterial growth.
Strainer & Filter Cleaning: Removes sediment from glycol loop every 3–6 months.
Evaporator Inspection: Annual defrost and cleaning to maintain heat transfer.
Pump Seal Checks: Prevent glycol leaks in sanitary environments.
