Why Propylene Glycol for Food & Beverage?
FDA GRAS Status
Propylene glycol is Generally Recognized As Safe by the FDA (21 CFR 184.1666). Orders of magnitude less toxic than ethylene glycol.
NSF HT1 Certification
Approved for incidental food contact up to 10 ppm per FDA 21 CFR 178.3570. The industry standard for food processing heat transfer.
Pink Dye = Fast Leak Detection
Every NovaGlycol product is pink-dyed. If your heat exchanger leaks, you’ll see it immediately — before contamination becomes a food safety incident.
Multi-Metal Corrosion Protection
Our inhibitor package protects steel, cast iron, copper, aluminum, brass, and solder — every metal found in food processing heat exchangers.
Common System Types
Glycol Chillers
Central chilling for fermentation tanks, walk-in coolers, process cooling. Typical setpoint: 25–28°F.
Jacketed Tanks
Temperature-controlled fermentation, pasteurization, and mixing vessels with glycol jackets.
Plate Heat Exchangers
Compact, high-efficiency heat exchange for rapid cooling of wort, milk, juice, and liquids.
Cold Storage HVAC
Refrigeration systems in cold storage warehouses and food distribution centers.

View Product →Frequently Asked Questions
What concentration should I use in my food processing chiller?
Most food processing chillers run 30–40% PG concentration. For brewery fermentation chillers targeting 25–27°F setpoints, 35–40% PG is standard. Use our dilution calculator for your target temperature.
Can I use industrial-grade PG in my food plant?
No. If there is any possibility of incidental food contact — even through a heat exchanger leak — you need NSF HT1 certified product at minimum.
How often should I replace the glycol?
Every 2–3 years, or sooner if testing shows pH below 7.5 or depleted inhibitor levels. Test annually with a refractometer.
What water should I use for dilution?
DI (deionized) water only. Never use tap water (minerals degrade inhibitors) or RO water (too corrosive for system metals).
