Food-grade glycol your auditor will accept.
Glycol chillers and fermentation jackets sit inches from your product. For SQF and BRCGS audits, the fluid in those lines has to be food-grade, and you need the paperwork to prove it. PGFG is NSF Registered, Category HT1, Reg. No. 169143.
Talk to a Brewing SpecialistWhat you're up against
- Non-food-grade glycol near product is an audit failure waiting to happen
- You inherited whatever glycol came with the chiller and can't document it
- You need rapid post-fermentation cooling without temperature swings
Most breweries buy glycol from whoever sold them the chiller, and can’t tell an auditor what’s actually in the loop. Sub-Frost fixes that with PGFG, an NSF Registered HT1 food-grade propylene glycol that ships with the documentation auditors ask for, blended to your exact concentration and delivered fast from Indiana.
The spec
PGFG is NSF Registered (HT1, Reg. No. 169143), built on GRAS ingredients compliant with 21 CFR Subparts 182 and 184, and shipped at any pre-mix from 25% to full concentrate to match your chiller's spec. NSF registration, TDS, and SDS are free to download whenever your auditor asks.
