Take full control of your fermentation with the Fermenator™ G4 – Cooling System from Blichmann Engineering. Specifically designed for use with our Fermenator™ G4 Conical Fermenters, this system gives you precise fermentation temperature control — a key factor in producing consistent, high-quality beer, cider, and other fermented beverages. Built by brewers, for brewers, it’s the reliable solution your fermentation process needs.
Designed for Performance and Cleanability
The heart of this fermenter cooling system is a 304 stainless steel cooling coil. It’s easy to clean, resists corrosion, and is made for long-term use. The coil features max flow technology to keep your cooling liquid circulating smoothly and evenly, improving chill efficiency and stability. A tri-clamp port makes setup fast, secure, and sanitary — just clamp it into place and connect your chilling lines.
Whether you’re lagering at 50°F or keeping an ale steady in summer heat, this system gives you pro-level temperature control in any season. It works seamlessly with glycol chillers or other cooling setups, making it a flexible solution for both homebrewers and pilot-scale pros.
Fits All G4 Fermenter Sizes
We offer four models of the Fermenator™ G4 – Cooling System, each tailored to match our fermenter lineup: 7-gallon, 14-gallon, 19-gallon, and 1 BBL. The 1 BBL model is especially popular with startups and nano-breweries for its reliable performance and scalability. Whether you’re just starting out or scaling up, there’s a fit for your fermenter.
