Applications & Where 300L Fermenters Fit Best

300L Fermenters Are Designed for Small Commercial Brewing Operations That Require Stable Fermentation Performance with Manageable Batch Volumes.

Brewpub Cellars & Taproom Fermentation
The 300L fermenter is well suited for brewpubs and taproom breweries that require reliable on-site fermentation without excessive production pressure. This capacity allows breweries to maintain steady beer rotation, run multiple styles in parallel, and reduce the risk of overproduction. The fermenter fits easily into cellar or back-of-house layouts while delivering professional-grade temperature control, hygiene, and pressure management.

Expanding Nano Breweries
For nano breweries growing beyond pilot-scale systems, 300L fermenters offer a practical step toward small commercial operation. Compared to 200L tanks, this volume provides more stable fermentation behavior and improved production efficiency, while keeping raw material cost and operational complexity under control. The tank design and cooling logic closely follow larger commercial fermenters, making future scale-up more straightforward.
Image description
Pilot Production & Limited Commercial Runs
The 300L fermenter is commonly used for pilot production and limited commercial releases. It allows brewers to validate recipes, yeast performance, and fermentation timelines under conditions closer to full-scale production, without committing to large batch volumes. This makes it ideal for seasonal beers, test-market products, and process optimization.

FAQ — 300L Fermenter (Engineering & Procurement)

Direct answers based on the 300L fermenter specification and typical project workflow.

Yes. The spec lists the tank dimension as customizable. The conical bottom angle is listed as customizable (standard 60°). The manway can be top-mounted oval as standard, with side-mounted available. Glycol inlet/outlet can be top or bottom design.

Tank and jacket working pressure is specified as < 0.2 MPa. A mechanical safety valve PRV 2bar/30psi is included (1bar/15psi available). A shock-proof pressure gauge is installed on the CIP arm. Optional: pressure adjustable bunging valve 0.2–2.2 bar for special request.

The interior is fully polished to 0.4 μm without dead corner, using sanitary 2B finish plus cleaning and passivation (8K mirror finish optional). CIP is supported by a 360° rotary spray ball and a CIP arm with valves.

The cooling jacket is dimple plate on the bottom and side wall. The design references 35% glycol liquid at -5°C. Glycol inlet/outlet ports use thick-wall pipe thread, and the port arrangement can be top or bottom design.

Share your project location (standards/voltage needs), quantity, preferred manway type (top or side), whether you need adjustable bunging valve, and your glycol loop connection preference (top/bottom port design). If you have a layout, we can align ports and piping to reduce site work.
