Application Scenarios
Core Brand Fermentation – Primary ale/lager fermentation with tight ±0.5°C glycol control; ideal for flagships produced year-round
Cold Crashing & Lagering – Jacketed cone + cylinder holds sub-0°C for haze drop-out and extended cold conditioning
Uni-Tank Bright Beer Service – Pressure-rated (1.5–2.0 bar) for in-tank carbonation, clarification, and direct-to-keg/bottle/can transfer
Seasonal / High-Gravity Specialties – Extra headspace allows high OG batches (double IPA, imperial stout) without blow-off loss
Cellar Expansion Projects – Drop-in compatibility with existing racking arms, CIP returns, and glycol manifolds of standard North American / EU brewery layouts

Customizations: Shadow-less thermowell, carb stone, extra TC ports, pressure gauges in psi/bar, glycol inlet size to match existing manifold.
Key Features
Uni-Tank Versatility
Ferment, crash, carbonate, and serve from one vessel; reduces cellar footprint and cleaning labor
True Cone Cooling
Dedicated lower jacket prevents yeast-settling temperature variance, critical for lager clarity
Dead-Leg Minimization
Shadow-less welds, sanitary clamp fittings, no hidden crevices → lowers wild yeast/contamination risk
Dry-Hop Without O₂ Pick up
Counter-pressure dry-hop port keeps DO low during late additions (key for NEIPA/hazy IPAs)
Stackable Design
20 BBL tanks can be paired in banks sharing a single glycol header and CIP return line
Brewer-Friendly Ergonomics
Clearly marked sample valve position, accessible blow-off, leg leveling bolts for uneven floors
product Advantage
01
Flavor Consistency
±0.5°C glycol control preserves ester/phenol profile batch-to-batch, protecting brand identity
02
Reduced DO & Oxidation
Closed-transfer readiness + CO₂ purge ports protect delicate aromatics in hop-forward styles
03
Lower OpEx
CIP-optimized interior reduces caustic/sanitizer consumption; jacket design cuts glycol load
04
Scale-Ready
Matches 10–20 BBL brewhouse throughput (typical 2:1 or 3:1 FV:Brite ratio)
05
Regulatory Confidence
Full material certs (MTRs), pressure test reports, welding maps supplied for licensing
06
Quick ROI
Uni-tank function eliminates need for separate brite tanks in early-stage expansions

frequently asked questions
1
Q: Is a 20 BBL fermenter big enough for a small commercial brewery?
A: Yes. Most breweries running a 10–15 BBL brewhouse pair 2–4 × 20 BBL fermenters with 1–2 bright tanks. This covers ~2–3 brews/week and scales well as distribution grows.
2
Q: Can this tank be used as both a fermenter and a bright tank?
A: Absolutely. It's a true uni-tank — pressure-rated for in-tank carbonation and bright beer storage, eliminating the need for a separate brite tank in early-stage setups.
3
Q: Does the 20 BBL tank have separate cooling zones?
A: Yes. Sidewall and cone are independently jacketed and plumbed, allowing precise temperature gradients during fermentation and cold crashing.
4
Q: How do you prevent oxygen pickup during dry hopping?
A: The tank is equipped with a counter-pressure dry-hop port. You can purge with CO₂ before opening, keeping dissolved oxygen (DO) low — critical for hazy IPAs and pale ales.
5
Q: What glycol chiller capacity is needed for a bank of 20 BBL tanks?
A: Typically a 10–15 HP glycol chiller can handle 3–4 active fermentations + crash cooling simultaneously. We'll provide a load calculation based on your cellar layout.
6
Q: Is the tank compatible with US-standard tri-clamp fittings?
A: Yes. Standard TC sizes (1.5", 2", 3", 4") are used. We can also supply DIN or SMS fittings per your region.
