Vessel only or + Conditioning Kit?
The 1 BBL Unitank ships pressure-ready as a vessel. The Conditioning Kit adds the four accessories most owners buy in the first six months — everything you need to naturally carbonate, force-carbonate, dry hop oxygen-free, and run closed-loop sanitation. Commercial-standard hardware throughout.
Which chiller fits this Unitank?
Tap water won't hold this vessel in summer. The 1 BBL needs a dedicated glycol chiller — the MCED BEF-05 is the matched chiller for 1 BBL operation. Add the temp control kit if you have your own chiller, or the kit plus a BEF-05 chiller if you don't.
Six stages. One vessel.
Same workflow as the homebrew Unitank, scaled to 1 BBL volumes. Pressurized phases (steel-tinted) happen above 5 psi — the spunding valve and PRV manage the loop.
Fill
Transfer chilled wort through the side tri-clamp manway. Pitch yeast. Seal.
Ferment
Primary fermentation at set point. Glycol jacket holds temperature; CO₂ vents.
Pressure
Switch to the spunding valve. Pressure rises through the tail of fermentation — 12–15 psi naturally carbonates the beer.
Crash
Drop to 32–35°F over 24–48 hours. Yeast flocculates to the apex. Pressure holds; no air ingress.
Harvest
Open the 2" butterfly trub-dump. Pull a yeast sample for the next batch through the sample port.
Transfer
Pressure-transfer carbonated beer through the 3" racking arm to brite tank or keg. Closed transfer — no oxygen, no flavor loss.
What's included
Same vessel that ships inside our BräuPro 1 BBL brewhouse — pressure-rated, fully tri-clamp, dimpled partial body jacket on the upper third for glycol cooling.
-
✓
1 BBL jacketed conical Unitank vessel 304 stainless · sanitary polish · pilot-scale conical bottom · dimpled partial body jacket on the upper third for glycol cooling.
-
✓
12" side tri-clamp manway with PRV port Pilot-scale side manway with a PRV tee — fit your spunding valve, blow-off arm, or pressure gauge here.
-
✓
3" racking arm with sight glass Rotates to pull beer above the yeast cake. Sight glass lets you confirm clarity before pressure transfer.
-
✓
2" butterfly trub-dump valve Apex-mounted, larger than the homebrew Unitank's 1.5" version. Production-rate trub dump.
-
✓
Sample port Side-mounted tri-clamp sample valve — gravity, taste, infection check mid-fermentation.
-
✓
Glycol inlet/outlet (1.5" tri-clamp) Standard 1.5" tri-clamp jacket ports. Connect an MCED chiller with our glycol kit, or adapt to NPT hose or hard pipe with tri-clamp to NPT adapters.
-
✓
Tri-clamp hardware kit 1.5", 2", and 3" clamps, gaskets, and caps. No proprietary fittings.
-
✓
Drop-in volume ruler + blow-off arm Stainless ruler clips to the manway; blow-off arm routes to a sanitizer pail during primary.
*Vessel rated to 30 psi working pressure (2 bar). Set the spunding valve no higher than the PRV rating — 15 psi (1 bar) as shipped.

What to add for each extra tank
On a BräuPro 1 BBL, each extra Unitank 1BBL becomes the kettle for the next brew, then ferments that batch. The mash tun is shared. For each extra tank, add:
- 5500 W tri-clamp brewing element
- Stainless thermowell
- Rotating racking arm
- 3" butterfly valve, so one HopDrop moves from tank to tank
- Temperature control kit if you cool with glycol
About the 1 BBL Unitank.
Will I be charged anything at the border?+
No. Every US order ships fully duty-paid. We clear it and prepay the duties, tariffs and brokerage before it ships, and the courier delivers it like a domestic parcel. The price you see is the price you pay.
Our guarantee: if you're ever charged import duties or fees on a Bräu Supply order, send us the receipt and we refund them, no questions.
Alaska, Hawaii and international orders are quoted before you buy — contact us.
What's the build spec?+
Same vessel that ships inside our BräuPro 1 BBL brewhouse for the last two years — 304 stainless, sanitary polish, dimpled partial body jacket on the upper third for glycol cooling. Rated to 30 psi working pressure (2 bar). Pilot-scale conical bottom for clean trub harvest.
Do I need a BräuPro to use this?+
No. The 1 BBL Unitank is a standalone fermenter. Pair it with any tri-clamp hot side — our BräuPro 1 BBL, your existing pilot kettle, a commercial three-vessel rig. The only thing it needs is wort that gets to it cold.
Which glycol chiller should I pair with this?+
The MCED BEF-05 (4,440 BTU) is the matched chiller for 1 BBL operation — handles primary fermentation, cold-crashing, or two fermenters in parallel. For a 1 BBL hall running 3+ Unitanks, look at the BEF-075. We size for you on request.
Can I use tap water cooling on a 1 BBL?+
Tap water won't hold this vessel in summer. The 1 BBL's volume + thermal mass means tap water can keep up only when ambient is below ~55°F and you're fermenting ales above 65°F. For lagers, cold-crashing, or year-round operation, you need a glycol chiller. We don't sell a tap-water kit for the 1 BBL — it would be a setup for failure.
How do I clean a 1 BBL Unitank?+
Standard CIP procedure: cold rinse, hot caustic recirculation through the racking arm + butterfly, acid rinse, final rinse, sanitize. We sell a CIP spray ball that fits the 12" manway for closed-loop cleaning. Cycle takes ~45 minutes vessel-to-vessel.
What does shipping look like?+
Freight-only from our Vancouver, BC workshop. Ships in 5–10 days. Free shipping to the lower 48 — duties and import fees included at checkout. We palletize, you'll get a delivery appointment, and we'll talk you through inspection on receipt.
What's the warranty?+
2-year warranty on the vessel, every weld and TC port, and on the controller and pump where they're included.
Heating element: 2 years against defects. Not covered: dry-firing (running the element without liquid covering it), and heat or melt damage at the twist-lock plug from a loose or improper connection — a proper, fully seated connection has to be maintained.
Temperature probe: 6 months — it's a consumable. Gaskets, clamps and O-rings are consumables too; replacements for all of these are in stock and cheap.
Lifetime parts support on everything we build — serviced, not replaced.
