Collection — Unitank conical fermenters

Unitank conical fermenters.
At every scale you brew.

The Unitank is Bräu Supply's standalone fermenter — jacketed, pressure-capable, sanitary tri-clamp throughout. Same vessel that ships inside our BräuPro brewhouses, sold on its own to pair with any tri-clamp hot side, double your fermentation capacity, or replace whatever plastic conical, carboy bucket, or band-heater compromise you're still tolerating. Three scales: homebrew 5G–20G, 1 BBL pilot, and 3–5 BBL production.

What makes a Unitank

A vessel built to do every cold-side job — well.

Same architecture across every scale. The geometry, the fittings, the pressure rating, the standard tri-clamp ports — these don't change when you move from 10G to 1 BBL. What changes is jacket coverage, controller, and how much beer comes out the bottom.

01

Pressure-capable to 30 PSI

Spund, carbonate, and closed-transfer to keg without ever exposing the beer to air. No more siphons, no more bottling-bucket oxidation, no more lager that tastes like cardboard after week three.

02

True 60° conical bottom

Trub falls to the apex. Dump it through the butterfly valve after cold-crash. Harvest clean yeast for the next batch. No racking off the trub bed, no fermenter-shaped sediment cake.

03

Dimpled cooling jacket

Tap water for ales. Glycol for lagers and any temperature below ambient. The jacket holds set point within ±0.5°F across a 14-day fermentation — no band-heater swings, no fermentation chamber required.

04

Standard tri-clamp everything

1.5", 2", and 3" tri-clamp ports. No proprietary fittings, no shop-only spares. Replacement gaskets at any homebrew store, every valve serviced with a 9/16" wrench. The vessel is repaired, never replaced.

Pairs with any tri-clamp hot side

Bring your own brewhouse.

The Unitank is a standalone fermenter. It doesn't care how the wort got there — pour it in cold, or land it via tri-clamp from any compatible kettle. Common pairings on the Bräu Supply side:

Three sizes. Same architecture.

Match the Unitank to your batch size — or to the brewhouse you already own. Architecture, fittings, and parts are constant across the lineup; what changes is jacket coverage, controller, and capacity.

Why the Unitank

Designed around how fermentation actually works — not around what's cheap to fabricate.

01 · Vessel design

Dedicated, not compromised

The Unitank exists to ferment beer. It isn't a kettle that someone bolted a thermowell onto — the conical bottom, jacket, ports, and pressure rating were sized for the fermentation use case from day one.

02 · Temperature

±0.5°F across a 14-day lager

A dimpled body jacket gives even, full-body cooling. Pair with glycol and a controller and you get rock-stable set points across the longest cold-side beers you'll ever make.

03 · Pressure

30 PSI · spund and transfer closed

Carbonate naturally during the tail end of fermentation. Push finished beer to keg under CO₂ without ever exposing it to air. Beer that tasted right on Day 14 tastes right on Day 90.

04 · Trub & yeast

Dump · harvest · move on

Conical bottom + butterfly valve = trub leaves cleanly, yeast harvests cleanly, and the next batch's pitch is sitting in a sanitized jar by Sunday afternoon. No racking, no second-vessel hop.

05 · Fittings

Standard tri-clamp throughout

1.5" and 2" tri-clamp at every port. Off-the-shelf gaskets, off-the-shelf valves, off-the-shelf spares. Nothing about owning a Unitank means waiting on a single-supplier part.

06 · Scale

One architecture · three scales

Learn the workflow at 13 gal. The 1 BBL and 3–5 BBL builds behave the same — same ports, same hardware, same cleaning regime. You scale your vessel, not your process knowledge.

One architecture · three scales

Start small. Scale without rebuying the workflow.

Every Unitank uses the same fittings, same cleaning regime, same valve hardware. The vessel grows; the process you learned doesn't.

Step 1 · learn the workflow

Unitank questions

Common questions.

Do I need a BräuPro to use a Unitank?+

No. The Unitank is a standalone fermenter. It pairs with any tri-clamp kettle — our BräuPro and Unibräu brewhouses, your existing HERMS or RIMS, or someone else's pilot system. The only thing the Unitank cares about is that wort can get into it; how that wort got made is your call.

How is this different from a Spike, Ss BrewTech, or plastic conical?+

Three things.(1) It's jacketed.Most homebrew conicals manage temperature with an immersion coil sitting inside the beer — one more thing to clean and sanitize, cooling from a single spot instead of the whole wall, and hardware in the way of your trub dump and yeast harvest. The Unitank's dimpled jacket cools from outside the vessel; nothing inside but beer.(2) Rated to 30 PSI working pressure— spund, carbonate, and closed-transfer to keg without ever exposing the beer to air.(3) Standard tri-clamp at every port, and it's the same vessel that ships inside our commercial pilot systems — the architecture you buy at 13 gal scales to 1 BBL without changing your process. Coming from Ss Brewtech? See our Ss Brewtech Unitank alternative page for a side-by-side.

Tap water cooling or glycol — which do I need?+

Tap water works for ales fermenting at 65–72°F if your tap is cold enough year-round — which it isn't, for most of North America in summer. Glycol is required for lagers, cold-crash, and anything where your set point is below ambient. Most homebrewers add a glycol chiller within the first year. We sell a matched BEF-02 glycol kit on the parts page.

Can I run two batches on one BräuPro?+

Yes — that's the most common second-purchase pattern. Brew on Saturday, ferment in Unitank #1, brew the next batch the following weekend, ferment in Unitank #2. The BräuPro brewhouse runs back-to-back at whatever pace you want; only the fermenters are the throughput bottleneck. Add a second Unitank in the same size class and you've doubled your output.

What's the warranty?+

2 years on the stainless: the vessel, every weld and TC port, grain baskets, brew tables and stainless fittings.

1 year on electronics: controllers, pumps, heating elements, solenoid valves and temperature probes, whether they come with a system or are bought on their own. Not covered on elements: 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.

Gaskets, clamps and O-rings are consumables; replacements are in stock and cheap. Warranty replacement parts are free, and we bill the shipping at cost. If we need the faulty part back, we send you a prepaid label.

Lifetime parts support on everything we build — serviced, not replaced. Orders placed before October 8, 2026 keep the warranty terms they were sold with.
