Fermentation Tanks
Cylindrical conical fermentation tanks sized to your weekly brew volume, with the cooling jacket and cone angle that decide fermentation consistency.
Key Specifications
| Working volume | 500 L / 1,000 L / 2,000 L / 5,000 L / 10,000 L / 20,000 L |
|---|---|
| Cone angle | 60 degrees standard, 74 degrees optional |
| Cooling | Dimple jacket, 2-3 zones, glycol inlet 2 degrees C |
| Working pressure | 1.5 bar standard, 3 bar optional |
| Material | 304 or 316L stainless, interior Ra ≤ 0.8 µm |
| Insulation | 80 mm polyurethane, stainless cladding |
| Fittings | CIP spray ball, racking arm, dry-hop port, sample valve |
Why the cone angle matters
A 60 degree cone lets yeast and trub slide to the bottom outlet without a manual push, which is what makes harvesting reproducible. A shallower cone is cheaper to build but leaves a yeast shelf that has to be washed out, and that shelf is where off-flavours start.
Cooling jacket layout versus fermentation curve
Two zones suit ales where the temperature profile is gentle; three zones give the control that lagers need during the slow diacetyl rest. Running glycol at 2 degrees C rather than -4 degrees C reduces the risk of icing the jacket wall and cracking the weld.
Pressure rating and carbonation
If you plan to carbonate in the tank rather than in a bright tank, specify 3 bar. At 1.5 bar you are limited to conditioning, and any attempt to force-carbonate will lift the relief valve.
Typical Applications
- Breweries matching tank to brew day — Plan roughly one fermenter per weekly brew plus one or two spares, so a stuck fermentation does not stop the brewhouse.
- Dry-hopped and sour programmes — A dedicated dry-hop port and a 74 degree cone for sours keep these beers off the main tanks.
- Breweries harvesting yeast — A racking arm above the cone lets you crop clean yeast and dump trub separately.

Frequently Asked Questions
How many fermenters do I need for a 1,000 L brewhouse?
Four to six for weekly brewing plus conditioning, assuming a 2-3 week turnaround per batch.
Can tanks be stacked?
Up to 2,000 L they can be stacked two high with a suitable frame, which halves the cellar footprint.
Is 316L necessary?
For standard beer, 304 is sufficient. Choose 316L for high-chloride water, sour programmes or where a customer audit specifies it.
