Unitank – 8 Gal (35L) Jacketed Conical Fermenter

8 Gal (30 L) Jacketed Unitank Fermenter

Compact, pressure-rated tri-clamp fermenter designed for ~5 gallon batches with professional cold-side control.

The Bräu Supply 8 Gal (30 L) Unitank is a compact, pressure-rated conical fermenter engineered for advanced homebrewers, pilot testing, yeast propagation, and small-batch R&D work. Built from sanitary 304 stainless steel at 1.5 mm thickness and rated to 15 psi, it delivers true pressure fermentation, closed transfers, and in-tank carbonation in a fully tri-clamp, serviceable format.

Working volume: Designed for a ~5 gal batch size (typical working volume). Maximum capacity is 8 gal (30 L).

Cooling: This model uses a fully welded glycol jacket on the cylindrical body (body-only jacket). The cone is not jacketed.


Temperature Control – Body-Only Glycol Jacket

The welded glycol jacket wraps the cylindrical body for efficient cooling without internal coils. This keeps the interior fully open for inspection and cleaning while providing stable fermentation temperature control using a glycol chiller or tap water where appropriate.


Pressure Fermentation & Closed Transfers (15 psi)

Rated to 15 psi (1 bar), the Unitank supports pressure fermentation, spunding, and oxygen-minimized transfers. This enables natural carbonation, reduced ester formation, and sealed transfers to kegs without oxygen exposure.


Sanitary Construction & CIP Compatibility

All product-contact connections are tri-clamp for sanitary serviceability. Smooth internal geometry and unobstructed access support manual cleaning and CIP spray ball use. No threaded fittings, no hidden crevices—built to real brewery sanitation standards.
