This 500L conical fermenter is built for breweries that need consistent fermentation temperature control without oversized capital equipment. The glycol jacket surrounds the cone and straight wall, which gives you uniform cooling across the entire vessel—not just the top section like some budget tanks.

We fabricate the fermenter from SUS304 stainless steel with a 2B finish on the interior and a brushed exterior. For brewers producing highly acidic or chloride-heavy products, we can upgrade to 316L on wetted surfaces. All welds are full penetration, and interior welds are ground smooth to prevent bacterial harboring. The vessel is designed for a working pressure of 0.15 MPa, with a safety valve set accordingly. That means you can crash cool and carbonate in the same tank without worrying about overpressure.

The cone angle is 60 degrees, which is the practical standard for yeast collection. A butterfly valve at the bottom gives you clean yeast dumping or trub removal without opening the tank. The glycol jacket is divided into two zones—one on the cone, one on the straight side—so you can adjust cooling based on where the exothermic activity is happening. During peak fermentation, the yeast generates heat in the middle of the tank; the side jacket handles that. When you cold crash, the cone jacket pulls the temperature down faster for clearer beer.

For cleaning, the tank comes with a spray ball that covers the entire interior surface. CIP solution circulates through the spray ball and drains out the bottom valve. We also include a sample valve at a height that lets you pull wort without disturbing the yeast bed. The pressure gauge and thermometer ports are tri-clamp compatible, so you can install your own instrumentation if you have a preferred brand.

Frequently Asked Questions

What batch size suits a 500L fermenter?
If your brewhouse produces 300–400L per batch, a 500L fermenter gives you headspace for krausen and CO2. For 500L batches, you would need a 600L tank to leave room for foam and yeast.

Why is the glycol jacket necessary?
Without active cooling, fermentation temperature can rise 5–8°C above your target, producing off-flavors like banana or solvent. The jacket lets you hold a precise temperature profile from pitch to cold crash.

Can I use this tank for both fermentation and bright beer storage?
Yes, because of the pressure rating and the smooth interior. Many small breweries use one tank for fermenting, crashing, and carbonating to reduce tank count.

What should I prepare before requesting a quote?
Tell us your batch size, beer type, number of fermentation tanks, and available floor space. Also mention your glycol chiller capacity—we can calculate the cooling surface you need. If you have a specific CIP setup or valve preference, include that too.
