Description

The new and improved 55L FermZilla brought to you by the critical minds and engineers behind the original Fermentasaurus Gen 1. Although the original Fermentasaurus was revolutionary at the time of its conception, there's always room for improvement. This is partly due to the strong community of Fermentasaurus users who have helped push for an improved conical unitank.

The FermZilla is the perfect option for brewers that want all the advantages of a conical fermenter without the price tag of a full blown stainless steel unit. It allows you to dump trub, harvest yeast, and with the addition of the 55L FermZilla Pressure Kit (available in both stainless and plastic), you can carbonate and serve – all in one vessel! The clear PET tank allows you to visually monitor fermentation activity and is pressure rated to 2.4 Bar (34.8 psi), which means you can ferment under pressure, reducing ester and fusel alcohols in your finished beer. This also gives you the ability to perform pressure transfers. If you prefer to move your finished beer to a keg or other vessel, you can do so with little to no oxygen exposure.
 
New and Improved:
1. Larger Dump Valve - 3" butterfly dump valve is more resistant to clogging from large amounts of trub
2. Larger Opening - 4.75" top port opening allows for easier cleaning
3. Less Headspace - more appropriately sized for 10-gallon batches. Purging the headspace of oxygen is easier and more effective.
 
What's Included:
  • FermZilla 55L Tank with Butterfly Dump Valve
  • Reinforced Stainless Steel Stand
  • Top Lid with PRV (35 psi)
  • 1000 ml Collection Container & Lid
  • 3-Piece Airlock
  • Graduation Sticker
  • Adhesive Thermometer
  • Strap Wrench
  • Spare Seals

Specs:

  • 55 L (13.2 gal) Total Volume
  • Pressure Rated to 2.4 Bar (34.8 psi)
  • Height in Stand - 40.1"
  • Height w/ Airlock - 43.5"
  • Tank Diameter - 13.9"
  • Diameter in Stand - 15.7"
  • Lid & Collection Container Ports - 28 mm PCO 1881 threads
  • Temperature Rating:
    • When not under pressure, do not expose to liquids above 131°F
    • When under pressure, do not expose to any temperatures above 95°F*

*Please note that the temperature rating for the FermZilla tank is lower when using it under pressure. When not under pressure, it is perfectly safe to transfer wort into the tank below 131°F or to use hot liquids below this temp for cleaning. When under pressure, make sure to keep your fermentation temperature below 95°F and keep the fermenter in an environment that is below 95°F ambient. This is especially important when fermenting with kveik yeast. These strains are known to ferment hot if no temperature control is being used. Exceeding the temperature rating may compromise the tank, leading to a shorter life span or sudden failure to maintain pressure. Even with proper use, we recommend replacing the tank every two years.

Please note: when using the FermZilla under pressure, you must perform a water pressure check to ensure your connections are leak proof. To do this, fill your FermZilla up with water, apply at least 15 psi pressure, and check for leaks around all caps and threads.  
 

Pressure Stress
If you use the FermZilla to ferment under pressure, or you use CO2 to pressure transfer or force carbonate your finished beer, it is very important that you conduct semi-annual inspections of your tank. Even with perfect care, the FermZilla tank may show signs of wear from pressure stress over time. We recommend visually inspecting your tank for stress creases or other signs of wear once or twice a year. A hydro test should be conducted every two years, even if no signs of wear are found. The process is simple:

  • Fill the tank to the brim with water
  • Replace the Red PRV with a Green PRV rated to 4.5 BAR or higher
  • Pressurize the tank to 4 BAR (58 psi)
  • Check for leaks, then replace the Red PRV when finished

If leaks or potential points of failure are found, replace the tank before you continue using pressure with your FermZilla.

General Care
Taking good care of your FermZilla begins with cleaning and sanitizing the unit before and after use. The tank is made from food-grade PET, which is beautifully clear, but can be sensitive to long soaks in cleaners and acid-based sanitizers. In general, we do not recommend leaving products like PBW or StarSan soaking in the tank for more than an hour. Extended soaks have the potential to degrade the PET material and shorten the lifespan of the tank.
 

 

Having Trouble Removing The Lid?
The easiest way to take off the lid is to undo the lid ring then use a screw driver or faucet wrench to lever the lid up as shown in the animated GIF below:

 

Kegland Part number: KL06842

NOTE: FermZilla tanks are marked with a manufacturer’s “expiry date”. This does not indicate that the tank is bad after this date; it simply indicates that a hydro test may be in order. 2 years after production and every 2 years after first use, it is recommended that the tank be hydro tested to ensure the tank is holding pressure. Hydro test instructions are available here. You will also need the D1072 Green PRV to perform the test. If you do not plan to pressurize the fermenter, the test is not necessary.

Used it 2 times and no problems. To tall to set on my counter so I had to siphon out my wort, a little slower, so looking for a shorter stand to put it on. Very easy to clean.

Ok so far, really made for people who pressure transfer
Assembly was ok. This is really meant to stay in one spot and not be moved around. I am not setup for pressure transfer but wanted something to do double batches. I need to make a better stand setup so I can get my finished product out easier and will probably need a pump to fill this.

Inherently poor design
I bought this conical FermZilla, because I loved the concept. However, the implemetation is inherently weak. This contraption has too many O-rings looking at it with my engineering hat on.
I might not have headed all the warnings, for instance to leak test and not to fill with warm/hot wort. However, everything was fine until the fermentation started to kicked-in two days after brewing. It leaked to the point that the fermenter was empty by the time I got home in the evening. I now have a smelly basement. This is too delicate for a hobbyist. I will switch to the FermZilla All Rounder.

Perfect companion for Brewzilla
I gave up homebrewing because it was too much work for an old fella. Fermzilla and Brewzilla made it possible and affordable to brew large batches faster and easier than ever before. I feel like I could brew all the time now.

Love it
Got this because of experience with one I already own. Easy set up. Fermentation under pressure for a cyser really cut back on how much time it needed to age. It was drinkable green. So I got a 2nd one. It's worth getting the stainless steel pressure kit.
Love this thing so much that I bought a 2nd on. Fermentation under pressure is the way to go.

Was great until last night when it violently exploded
I have brewed 3 times with the FermZilla, and up until now it has been fantastic. The engineering of the product is truly remarkable. If anything, it should have warnings that you should not tighten things to a normal degree. Everything fits superbly with minimum force. Unfortunately, that might have contributed to last night's explosion. I isolated the yeast harvester with the dump valve and was letting it finish settling overnight. (Disconnecting the yeast harvester makes a yeasty mess consistently.) At some point the yeast demonstrated their might and created so much pressure in this small vessel that it exploded, sending yeast across the garage and shards of ?polycarbonate? in a smaller blast radius. Fortunately, the 10 gallons of beer is still pristine and the garage smells great . . . for now.

DO NOT UNDERESTIMATE THE MIGHT OF YEAST! Do not close the dump valve for more than a few hours if there is yeast in the collector! The dump valve is truly air tight and water tight.
Beware the power of yeast. Pressure can be dangerous.

Arrived assembled just needed some minor tightening. A little disappointed that the plastic is not thicker but it serves a purpose just fine.
