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.

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.
