Worried about pesky bacteria hiding in the cracks of welds in your conical fermentor? Or the sort of porosity you find in all welds, which can cause leaks? The Fermenator™ from Blichmann Engineering™ is the only weld-free interior fermentor on the market! Everything that touches your beer is heavy-gauge stainless steel or FDA-approved silicone. And the Fermenator's™ surface where the fittings penetrate are smooth, with no weld "ripples," so it's easy to clean and sanitize. Our optimized design, identical to hydraulic systems under thousands of PSI, is also guaranteed to be 100% leak-free. Even the lid seal can be fully immersed under pressure! Weld-free fittings give you the peace of mind that comes with clean, bacteria-free beer.

Easy-to-Clean Weld-Free Fittings: All fittings used for the bottom dump and rotating racking arm are stainless steel, high-quality industrial fittings. Because our fittings can be removed from the tank, they are easy to clean and replace as well as sanitize, boil or autoclave. Last, but not least, weld-free fittings allow you to orient the dump valve in any position you desire.

Rotating Racking Arm: The rotating racking arm is standard equipment, just like the huge conical fermentors used by craft brewers. This feature lets you start your siphon with the racking arm horizontal and rotate it slowly downward until you just start picking up yeast sediment – the best and only way to siphon clear beer! Using the racking arm prevents wasted beer or sediment in your kegs. This exclusive, revolutionary design utilizes stainless flare fittings, in which bacteria can't hide. The valve handle shows you the position of the racking arm at all times. 

Lid Hatch: This generously sized lid opening offers you easy, sanitary access to minimize exposure of fermentables to oxidation and bacterial contamination when dry-hopping or adding finings. It's also much easier to pitch yeast than pouring it through the small stopper hole.

Bolted Leg System: Our channel-shaped legs offer improved strength and appearance. An exclusive welding process is utilized to install fasteners on the tank wall, leaving the interior of the tank absolutely spotless and superior to TIG-welded designs in which weld distortion (rippling) is unavoidable. These legs can be replaced in minutes if they are accidentally damaged, and, most importantly, they are affixed to the tank so cleaning is much easier than if the tank simply sits on a stand.

Pressure-Capable Stainless Lid: Just like the big breweries, use CO2 pressure to pump your finished beer up to 6 feet above your fermenter to your kegs. This eliminates the need to elevate the fermentor above the kegs or bottling bucket. This is ideal for chest freezers but is not intended for carbonation.

Wine-makers: The sealing system is far superior to wine tanks and completely impervious to oxygen, forming a 100% pressure- and vacuum-tight seal so there's no need for a floating lid. Most stainless wine fermenting tanks have a loose-fitting lid for primary fermentation (to vent gas) and a floating lid for secondary fermentation (to prevent oxygen infiltration). This floating lid has an inflatable seal "tire" with a “bicycle pump” and must be checked periodically to be sure it hasn't deflated. It is also a source of bacterial contamination from fermentation material on the walls of the fermentor. During primary (alcoholic) fermentation the CO2 from fermentation blankets and protects the wine from oxidation.  After complete fermentation has been verified, simply apply a positive pressure of an inert gas like Nitrogen or Argon with a low pressure regulator to keep oxygen out.  During sampling and dumping the lees, the regulator will replace the drained wine and keep oxygen from entering.

Improved Lid Seal: An exclusive bead molded into the seal profile offers improved sealing on the tank lip and further protection of your fermentables from contamination. Its top-quality silicone material has improved bond strength for excellent sealing and temperature capability for long life. Plus, the softer material conforms better to the irregular tank surface for outstanding sealing capability far superior to all competitors.

Folding Handles: They fold neatly away when not in use and stay connected to the unit at all times!

The 27 and 42 gallon Fermenator™ cannot be moved when full due to the weight of the unit. When empty, all units are light enough to easily be carried by the handles.

Ultra Low-Profile Design: The Fermenator™ can easily be placed in a variety of full-sized refrigerator or freezer for maintaining fermentation temperatures. (See the Data tab for dimensions.) And check out the FAQ tab to learn how economical and easy it is to convert a freezer into the ultimate lagering chamber!

Leg Pads: Plastic leg pads protect your counters and refrigerator from scratches.

Leg Extensions: Optional bolt-on leg extensions raise the unit for easy transfer into a Cornelius keg. This is a great feature for taking the hassle out of racking your finished beer.
