Fully Loaded Out of the Box

The X3 arrives completely equipped with professional-grade features, eliminating the need for costly upgrades down the road:

• Built-in External Cooling Jacket featuring 1.5" Tri-Clamp ports.

• Neoprene Insulation Jacket for optimal thermal performance.

• Pressure Pack Lid equipped with a floating dip tube, draft-style quick-disconnect fittings for sampling and serving, and an extra 1.5" Tri-Clamp port designed specifically for hop bongs.

• Clear Flex Chamber Bottom Dump to visually monitor fermentation, drop and remove trub, and utilize integrated ports for purging, oxygenating, and carbonating.

• Flawless 304 Stainless Steel Construction finished with a premium mirror-polish inside and out.

• Professionally Ground and Polished Interior Welds for ultimate sanitation and easy cleaning.

What’s New in the X3 Design

• 8-Inch Tri-Clamp Lid: Replaces cumbersome, complicated band clamps with a secure, rock-solid seal that still provides plenty of clearance for manual cleaning.

• Four-Leg Reinforced Base: Flares out to create an exceptionally stable foundation, eliminating the tippiness common in three-legged units and providing unhindered access to front fittings and the dump system.

• Professional Horizontal Cone Ports: Mimics commercial brewery tanks by positioning the racking arm, carb stone, and thermometer horizontally. This allows for smaller minimum batch sizes and superior carbonation.

• 3-Inch Oversized Bottom Port & Butterfly Valve: Paired with the 3" Tri-Clamp Flex Chamber collection vessel for effortless management of heavy dry-hopping.

Deep Dive: Key Features

External Cooling Jacket

Temperature control is crucial, and an external cooling jacket hits the sweet spot. Unlike internal cooling coils—which are difficult to clean and struggle with cold-crashing in warm environments—the X3 jacketed design delivers maximum chilling power with zero compromise to your sanitation routine.

8” Tri-Clamp Top Port

The massive 8-inch opening lets you easily reach inside the conical for manual cleaning if desired. The unique three-piece Tri-Clamp ensures the top seals securely and handles pressure with ease.

Extra-Large 3” Tri-Clamp Dump Valve

Designed for heavy hop-headers. With a massive 3-inch bottom port, you have all the clearance needed to drop heavy dry-hop additions without clogging. The smooth mirror-polish interior walls allow flocculating yeast to slide effortlessly down into the cone, integrating seamlessly with the included Flex Chamber Collection Jar.

Reinforced Four-Leg Foundation

Conicals need stability, especially when mounted on casters. The X3 features a professional, four-leg welded-bar reinforced base that stands rock-solid right out of the box—no extra bracing shelf required. The added height also provides generous clearance underneath for elbows, sight glasses, or the Flex Chamber.

Adjustable Feet & Mobility

Comes standard with heavy-duty, thread-in adjustable feet to level the fermenter on uneven brewery floors. These can easily be swapped out for rolling casters whenever you need to glide the unit across the floor.

Flex Chamber Collection Jar (Trub Separator & Yeast Harvester)

Developed in collaboration with KegLand, this crystal-clear Tritan chamber attaches directly to the butterfly dump valve.

• Visually monitor fermentation activity.

• Remove trub and harvest clean yeast.

• Use threaded side ports with ball-lock adapters to inject oxygen, flush with CO2, or introduce adjuncts.

• Cap it off and store harvested yeast directly in the refrigerator for your next brew day.

Pressure Pack with Clear Float Technology

Ferment, carbonate, and serve from a single vessel. The floating dip tube draws beer from the top down, ensuring you always pull the clearest, sediment-free sample or transfer. Drawing samples under pressure also eliminates the oxygen exposure common with traditional sample valves.

Additional Features You’ll Love

• Downward-Facing Blowoff U-Barb: Prevents tubing kinks and makes cleaning much simpler than fixed stainless designs.

• Single-Piece Molded Silicone Gasket: Ensures a tight seal paired with a stainless steel lid clamp.

• Dual Cone Ports: Two additional 1.5" Tri-Clamp ports added to the cone and body for maximum flexibility with current and future accessories.

Available X3 Accessories

• Pressure Fermentation Kit: Required to safely ferment or seal an active batch under pressure. Includes a commercial-grade spunding valve, a sealed pressure gauge, a dedicated 15 psi PRV, and Foam-Axe to manage Krausen. (Note: The standard built-in PRV is not rated to handle active fermentation clogging risks).

• Hop Bong Oxygen-Free Dry Hopping Device: Purge oxygen from up to 6 oz of dry hops using CO2 before dropping them cleanly into your fermenter.

• High Roller Caster Set: Heavy-duty wheels to give your fermenter complete mobility around the brewery.

• IceMaster Max 2 & Insulated Tubing Kit: Perfect pairing for precise glycol temperature control, cold crashing, and quick-disconnect "dry break" lines.

• Immersion Heater: A low watt-density 2" Tri-Clamp heating element that gently warms your beer without scorching, ideal for cold climates or sensitive ale/kveik strains.
