Description

This is a no compromise, professional level hardware kit that allows for safe pressure fermentation in an X-Series Uni Conical. If you plan to ferment, or to seal/cap an active fermentation, in your BrewBuilt X-Series Conical you must use this Brewbult Kit for Fermenting Under Pressure.  During fermentation Krausen can potentially clog the PRV that is built into the lid.  The hardware in this kit is the same as what you will find on a commercial Unitank. This is not an all-in-one unit. All-in-one units are cheaper but not as safe.

Component Break Down:

Commercial Grade Spunding Valve - The kit is built around a commercial Spunding Valve that allows you to set your desired fermentation pressure. if that ferementation pressure exceeds your set point, it will blow off any excess pressure from the X-Series Conical. The clear cup holds liquid acting as an airlock and allowing krausen to exit. The Spunding valve is also adjustable.

Pro Grade PRV (Pressure Relief Valve) - On all brewery pro tanks, a tri-clamp PRV is always installed in addition to a Spunding Valve. This is because a Spunding Valve still has the potential to clog. The pro PRV has a very wide interior body as to reduce the risk of clogging. The PRV is non-adjustable and comes preset to relieve pressure at 15 PSI.

Sealed Pressure Gauge - This is a liquid filled, sealed gauge. The bottom of the gauge is a thin plate of stainless that moves up or down in relation to pressure in the tank. That causes the oil in the gauge to compress which is what the gauge reads. When properly sealed, there is no way krausen can get into this gauge and cause a false reading. However, it is important to ensure the guage is sealed, otherwise, there is a risk that krasuen clogs the gauge giving you an inaccurate reading. 

Foam Axe - Foam Axe is a silica-based krausen cutter used by commercial breweries to reduce krausen blow off while increasing foam retention in your beer. Using Foam Axe is required for every batch fermented under pressure, but we recommend it for all batches fermented in your X-Series Conical. Foam Axe helps keep krausen out of PRVs and other hardware which is always a good idea.

When your BrewBuilt Uni is outfitted with a Kit for Pressure Fermentation there are three devices for relieving pressure, including the PRV that is always built into the lid, the adjustable Spunding Valve, and the pro grade PRV.  

Includes:

  • Commercial Grade BrewBuilt Spunding Valve
    • 1 BAR (0.3–14.5 psi)
    • Hand Adjustable Blowoff
    • 1.5" tri-clamp Connection
    • Made from 304 stainless steel with plastic liquid cup
  • Tri-Clamp Pressure Relief Valve (PRV)
    • Calibrated to 1 BAR (14.5 psi)
    • 1.5" tri-clamp connection
    • Made from 304 stainless steel
  • Sealed, Liquid Filled Pressure Gauge
    • Calibrated to 2 BAR (30 psi)
    • 1.5" tri-clamp connection
    • Made from 304 stainless steel
  • CellarScience Foam Axe Krausen Reducer
    • Reduces krausen build up inside the fermenter
  • Connection Hardware
    • (3) 1.5" T.C. Clamps
    • (3) 1.5" EPDM T.C. Gaskets

 

WARNING! The use of the BrewBuilt Kit for Fermenting Under Pressure is required for performing Pressure Fermentations in your X-Series conical. The PRV built into the lid is not designed to be the only release point during a pressure fermentation. 

WARNING! The use of Foam Axe is required to reduce krausen (foam from fermentation) production in the fermenter. 

WARNING! Always release pressure, then remove the PRV built into the lid to ensure the conical is completely depressurized before removing fittings or the lid clamp. Failure to do so can result in personal injury.

If the PRV is preset to 14.5 PSI, how does that work with the spunding that goes to 30 PSI????
Jon Brady on Jan 18, 2023
BEST ANSWER: Do not understand the question.

Tanks are rarely rated for more than 30psi, since it is unnecessary and much more expensive to qualify,
The PRV is set to a value, say 16psi. As pressure exceeds that, it opens slightly to allow a trickle (or more) of gas to escape, thus maintaining the desired pressure.

The spunding valve is NOT a PRV. ALL TANKS MUST HAVE SEPARATE PRESSURE RELIEF VALVES AND VACUUM RELIEF VALVES (or a combo unit).
What are the cleaning procedures for the PRV and spunding valve? Do they disassemble adequately for full cleaning and sanitizing?

BEST ANSWER: They are meant to be used in a scenario where you CIP, and they are "purged" during each of the steps of that process.
When cold crashing with this as the temperature decreases lowering volume creating negative pressure in the ferment or. Does one have to worry about drawing sanitizer through the spunding valve?
Calvin Fishburn on Jan 9, 2024
BEST ANSWER: The spunding valve is NOT a vacuum check valve; it will NOT normally allow intake. If the tank has no pressure and a user pulls the plunger handle, sanitizer from the cup WILL leak in - don't do that.

The spunding valve is placed on the tank before fermentation completes. So, it will already have some pressure when crashing begins. Thus, the contraction of the liquid is not be significant enough to cause implosion - but act accordingly AND ALL TANKS MUST HAVE PRESSURE RELIEF VALVES AND VACUUM RELIEF VAVLVES (or a combo unit).
