On top of all the fully welded TC connections and the additional pro features. The Unitank gives the brewer the ability to quickly carb beer in under 24 hours using the carb stone, while precisely monitoring head pressure. Features that until now were only available on our Ss Brite Tank for home brewers. Then perform a true pressurized and closed transfer to a serving vessel, keg, counter pressure bottle filler, or canning machine. Closed transfers significantly reduce the chances of oxidation when compared to open transfers.
Higher pressure limits also gives the user the ability to filter beer directly out of the vessel into one of the aforementioned packaging methods. Lastly, a Unitank with the addition of a spunding valve also gives the brewer the ability to ferment under pressure, which is gaining in popularity. In that same vein, the brewer can use the final few gravity points left of active fermentation to naturally carbonate their beer instead of force carbonate. The added feature set and flexibility is why pro brewers use unitanks in their brewing and packaging processes.
For example, if you are a 10 gallon batch brewer that bottles or kegs beer, you can now ferment, fine, carbonate, and filter all out of the same vessel.
That very same process would require both a BME Chronical and a Brite Tank, since the BME Chronical cannot be pressurized.
There are some benefits to having a dedicated Brite Tank, but most brewers would typically jump from their Chronical, to a keg, and then to a bottle. That same process can cut out the use of a keg, and the user can now go directly to a bottle in one step after carbonating in the Unitank.
