Our Uni-Fermenter is constructed out of a brand new 26 Gallon (100Liter) Stainless steel keg, measuring 44" Tall. All fittings and legs have been professionally TIG welded and re finished. The Uni-Fermenter features a 4" Sanitary tri clamp fitting on the top of the keg, to access the interior of the keg. The removable 4" tri clamp plate contains both liquid and CO2 cornelius soda keg disconnects, as well as a safety pressure relief valve. The soda keg liquid out fitting has a dip tube that is a 1/2" off of the bottom of the fermenter and can be used to rack out the beer under CO2 pressure for kegging, as well as for serving. During fermentation, CO2 blow off is accomplished by removing the C02 connecter body fitting, and removing the poppet seal from the connector body. Next the connector body is sanitized,and re-installed without the poppet valve. Then a supplied FDA silicone 5/8" hose is attached to the female fitting, and run down into a bucket of water to serve as an airlock, and to catch any beer blow off. Once fermentation has stopped the blow off tube is removed, along with the C02 connector body fitting. The poppet valve and connector body are then sanitized, and re-installed prior to pressurizing with CO2 for conditioning, serving, or racking.The bottom of the fermenter features a 1.5" TC clamp fitting connected to a 3/4" NPT stainless ball valve for harvesting yeast and easy cleaning. The Uni-Fermenter has 3 welded Stainless Steel legs, with swiveling, lockable casters, that can quickly be removed by unthreading the wheel from its leg that contains a welded in, threaded insert. This allows you to shorten the overall height of the unit by 3" making it possible to fit into most common refrigerators. The Uni-Fermenter comes with all parts pictured.
