Cylindrically-conical fermentation tanks with simplified design. The fermenters are equipped with a cooling jacket. Low-pressure vessel (maximum allowed pressure : 1.2bar). The cone fermentors are designed for both the primary fermentation process and secondary fermentation process (the maturation) of beer, cider or wine. They are not designed for the high pressure maturation process, beverage filtration process, filling beverages into kegs or the maturation process under high pressure.
