Stainless steel fermentation tanks for wine are equipped with cooling jackets so that the temperature of the juice drops and is stabilized at the desired level. There is a choice between the base with slope or based on INOX legs and the bottom either closed or open with a floating lid. They are also manufactured from 1.0 m3 in various dimensions depending on the needs of the space in which they will be placed. The construction material of these tanks is stainless steel AISI 304 / 316 with internal finish BA (Mirror) and external Fioretto, with certificates of chemical analysis from the steel mill. The weldings are done with the Argon Tig method in a protective atmosphere of high-purity inert gas.
