The tanks for sparkling wine/champagne are built to endure an operating pressure of up to 3.0 bar / up to 6.0 bar respectively. For this reason, they have elliptical roofs and bottoms as well as reinforced material. The cooling inside them is done with high-performance jackets that cover up to 90% of the tank surface and the low temperature is maintained with the insulation placed on the outside. For evenly temperature distribution inside, a side agitator with an electric control panel is installed. Capacities begin from 1.0 m3 up to 150 m3 with dimensions corresponding to the requirements of the space on which they will place. The construction material of this type of tank is stainless steel AISI 304 with an 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.
