A very interesting proposal for different varieties of oil and not only are multi-compartment tanks (two or three independent compartments). In this case, the savings of cost and space are compared to two or three tanks of the same capacity. Their roof and bottom are conical and based on stainless steel legs. They are manufactured in various dimensions with a total capacity of up to 45cm3. In this type of tanks, there is the possibility of controlling the temperature of the product by installing a cooling-heating jacket. The construction material of these tanks is stainless steel type AISI 304 with internal finish 2B 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.
