For the parts in contact with the product, the standard version of  CRIOX is made of stainless steel AISI 316L (1.4404), but on request it can be made of other weldable materials, such as ALLOY C-22 (2.4602) and AISI 904L (1.4539).
The particular shape of the CRIOX System allowed also to realize successful versions with internal coating made of particular fluorine-polymer materials, characterized by a high resistance against products containing extremely corrosive substances (acids and bases).
The success obtained by these executions led Italvacuum to realize other versions with enamelled drying chamber, in which the application of a special enamel, consisting of alkaline boron silicates, on the steel support, makes the CRIOX chemically inert inside.
For these specific versions, the blades of the lump-breaking units are made of ALLOY C-22 (2.4602) or other materials compatible with the process.
