To reduce this affect EREMA offer a range of protective coatings. These coatings, which are application specific, create a protective surface film that helps protect the Sic structure from chemical attack.
As an extension and refinement of this technology, and to further improve element performance, TKK have now developed the EREMA SE type for rigorous environments.
Recently developed, using technology unique to TKK, the SE type differs significantly from conventional SiC heating elements.
During manufacture, using material similar to the coating applied to standard EREMA elements, the SE type is infused to form a protect deposit throughout the Sic structure - not just on the surface.
This protective deposit in depth affords the SE type greater durability when used in aggressive atmospheres or where corrosive gases may be present.
