Silicon Carbide Heating Elements – Maltec-H Type SE

Standard EREMA heating elements are made from re-crystallized silicon carbide and are used in a wide variety of applications. For furnaces with a special atmosphere or where a volatile chemical may be generated during the heating process care must be taken with the element design and application. Aggressive and corrosive atmospheres may cause damage to the SiC structure, rapid oxidization, increased resistance and a subsequent decrease in element life – this process is called ageing.

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.

Applications

• Heat treatment of molten glass
• Heat processing atmosphere including water vapor
