Standard EREMA heating elements are manufactured using re-crystallized silicon carbide and suit a variety of applications, however they are limited in their ability to withstand chemical attack at elevated temperatures. (For instance at temperatures over 1300 degrees Celsius, with a low dew- point atmosphere, standard SiC element service life will be shortened by an extreme reaction with nitrogen.)

To overcome these issues, employing unique technology, TKK has developed a high density, high strength and very durable heating element – the EREMA Super SA. Radically different in material structure compared with conventional SiC heating elements the EREMA Super SA elements demonstrate many advantages most notably longer service life, resultant cost savings and the ability to operate at higher temperatures. Furnaces using EREMA Super SA elements have reduced maintenance costs with less down-time production losses due to element failure.

With the need to purchase fewer replacement elements and resultant increased productivity and furnace flexibility the EREMA SA is the obvious choice for aggressive atmospheres. This unique highly functional element is able to be used in applications up to 1600 degrees Celsius where conventional bar type SiC elements cannot. Environmentally friendly, the longer life of these elements saves resources and reduces industrial waste due to premature element failure and loss of product.
