Erema Silicon carbide (SiC) electric heating elements for element temperatures up to 1600°C, available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment Sic heating elements are refractory, non-metallic products of round section or tubular form of a uniform diameter throughout their length Erema Sic heating elements, are manufactured from high-purity, recrystallized Alpha silicon carbide, and have earned the reputation as the world’s leading Sic heating elements. These elements are widely used as high-temperature heat sources for electric furnaces and for the firing of ceramic capacitors, ferrites and other electronic components that are commonly used in mobile phones and computers.

Sic heating elements are capable of high power output, and may be mounted either vertically or horizontally. Because the element material remains rigid even at the maximum operating temperatures, no special supports are required, which simplifies the design of the equipment?

  • Maximum element operating temperatures 1600 - 1650°C
  • High density element surface power loading (15W/cm2), approximately 5-10 times the output of Nichrome wire
  • High Mechanical strength throughout their operating temperature range
Excellent Thermal shock resistance
  • Chemically stable
  • Heat source is free of noise and air pollution
  • Various coating products are available for protection against water vapour and harmful gas atmosphere
  • Easy to handle and install
No need for complex support systems - Sic is self-supporting
  • Higher density resulting in longer life
  • Wide variety of shapes available
