Silicon Carbide Heating Elements – Maltec-H Type SDL

Features

  • Withstands as high as 1600 (surface temperature)
  • Generates high heat output per unit surface area, approximately 5-10 times the output of Nichrome wire.
  • High strength and excellent shock resistance.
  • Chemically very stable.
  • Heat source is free of noise and air pollution.
  • Various coating products are available for protection against water vapor and harmful gas atmosphere.
  • Easy to handle.
  • Standard: IEC 60675
Enquiry

This type has a non-heating element at the center of the hot zone to improve the temperature distribution in the furnace chamber by suppressing the temperature around the central part of the furnace. The same materials as in type E and F are used.
