(SiC) Heating Elements
High-Temperature, High-Stability Heating Solutions
Asanjo Heating Systems supplies (SiC) heating elements designed for reliable operation at very high temperatures where long life, stable performance, and consistent heat output are critical.
Kanthal SiC elements are manufactured from high-purity silicon carbide, offering excellent thermal conductivity, oxidation resistance, and mechanical strength. These elements are widely used in industrial furnaces, kilns, and thermal processing equipment operating in oxidizing and neutral atmospheres.
Types of Kanthal SiC Elements
Kanthal SiC heating elements are available in multiple grades to suit different furnace designs and operating conditions:
-
Standard SiC Grade – for continuous operation up to 1500°C
-
High-Temperature SiC Grade – suitable up to 1600°C
-
Low-Resistance / High-Power Grades – for fast heat-up and high power density applications
Shapes & Configurations
Kanthal SiC elements are supplied in various shapes to match furnace layout:
These shapes allow flexible furnace design, uniform heat distribution, and easy replacement.
