A typical heating element is usually a coil, ribbon (straight or corrugated), of strip of wire that gives off heat much like a lamp filament. When an electric current flows through it, it glows red hot and converts the electrical energy passing through it into heat, which it radiates out in all directions.
Most of our Keith high-temperature thermal processing systems are heated by one (or a combination thereof) of the following heating elements: 1  Metallic resistance wire (Kanthal, APM). 2  Silicon carbide elements. 3  Molybdenum disilicide elements.
