Cartridge Heaters Features Applications And Selection
A cartridge heater has a cylindrical tube type construction with a metal sheath containing resistive electrical circuit enclosed inside with proper insulation. It is a heating element used in various industrial applications. This type of heater is designed in such a way that the diameter has a standard dimension that can slide into holes of metric drill sizes commonly ranging from 4mm to 20mm. The length may vary from less than an inch to a few feet.
Generally these heaters are used to heat up solids by the phenomenon of conduction. The heater is made to slide into the hole drilled into a mold containing the solid. Uniform heating is a desirable feature of these heaters.
