High Density Cartridge Heaters

Cartridge heaters provide precise and localized heating. It is known for extensive usage in the heating process industry. Cartridge heaters are put to use for heating a block of metal from the inside. These can be customized to achieve a particular watt density depending upon the requirements of the application. To make the process of installation convenient, the heaters are made slightly smaller than the nominal diameter.

How does Cartridge Heaters work?

The heater has a ceramic core covered by a resistance coil. The core is placed in a metal sheath. The heat caused upon receiving power leads the sheath to heat up. Cartridge heaters can work at different densities, be it low, medium, or high watt. The ideal temperature depends on the kind of application that it is used for. The heaters can function at a temperature of up to 1400°F. In the case of high-temperature applications of more than 1000°F, Incoloy sheathes are provided for better durability and heat transfer.
