Below is a list of Cartridge Heaters manufacturers from St. Louis, Missouri.

Cartridge heaters are small, cylindrical electric heaters used to provide localized or precision heat to materials and equipment parts in a variety of settings. Similar to immersion heaters, cartridge heaters are usually inserted into a material to heat the surrounding area; unlike immersion heaters, which are usually submerged in water or other liquids, cartridge heaters are inserted into small holes drilled in metal materials and parts that require internal heat. While capable of providing localized high temperature heating, cartridge heaters can also radiate heat throughout the interior of a material or product.
