High Temperature Cartridge Heater - Thermal CorporationThe electric coil is encased inside of a metal sheath which is insulated with ceramic, mica, mineral or fiberglass material.
The type of insulation is based on the desired wattage and application for the heater. It is important to note that the insulation is a required component because contact between the heating coil and sheath could cause short-circuiting.
Cartridge Heating Element - Thermal CorporationSheaths can be constructed from a variety of materials including aluminum, copper, iron, nickel and stainless steel.
When installing cartridge heating elements there are a number of factors to consider such as proper wattage and the desired temperature you wish to achieve with the element.
Cartridge heating elements are utilized for various applications and industries such as food services, fluid heating, hot plates, semiconductors, shrink wrap machines, labeling machinery, die cutting, mold forming, packaging, hot stamping, sealing printing, plastic processing, rubber forming and much more.
Cartridge heating elements will often be inserted through a close fitting hole and will have a surface thermocouple or remote microcontroller. The amount of heat the element can provide is based on how much electricity is passed through the resistive component of the element, so this allows many types of cartridge heating elements to adjust their heating power for specific applications.
