Cartridge Heaters Manufacturer and we provide tube-shaped, heavy-duty, industrial joule heating elements (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Cartridge Heaters provide superior heat transfer with uniform temperature and resistance from oxidation and corrosion at high temperatures. Our popular Cartridge heaters are the following design styles:
➤ Right Angle,
➤ 90 Degree,
➤ Posts out Both Ends,
➤ Post on Same End,
➤ Distributive Wattage.

History of Cartridge Heaters:
CARTRIDGE TYPES –
Original old standby made with ceramic supported wire insertion into a metal tube filled with loose fill inorganic ceramic powder (usually magnesium oxide). Cross sections can be round from 1/8 inch diameter to 2 inches diameter; square, hexagon, triangular, etc. Cross sections are also available; length can be from < 1 inch to > 4 feet.This is usually the first choice consideration for OEM’s and accounts for an estimated 20% of total electric heaters made. Power density is < 100 watts per square inch and temperature up to 1200 degrees F are possible.
- Standard Cartridges – Usually made inside a metal tube that looks like a bullet Cartridge; a possible source of its name. Various types listed below.
- Compacted Cartridges – Developed about 60 years ago, possible influenced by the good power density capacity of roll compacted tubular, said units by nature of compacting the inorganic power tightly to the resistance wire makes an excellent unit. Compacted cartridges power density increased compared to un-compacted cartridges in units less than 500 watts per square inch. Compacted heating units also can approach 1800 degrees F. The requirement for higher quality tubing (to withstand rolling/swaging compaction), precision fired crushable ceramic internal parts plus the added compaction operation make this unit 1 ½ – 3 times standard cartridge cost. They are available from most vendors in diameters from 1/8 inch to 1 inch and length from 1 inch to > 3 feet. A first choice for OEM’s that need high power density/temp. inside a small envelope.
