Precision Heat : Miniature Cartridge Heaters

Miniature cartridge heaters are ideal for challenging heating applications where space is limited. Inserted into a metal die, platen or other type of processing equipment, they deliver precise and highly-efficiently heat transfer up to 648.9°C.

Cartridge heaters are available in three watt densities - 60, 300 and 550 watts per square inch and measure between 1/2" and 12" in length. Size, sheath allow, leads, terminals, wattage and volage can be customised to meet specific requirements. 
Micro-cartridge heaters are found in a diverse range of OEM industrial and commercial applications, including 3D printers, ink and label printers, gas monitoring equipment, mass spectrometers, semiconductor test equipment and medical devices.
