Information

MPI Morheat has an extensive Stock List of Cartridge heaters available for same day shipment. MPI Morheat also manufactures custom cartridge heaters and can expedite production if needed.

Cartridge heaters are most frequently used for heating metal parts through insertion into drilled holes. For easy installation, the heaters are made slightly undersized relative to their nominal diameter. The majority of applications do not require maximum watt/in². Using as little wattage as possible to meet process requirements will ensure maximum heater life.

Holes should be drilled and reamed, rather than drilled to the final diameter with a general purpose drill. At high watt densities, a close fit is important. The fit is the difference between the minimum diameter of the heater and maximum diameter of the hole.
