- 54 W/sq in watt density supports fast thermal response
- 321 stainless steel sheath resists high-temperature corrosion
- +/-0.002 in diameter tolerance ensures precise fit
HVAC cartridge heater for industrial use
This Tempco swaged cartridge heater delivers 1,000 watts at 240 volts with a watt density of 54 watts per square inch. It suits industrial heating tasks such as moulds, dies and platens where precise, high-temperature output is required.
Replaces worn or lower-density cartridge heaters
The unit upgrades from heaters that cannot reach 1,400 degrees Fahrenheit or that lack the +/-0.002 inch sheath tolerance needed for tight fits. The jump is worth it when processes demand consistent heat transfer and longer service life in stainless-steel sheaths.
Verify voltage, diameter and mounting clearance
Confirm the 240-volt supply matches your circuit and that the 5/8 inch diameter meets the bore tolerance. Ensure the 10-inch overall length and 10-inch lead length suit the available space and wiring route before ordering.

Questions about this item
What hole diameter does the 5/8 in heater need for a precision fit?
The sheath diameter is 5/8 in with a tolerance of +/- 0.002 in, so the mounting bore must match that range for proper contact and heat transfer.
How are the 10 in leads connected to a 240 V supply without damaging the internal swaged junction?
Route the leads so they do not bend sharply at the heater exit, secure them away from the 1,400 °F sheath surface, and terminate on a circuit rated for 1,000 W at 240 V.
When should the 321 stainless steel sheath be inspected or the heater replaced?
Inspect the sheath for discoloration, scaling or distortion after extended runs at 1,400 °F; replace the unit if the sheath shows pitting or the 54 W/sq in density drops below spec.
