ABSTRACT:
A metal honeycomb heating element is protectively mounted in an enclosure comprising a one-piece enclosure wall, the heater being supported between a circumferential support member and a circumferential compression ring attached to the enclosure wall. A diametrically balanced compressive force is maintained on the edges of the heating element by the compression ring and support, this force operating to significantly extend the life of the heater element under hot vibration. Heater slot separators and electrode feedthrough structures for extending the life of the heater element are also provided.
