CONSTRUCTION
1. Seamless stainless steel sheath
2. Post terminals
3. Ceramic element support
4. Element wire situated close to
outside surface for maximum heat
transfer and minimum internal
temperature while preserving good
dielectric qualities
5. Magnesium oxide packing
6. Aluminum fins offering maximum
radiating surface and providing for
rapid heat transfer to the surrounding
medium. Stainless steel fins are
available for corrosive environments.
Aluminum fins are standard.
