Heating Element
HE-Rod Ceramic Rod Heating Element
Ceramic-sheathed rod elements for aggressive-atmosphere furnaces.
Rod-type ceramic heating elements encapsulate the resistance wire inside a dense alumina ceramic tube, providing mechanical protection and electrical insulation in harsh environments including salt baths, gas-carburising atmospheres, and rapid air-blast cooling cycles.
