Heating Element
HE-Ceramic Ceramic-Insulated Resistance Element
High-reliability ceramic lace elements for salt-bath and crucible furnaces.
Ceramic-insulated lace elements thread resistance wire through interlocked ceramic beads, providing a flexible, refractory-grade insulation that withstands aggressive furnace atmospheres. They are the traditional choice for salt-bath and pot furnaces where liquid salt contacts the element surface.
