Typical applications
Characteristics
The heating coil is insulated from the encasing metallic tube by granular material (MgO).
The tube is compressed to a round, oval or triangular shape. Terminals may be at either end
or at one end of the element (cartridge type).
Recommended alloy
KANTHAL D in elements with sheath temperature <700°C <1290
° F.
NIKROTHAL 80 in elements with sheath temperature >700°C >1290
° F.
Wire: Normally 2-4 times the element surface load (wire surface load is not so critical in this
element type).
