Firebar Radiant Tubes

The electrical path of the Firebar® radiates outward from the central core providing effective heat for the full length of the radiant tube. The Firebar® design concept allows replacement of individual conductors without replacing the complete unit. 80Ni-20Cr heavy round rod conductors make Firebar® compatible for many different applications that need specialty alloys. Each circuit contains a thermocouple for control start up. Stock shipments include operating instructions, terminals, insulation, all internal connections, and, if necessary, a base plate for vertical operation.
