Product Description
National Element, Inc. FINAT - 25057-1 Firebar Radiant Tube Heater Element, 49" Long
PN: FINAT - 25057-1
In 1974 National Element Inc. developed an element which converts fuel-fired furnaces to electric. Because the conversion involves inserting a round heating element into the old radiant tube without any other alterations to the furnace, it requires no transformer.
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.
