Composed of aluminized steel fins press-fitted to a one-inch single-ended FIREBAR® element, the FINBAR™ finned tubular heater is designed to improve heat transfer to the air and permits putting more power in tighter spaces—like forced air ducts, dryers, ovens and load bank resistors.

Heat transfer, lower sheath temperature and element life are all maximized by the FINBAR heater's finned construction. Installation is simplified by terminations exiting at one end and mounting accommodations on both ends.
