Product Description
Composed of steel fins press-fitted to a tubular element, the 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 electrc heating element's finned construction. For electric immersed tubular heater, installation is simplified by terminations exiting at one end and mounting accommodations on both ends.
