(79) Watlow’s 375 finned strip is constructed of highly compacted MgO-based insulation, which conducts heat efficiently from the nickel chromium element wire to the sheath. Two-inch wide (51 mm) aluminized steel fins are attached in a way that maximizes surface contact so heat is transferred into the air faster. Lower sheath temperature and element life are all maximized by this finned construction.
(44) Composed of aluminized steel fins press fitted to a one-inch single-ended FIREBAR® element. The FINBAR™ 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 its finned construction. Installation is simplified by terminations exiting at one end and mounting accommodations on both ends.
