Air HeatersFinned HeatersFINBAR Single-Ended HeatersComposed of aluminized steel fins press fitted to aone-inch single-ended FIREBAR element. The FINBARis designed to improve heat transfer to the air and permitsputting more power in tighter spaces—like forced airducts, dryers, ovens and load bank resistors.Heat transfer, lower sheath temperature and element lifeare all maximized by its finned construction. Installationis simplified by terminations exiting at one end andmounting accommodations on both ends.Performance Capabilities• Watt densities up to 50 W/in 2 (7.7 W/cm 2 )• 304 stainless steel sheath temperatures up to1200°F (650°C)• Voltages up to 480VAC• Amperages up to 48 amperes per heater or16 amperes per coilSlotted EndAluminized Steel FinsFlexible Lead WiresSS Mounting Bracket304 SS SheathFeatures and BenefitsRugged aluminized steel fins• Provides an increase in surface area to approximately16 square inches for every linear inch of elementlength.
