The Watlow Finbar heater combines a one inch single-ended Watlow FIREBAR® flat tubular heating element press-fitted together with aluminized steel fins. The steel fins effectively increase surface area to approximately 16 square inches for every linear inch of element length drastically improving heat transfer to the air. Improved heat transfer allows the Watlow Finbar heater to put more heating power in tighter spaces – like forced air ducts, dryers, ovens, and load bank resistors.
Description
The Watlow Finbar heater combines a one inch single-ended Watlow FIREBAR® flat tubular heating element press-fitted together with aluminized steel fins. The steel fins effectively increase surface area to approximately 16 square inches for every linear inch of element length drastically improving heat transfer to the air. Improved heat transfer allows the Watlow Finbar heater to put more heating power in tighter spaces – like forced air ducts, dryers, ovens, and load bank resistors.
The unique design and geometry of the Watlow FIREBAR® heating element allows it to heat media from ambient temperatures faster than tubular elements, while using the same wattage and lower sheath temperatures. The rugged fins of the Watlow Finbar heater further improves upon these virtues. Installation of the Watlow Finbar heater is simplified by terminations exiting at one end and mounting accommodations on both ends.
By using Watlow’s FIREBAR® heating elements, the Watlow Finbar heater can generate watt densities up to 50 W/in2 and sheath temperatures up to 1200°F (fin temperatures up to 1100°F). A number of material and other options exist to make Watlow Finbar heaters suitable for nearly any application.
Watlow Finbar heaters are available in lengths from 10 to 48″ (other sizes available by special order) and feature a number of termination and mounting options. Lavacone seals protect the Watlow Finbar heater from moisture damage.
Heat transfer, lower sheath temperature and element life are all maximized by the finned construction.
Installation is simplified by terminations exiting at one end and mounting accommodations on both ends.
Watlow finned heaters are 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.
Applications for the Watlow Finbar Heater
