Finned Tubular Heater

Finned tubular heaters are widely used in application which requires forced convective heating of air or gases at low to medium temperatures. Heaters are made up of tubular heating elements equipped with aluminium steel fins brazed, crimped or welded to the sheath. They are more efficient than tubular heaters since fins greatly increase surface area, permit faster rate of heat transfer to air, and thus higher wattage levels are achievable in the same flow area. Due to increased heat transfer rate, it maintains lower element surface temperatures resulting in increased heater life. Mechanically bonded continuous fins assure excellent heat transfer and help prevent fin vibration at high air velocities.

These industrial heating solutions are among the most common heaters and are best suited for a large number of applications such as conduction, convection, and radiation for stoves, industrial ovens, drying cabinets, air conditioners, etc. They can be used in virtually every industrial environment up to about 750°C (1382°F) and be molded into many unique and complex shapes. Finned heaters are extremely rugged, have low capital costs, and require negligible maintenance.
