Finned Tubular Heater
Finned Tubular Heater
Applications requiring forced convective heating of air or gases at low to medium temperatures frequently use finned tube heaters. Tubular heating elements with aluminum steel fins brazed, crimped, or welded to the sheath comprise heaters. Because fins significantly enhance surface area and allow for a faster rate of heat transfer to air, they are more efficient than tubular heaters. This allows for higher wattage levels to be achieved in the same flow area.
It prolongs heater life by maintaining lower element surface temperatures because of its higher heat transfer rate. At high air velocities, mechanically attached continuous fins assist reduce fin vibration and guarantee superior heat transfer.
Among the most popular heaters, these industrial heating solutions work best for a wide range of applications, including conduction, convection, and radiation for air conditioners, drying cabinets, industrial ovens, and stoves. They may be molded into a wide variety of intricate and distinctive shapes and are utilized in almost any industrial setting up to 750°C (1382°F). Finned heaters require very little maintenance, are very durable, and have cheap initial expenses.
