Finned Tubular Heaters
Finned Tubular Heater is a type of Finned Heaters, which is the most versatile, dependable and rugged of any heat generating device. These qualities make Finned Tubular Heating Elements an ideal heat source for many applications. Finned Tubular Heating Elements are the core of the most common heating solutions found today.
Finned tubular heaters are normally used for forced convection heating with outlet air temperatures of 300 C (572 F) or less. Steel finned heaters are standard with surface temperatures limited to about 425 C (797 F) compared to 815 C (1500 F) for an alloy sheathed non-finned heater. If a high surface temperature and the high radiation heat transfer that accompanies it is not detrimental to the remaining system components, a finned heater may prove to be the more economical choice. Some applications require stainless steel materials for corrosion resistance. The most efficient finned heaters are made with steel sheath and steel fins. Keep in mind that stainless heaters with stainless fins are very inefficient since the heat transfer rate of stainless is less than one quarter of that for steel.
