Tubular air heating elements

Finned elements

Finned elements

Tubular element with dia. 8.5 mm and 14 mm can be fitted with fins, stripped vertically on the element. The fins increase the radiating area and reduce the surface temperature on the element without sacrificing heat transfer. Alternatively, higher surface temperatures can be used to decrease the size of the element. The heating element can be manufactured with a connection at one end or two.
