Introduction of finned air tubular heater
A corrugated metal fin is helically wound on a tubular element to improve heat transfer in air applications. Depending on the sheath and fin material selected, the fins are either permanently attached, mechanically or via furnace brazing. The entire assembly then goes through a computer controlled atmosphere furnace. This process prepares the element to be bent into a variety of configurations. Standard fin density is five fins per inch, while eight fins per inch can be furnished when specified for lower sheath temperatures.

Features of finned air tubular heater
1. Versatile — Ideal for both comfort and industrial process air applications. Stainless Steel (FTSS) sheath and fin material are available.
2. Fins greatly increase surface area and permit faster heat transfer to the air, resulting in lower element surface temperatures.
3. Construction — Element is constructed like the standard tubular element with the addition of continuous spiral fins (4 - 5 per inch) permanently furnace brazed to the sheath.
4. High Watt Density permits use of fewer elements or higher concentration of installed kW for a given area.
5. Easy Installation — Bending configurations can be designed to fit either round or rectangular ducts. Tight element bends are repressed in hydraulic presses after bending to assure recompaction of refractory material to eliminate hot spots and electrical insulation voids.
6. Power Connections should be made with alloy wire.
7. Over temperature Protection — A high limit temperature cut out is recommended.
8. Bending — Finned tubular elements may be field or factory bent according to the following parameters: I Shape, U Shape and W Shape
9. Special Terminal Construction — Many types of terminals are available to suit different applications.
