Finned tubular air heating elements are constructed like basic tubular elements with the addition of continuous spiral fins, 4-5 per inch permanently furnace brazed to the sheath. Fins greatly increase surface area and permit faster heat transfer to air, resulting in lower surface element temperatures.

Application

To heat forced circulation air for heating premises, closed drying circuits in heaters, charge benches, etc.

In general, for any application of forced air heating up to 200C (Maximum temperature with vair = 4m/sec -＞200C)
