Finned tubular for air duct heater

Short Description:

Finned tubular heaters are superior to tubular heaters since fins greatly increase surface area, permit faster heat transfer to air and permits putting more power in tighter spaces—like forced air ducts, dryers, ovens and load bank resistors resulting in lower element surface temperature. They are made of up of tubular heating elements and are equipped with electro galvanized steel fins. Mechanically bonded continuous fins assure excellent heat transfer and helps prevent fin vibration at high air velocities. As the surface area is increased and heat transfer is improved due to fins, it results in lower sheath temperature and maximizing of element life.

All stainless steel;

Spiral fin:

for φ8mm pipe: stainless steel finning - ＞φ18，φ24 iron fining - φ23

for φ10mm pipe: stainless steel finning - ＞φ20，φ26, φ30 iron fining - φ25, φ 30

Other dimensions, wattages and voltages available on request

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)
