DescriptionElectric Finned Tubular Air Heater 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 hear transfer to air, resulting in lower surface element temperatures.finned tubular heaters provide rapid heat transfer for natural convection or forced air space heating in industrial process air heating systems. Finned tubular heaters start out as a standard tubular heater with the fins being attachedon a custom built finning machine.TUBE MATERIALFIN MATERIALTUBE DIA.(MM)FIN HEIGHT(MM)FIN THICKNESS(MM)FIN PITCH(MM)SS304/316/321/IncoloySS304/316/321/IncoloyΦ6.7 3-5 0.3-0.43-5SS304/316/321/IncoloyS.Steel / mild Steel Φ83-50.3-0.43-5SS304/316/321/IncoloyS.Steel / mild Steel Φ93-5 0.3-0.43-5SS304/316/321/IncoloyS.Steel / mild Steel Φ105-70.3-0.43-7SS304/316/321/IncoloyS.Steel / mild Steel Φ125-70.3-0.43-7SS304/316/321/IncoloyS.Steel / mild Steel Φ145-100.3-0.43-7SS304/316/321/IncoloyS.Steel / mild Steel Φ16 5-100.3-0.45-7SS304/316/321/IncoloyS.Steel / mild Steel Φ20 5-100.3-0.47-10 Advantages1.Good sealing ,no pollution 2.Compacted with insulating MgO,heating faster3.Virtually a limitless array of custom bend formation options, to include adapting heater element around space parameters - to maintain maximized efficient heating.Applications for Electric Tubular Heater* Forced air heating for dryers, ovens, ducts* Still air heating for ovens, comfort heating* Incubators* Ink drying* Load bank resistorsMain Features1.
