Finned Tubular Heaters

Finned Tubular Heaters are normally used in forced circulation heating of low temperature air, other atmospheres and gases. Typical applications include forced convection heating of air, process atmospheres, and oven atmospheres in duct environment. Usually finned material is placed above the tubular heaters which basically are used for the heating purpose. The most efficient finned heaters are made with steel sheath and steel fins. Steel is normally used for air heating, stainless steel for atmospheres, which are humid or corrosive, and monel for salt-laden humid atmospheres. Keep in mind that stainless heaters with stainless fins are very inefficient since the heat transfer rate of stainless is less than one quarter that for steels.
