Description

Finned Tubular Heater
Finned Tubular Heaters are designed for use in natural and forced convection space heating, 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 environments. 
Some applications require stainless steel materials for corrosion resistance. 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 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 steel.

An electrically insulating layer such as a ceramic is applied on the outer surface except for one exposed portion. Electrically resistive heaters are then applied to the insulated regions and are electrically connected at one end to the underlying electrical conducting region.
 
The electrical conductor is connected to the negative terminal of a power source. The other end of all the heaters are adapted to be connected to the positive terminal of the source. Accordingly, an electrically resistive heating circuit is formed wherein the tube serves as a common for all of the heating elements.
 
The tubular heater can comprise an exposed end hub with a plurality of blades extending therefrom. Each blade can have an individual heater deposited thereon. Alternatively, every other blade can have a heater deposited thereon. The blades having no heater function as barriers to minimize outward escape of generated vapors. These barrier blades also function as heat sinks for the heaters on adjacent blades.
 
Applications:
Commercial food industry, clamp-on heating, static and forced air applications, pre-weld heat treating, salt baths, and molten metal applications. Used to convert from gas or oil fired burners. Used for drying products or parts. For industrial water boilers, hot water storage tanks, and wash tanks. Melting oils, fats, lards, tar and asbestos undercoatings. Sterilizing equipment. Use in heating solutions where drainage is impractical. Rinse tanks and degreasers. Replacement element for reflector style radiant housings. Circulation heater used for heating of large diesel engines, such as standby generators for fast warm ups.
