Tubular Heaters

Tubular heating elements can be used for many applications which require a uniform heat source over a distributed area. Tubular heaters are very versatile and can be designed with wide range of diameters, lengths, sheath materials and voltage ratings. The flexibility of these heating elements allows them to be formed into virtually any shape, including precision forming for a tight fit into milled grooves of manifold surfaces. Multiple termination options are available depending on application requirements. These options include threaded stud terminals, flexible lead wire or bulkhead fittings. Customized terminations are available for harsh or high-moisture environments. Tubular heating elements provide an economical, robust, and versatile heat source. The precision fit optimizes heat transfer to the working surface. These tubular elements can be clamped, immersed, cast into metal or spaced away from the work as radiant heaters. They can also be positioned in ducts or vessels for heating air and other gases. The heating element consists of the following typical protective tube materials: - Carbon (mild) steel - Stainless steel and heat-resisting steel - Copper - Incoloy - Bundy - Aluminum The heating element consists of the following typical component parts: - Protective tube - Resistance wire (heating coil) - Magnesium oxide - Terminal pins
