Tubular Heaters are the most versatile of all electric heating elements. They are capable of being formed into virtually any configuration. Tubular heating elements perform exceptional heat transfer by conduction, convection and radiation to heat liquids, air, gases, and surfaces.
Straight Tubular Heating Elements
dpstar manufactures standard tubular heating elements for any application. Tubular heating elements are a versatile and economical heat source for a wide variety of industrial and commercial applications. Diameters are ø6.7mm, ø8.2mm, ø9.5mm, ø11.20mm, ø12.0mm, ø12.7mm, ø14.0mm, ø15.8mm, ø16mm and ø19.0mm. Other special sizes are available. Depending on the diameter, lengths can be supplied up to 6m. Standard sheath materials are Incoloy, SS304, SS316, SS309, Copper and Titanium.
Special sheath materials may be available based on diameter and size of the element required. The typical electrical termination is a ceramic insulator with a threaded stud terminal. Flexible leadwire extensions or other mounting options are available for specific applications.
Formed Tubular Heating Elements
Custom heating elements can be provided to any length, formed into any configuration and sheathed in a variety of different materials to suit your application. Likewise, the connection/termination possibilities are limited only by your imagination and the availability of components. Standard terminations include threaded stud, threaded bulk-head, screw lug, quick disconnect spade, ceramic-to-metal hermetic, molded rubber lead, conventional leadwire terminal assembly and more.Dpstar frequently fabricates custom tubular heaters.
Multiple Shaped Tubular Heaters
Multiple shaped tubular heating elements provide an economical, robust, and versatile heat source. These elements are commonly used to fit into milled grooves for hot runner molding systems. The precision fit optimizes heat transfer to the working surface.
