DHE offers Tubular heaters are renowned for their adaptability, durability and reliability. They can be virtually factory-fitted to meet a wide range of industrial heating requirements. The fundamental principle of the design is to enclose a resistive wire or coil in a precisely centered metal sheath, surrounded by magnesium oxide, in order to facilitate the efficient transfer of heat from the coil to the heating medium. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials. Tubular heating elements are capable of conveying heat through all three of these modes: Conduction, Convection and Radiation. It’s made by welding or brazing flange with a bunch of hairpin or tubular elements.
