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. Tubular heating elements are available in single-ended and double-ended configurations. Tubular Heaters with a single-ended design have both terminals located at one end of the heater. The other end is sealed. Lead wires that are flexible and are crimped to the terminal pin are equipped with sleeves made of silicone-enriched fiberglass.The double-ended is highly flexible in terms of bending, particularly when bending in the field. Both single-and double-ended structures have a lot of built-in features that help them last a long time.
