  • Patent number: 6414281
    Abstract: A multicell heater is shown with typically round outer tubing, containing a plurality of resistive heating elements having a common inner sheath. The inner sheath has a preferably non-circular cross-section and is given a hairpin bend to form a “U” shape. The resulting configuration, which is much less expensive than conventional multicell heaters, provides efficient heating at the toe end—a usually unheated (“cold”) zone in conventional multicell heaters.
