FIREBAR® Clamp-On Heaters

Detail FIREBAR clamp-on heating elements provide added heating performance over standard round tubular heating elements—especially for immersion applications in petroleum-based liquids that require high kilowatts.
  The FIREBAR clamp-on heater’s unique flat surface geometry packs more power in shorter elements and assemblies, along with a host of other performance improvements.
  These include: -Minimizing coking and fluid degrading
  – Enhancing the flow of fluid past the element’s surface to carry heat from the sheath
  – Improving heat transfer with a significantly larger boundary layer allowing much more liquid to flow up and across the sheath’s surface
  FIREBAR elements are available in single- and double-ended constructions with one inch or 5⁄8 inch heights. These two configuration variables make it possible to use FIREBAR clamp-on heater elements instead of round tubular elements in virtually all applications.
Features & Benefits 70 percent greater surface area per linear inch compared to a 0.430 in. (11 mm) diameter round tubular heater
