Single- and double-ended tubular heaters lend themselves to virtually the entire range of immersion and air heating applications. They have a variety of mounting and termination options that make them ideal for industrial applications. Watlow® tubular heaters are UL® and CSA component recognized up to 240V.
FIREBAR® heating elements provide added heating performance over standard round tubular heating elements—especially for immersion applications in petroleum-based liquids requiring high kilowatts.
The FIREBAR’s unique flat surface geometry packs more power in shorter elements and assemblies, along with a host of other performance improvements. These include:
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 elements instead of round tubular elements in virtually all applications.
FINBAR™ is a special version of the one inch, single-ended FIREBAR. FINBAR is specially modified with fins to further increase surface area for air and gas heating applications.
