FIREBAR® Single/Double-Ended Heaters

Detail	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: -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 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.
Features & Benefits	70 percent greater surface area per linear inch compared to a 0.430 in. (11 mm) diameter round tubular heater
	Compacted MgO insulation maximizes thermal conductivity and dielectric strength
	Precision wound nickel-chromium resistance wires
	0.040 in. (1 mm) thick MgO walls transfer heat more efficiently
	Three resistance coil design readily adapts to a variety of electrical sources and wattages outputs
