FIREBAR Clamp-On

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:

Features	Benefits
Greater surface area per linear inch compared to round tubular heaters	Reduces watt density or packs more kilowatts in smaller bundles
Compacted MgO insulation	Maximizes thermal conductivity and dielectric stength
Nickel-chromium resistance wires	Precision wound
0.040 in. (1 mm) thick MgO walls	Transfers heat more efficiently away from the resistance wire to the sheath and media Conducts heat out of the element faster
Three resistance coil design (double ended only)	Configurable to either one- or three-phase power readily adapts to a variety of electrical sources and wattage outputs
Slotted end (single ended only)	Provides installation ease in clamp-on applications
Lavacone seals	Provides protection against humid storage conditions moisture retardant to 221°F (105°C)
