Electric Air Duct Heater
Firebar Elements
When conventional round tubular heating elements reach their limits, Firebar® flat tubular heating elements offer a smarter, more efficient solution. Manufactured and supplied by Backer Cynebar Ohmic, these innovative flat profile heaters deliver higher heat transfer efficiency, lower sheath temperatures, reduced fouling, and longer service life in demanding industrial heating applications. Designed for immersion heating, tank heating, process fluids, oils, water, chemicals, and air heating applications, Firebar® elements provide significantly greater surface area than traditional round tubular heaters while maintaining a compact footprint.
FIREBAR ELEMENTS
Why Choose Firebar® Flat Tubular Elements?
The unique flat profile design improves heat transfer by increasing the surface area available for heat dissipation while reducing the distance heat must travel through the insulation layer. This results in:
- Faster heat-up times
- Lower sheath temperatures
- Reduced fluid degradation
- Less coking and scaling
- Improved energy efficiency
- Longer heater life
- More compact equipment designs
Compared with a conventional round tubular element of equivalent watt density, Firebar® elements can often achieve lower operating sheath temperatures while providing the same heating output.

Key Benefits
Increased Surface Area
The flat tubular profile provides approximately 70% greater surface area than a comparable 10.9 mm diameter round tubular element of the same length. This allows:
- Lower watt density
- Higher wattage in the same space
- Improved heat transfer efficiency
- Extended operating life
Faster Heating Performance
The streamlined shape encourages improved fluid flow around the element surface. Reduced turbulence and heat trapping enable more effective heat transfer into the medium being heated.
Reduced Scaling and Coking
The flat profile minimises surface areas where solids can accumulate. Lower sheath temperatures help reduce:
- Carbon build-up
- Fluid degradation
- Lime scale accumulation
- Maintenance requirements
Compact Design
For equivalent wattage and watt density, Firebar® elements can be up to 41% shorter than comparable round tubular heaters. This enables higher power density in space-constrained equipment.
Self-Supporting Construction
The rigid flat construction resists deformation caused by fluid turbulence and vibration, often eliminating the need for additional support brackets.
