Float Glass Heating Elements | High-Efficiency Silicon Carbide
Heating Elements
The World's Second Most Electrically Efficient Float Glass Heating
Elements
For facilities where the most energy-efficient 28mm cold end
element cannot be installed due to terminal block constraints,
Starbar offers the next best solution: our 19mm cold end float
element—delivering the second-highest electrical efficiency globally.
Why Cold End Design Determines Efficiency
Energy efficiency in heating elements begins at the cold ends.
While our 19mm diameter matches industry standards, our design
delivers significantly lower electrical resistance. Here's why:
- Solid Beta Silicon Carbide Construction: Unlike tubular or high-resistance alternatives, our 19mm cold end
is made from solid low-resistance Beta SiC, offering greater
electron flow surface area.
- Negative Temperature-Resistance Relationship: Resistance decreases as temperature rises—optimizing power
consumption during operation.
- Minimized Roof Module Heat Loss: By reducing resistance in cold ends, less energy is wasted
heating non-critical zones.
By comparison, competing one-piece 19mm cold ends made of Alpha SiC
with silicon impregnation exhibit higher initial resistance, which increases with temperature—resulting in higher operating
costs and energy waste.
Starbar's 28mm and 19mm cold ends are engineered to approach the
ideal: near-zero resistance cold terminals for maximum usable power delivery.
Long-Life Hot Zones: Engineered for Durability
Our Type W three-phase hot zones are manufactured to last, using:
- Self-Bonded Recrystallized Alpha SiC
- High Density of 2.50 g/cm³
- Low Porosity & High Structural Integrity
These features ensure slow aging and outstanding thermal stability, with an average service life of 15 years—reducing replacement frequency and total cost of ownership.
Superior Welding Technology for Maximum Reliability
We go beyond standard welding to ensure joint integrity and
electrical performance:
- Serrated Cold End Butts: Prior to welding, we texture the contact surface for stronger
bonds and improved electrical contact.
- Two-Piece Bridge Design: Allows precise electrical connection and superior weld quality
across all three hot section legs.
