EDGE WOUND STRIP HEATER
The Edge Wound Strip Heater, frequently referred to in the industry as a Bayonet Heater, is engineered for one specific purpose: optimizing radiation efficiency. Unlike standard flat elements, this heater features a resistive strip that is coiled on its edge rather than its face.
This unique construction creates a “bayonet” profile that dramatically increases the surface area exposed to the air or furnace atmosphere. The result? A robust heating element capable of delivering intense, uniform heat up to 1000°C without the hot spots that often cause premature failure in conventional heaters. At Walta Heater, we custom-engineer these units to fit precise voltage and wattage requirements, ensuring they act as the reliable heart of your industrial oven or furnace.
Advantages of Edge Wound Strip Heater
- Superior Heat Dissipation: Because the strip is wound on its edge, it allows for better air circulation around the element. Consequently, the heater runs cooler internally while delivering more heat to the process, extending its operational life.
- Structural Rigidity: The edge-wound geometry is mechanically stronger than flat-wound ribbons. As a result, the element resists sagging and deformation even when mounted horizontally at high temperatures.
- Rapid Thermal Response: The low thermal mass of the strip allows the heater to heat up and cool down quickly. Therefore, it provides precise temperature control for sensitive processes like tempering and annealing.
- Versatile Application: Whether used in stagnant air or forced convection systems, the sturdy design handles vibration and thermal shock better than ceramic-encased alternatives.
