Edge Wound Heater

Edge Wound Heaters, also known as bayonet heaters, represent the pinnacle of high-performance industrial heating technology specifically engineered for demanding furnace applications requiring superior heat transfer efficiency and compact design solutions. These advanced ribbon heating elements feature a sophisticated construction methodology where premium NiCr (Nickel-Chromium) or FeCrAl (Iron-Chromium-Aluminum) alloy strips are precision wound on edge and strategically mounted on high-grade ceramic supports to deliver exceptional surface watt density and uniform heat distribution throughout the heating zone.

Manufactured using cutting-edge metallurgical techniques and superior alloy materials including NiCr 80/20, NiCr 70/30, and advanced FeCrAl compositions, these high-temperature bayonet heaters are capable of operating continuously at temperatures up to 1050°C while maintaining structural integrity and consistent thermal performance. The unique edge-wound ribbon design maximizes surface area exposure, enabling rapid heat-up capabilities and superior heat transfer coefficients compared to conventional rod or strip heating elements.

These industrial-grade edge wound heating elements are available in extensive power ratings from 1 kW to 65 kW per element, making them ideally suited for diverse thermal processing applications including roller-hearth furnaces, pit furnaces, batch furnaces, aluminum tempering systems, exothermic gas generators, and specialized heat treatment equipment. The precision-engineered ceramic support system ensures optimal mechanical strength while providing electrical isolation and thermal stability under extreme operational conditions.

Key technological advantages of these furnace heating elements include their ability to deliver high watt density outputs ranging from 5 to 15 W/cm², facilitating compact furnace designs without compromising heating performance. The advanced alloy compositions provide exceptional resistance to high-temperature oxidation, thermal cycling stress, and corrosive furnace atmospheres, ensuring extended operational life and reduced maintenance requirements compared to traditional heating systems.

As an energy-efficient industrial heating solution, Edge Wound Heaters offer superior thermal efficiency through their optimized heat transfer design, reducing overall energy consumption and operational costs. The customizable mounting configurations, including both horizontal and vertical installation options, provide exceptional design flexibility for various furnace layouts and space constraints. Their modular construction enables simplified installation, maintenance, and replacement procedures, making them the preferred choice for industries seeking reliable, high-performance heating technologies with minimal downtime and maximum operational efficiency.
