Edge Wound Heater

Tempsens offers specially designed and developed edge wound heater which is also known as bayonet heater. Edge wound elements are used in applications where utmost power is required in limited space. These elements replace rod elements in furnaces requiring more power and are used to convert gas-fired furnaces to electric heating. Different furnaces such as roller hearth, pit, batch, low-temperature aluminium tempering furnaces and high-temperature exothermic gas generators use these heating elements to meet their heating requirement. A nickel-chromium alloy (80/20 or 70/20) forms the basis of these heaters. It delivers maximum radiation of surface area of the element and delivers high wattage in a limited area.
