Advantages

Element replacement is fast and easy. Element changes can be made while the furnace is hot, following all plant safety procedures. All electrical and replacement connections can be made outside the furnace. No field welds are necessary; simple nut and bolt connections allow for quick replacements. In some cases, replacement can be completed in as little as 30 minutes depending on the size of the element complexity and accessibility.
Each element is custom designed for peak energy efficiency. Furnace temperature, voltage, desired wattage and material selection are all used in the design process.
Inspection of the elements can be performed outside the furnace.
When necessary, as with a reducing atmosphere, bayonets can be operated in sealed alloy tubes.
