Kanthal heating brand is lightweight construction and has become the norm of many industrial furnace applications with the use of ceramic fibers (KF) up to furnace temperatures of 2820°F.
The low thermal mass and thermal conductivity of the ceramic fiber furnace linings mean that you can build industrial furnaces which, depending on the type and mode of operation, contribute significantly to energy saving, higher output and better availability.
In the electrically heated furnace, however, it is very expensive and time consuming to combine ceramic fibers, such as blankets or folding blocks, with electric heating elements. This has led to the Kanthal product, introduced in 1978, as Fibrothal.
Today the Fibrothal trademark covers a family of products consisting of vacuum-formed ceramic fiber components, with or without electric heating elements.
