Fiber Heating Modules

Lightweight construction has become the norm in many industrial furnaces, with the use of ceramic fibers (KF) up to furnace temperatures of 1800ºC. 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 blankets or folding blocks, with electric heating elements.

These modules can be used for almost all furnaces layouts. In addition to panels for furnaces with flat walls we manufacture many different module designs for cylindrical surfaces, such as for example tubes up to 500 mm diameter and half-cylinders up to 650 mm diameter. For larger inside diameters shell modules (1/3, 1/4, 1/6, shells, etc.) are used. The design corresponds in principle to that of the standard panels or half-cylinders. The maximum element temperature is also 1150ºC.

The heating surface is the surface which accommodates the heating element. The standard module dimensions are based on the heated surface dimensions plus the minimum required unheated edge area. Panels can be manufactured to a maximum width or length of 1050 mm.
