Technical Data - General KF-Modules Chemical Ptopcrtics: KF-moduIes possess high rsistance to chcmicals, including most acids. with the exception of hydrofluoric acid, phosphoric acid and strong bases. Wctting with water and oil has no influence on the propcrcs of the ccramic fibers them- sclves. Aftcr drying or evaporation the thermal and physical propertics arc restored.

Technical Data - Standard Range Heating Modules FIBROTHAL standard heating modules are manu-factured with embedded heating elements, two prin-ciples being followed. Principle I With this method the KANTHAL A-1 heating wires (diameter < 3.5 mm (0.14 in)) are embedded in the ceramic fiber module made of F3 fiber. The maximum element temperature is 1150°C (2100°F). This design is protected by patent. For optimum heat radiation: ͕ The heating wire is made with an oval cross-section Part of the face of the heating wire is bare Օ The inside of the heating wires is largely free of ceramic fibers...

Principle II With this method - used exclusively for heating tubes - a heating wire of KANTHAL A-1 (diameter 5 mm (0.20 in)) is formed to fit into a ceramic fiber module of F17 fiber with ceramic spacers. In this case the heating element lies on the surface of the insulation and is virtually free-radiating. The maximum element temperature is 1300°C (2370°F). A complete range of moulds is available for manufac-turing the standard modules. There are therefore no mould costs in this case. In the new edition of this brochure the previous voltages have been converted to the Eurovoltage (400/230...

Half-Cylinders For horizontal opration the upper half shell should be designed for the pin system (for explanation see Heating Panels). The connections are designed as standard in the form of threaded bolts M8 x 75 mm (2.95 in) long on the back of the module. Other connection designs are available on request, e.g. flexible leads (see Accessories). Fig. 16 FIBROTHAL standard half-cylinders 18

Insulating Parts FIBROTHAL insulating parts are available in the same standard dimensions as the heating modules. The standard range also includes insulating end pieces which fit the outside diameters of the half-cylinders and tubes. If necessary these end pieces can also be supplied drilled to the size of the work tube. The standard thickness is 125 mm (4.92 in) or 50 mm (1.97 in); other dimensions are also available.
