KERASTRIP / CERAMIC INSULATED FLAT HEATERS

TECHNICAL DATA
   1. RESISTIVE WINDING spiral made of Nickel/Chrome 80/20 DIN 17470, material n° 4869, characterised by large section and consequent low power density, executed with automatic toolswhich insure long duration. The spiral is uniformly distributed within the circuit which is realised by a mosaic of ceramic blocks. This solution guarantees a perfect distribution of the heat
   2. ELECTRICAL INSULATION made of high purity ceramic KER 221 DIN 40685 which presents a high resistance to thermal shocks and a high dielectrical rigidity. The peculiar internal structureof the ceramic insures a rapid and uniform transmission of the heat. Thanks to the high temperatures which are reached and to the particular shape of the mosaic, the heat is transmittedboth by conduction and radiation.
   3. THERMAL INSULATION made of high purity continuous mica with a very low presence of binder. The material complies to UL (94 V-O) Specification.
   4. COVER SHEATH made of galvanically treated steel. Thanks to its high thermal conductivity, it insures the best heat transmission thanks to its compressing action exerted onto the heatingsurface. Heaters without external sheath can be produced too.
   5. COUNTER-FLANGES (optional) made of galvanically treated steel, 5 mm thick. They can be installed between mosaic and the cover sheath
   6. CERAMIC TERMINAL BOARD connecting the power supply cables to the internal electrical circuit. A metallic cover protects the ceramic board from shocks and cables tearing.
   7. POWER SUPPLY CABLE (optional) suitable for high temperatures, with internal conductors in nickel-plated copper or in pure nickel (for the most severe applications). Internal insulation madeof fibreglass and Teflon. Externally protected by a metallic braid sheath.OPERATING TEMPERATURE up to 400 °CSPECIFIC POWER normally designed at 4 ÷ 6 W/cm2. In specific applications values as high as 8 W/cm² can be obtained
