KERAPLAST HEATERS / CERAMIC INSULATED BAND 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, executedwith automatic tools which insure long duration. The spiral is uniformly distributed within the circuit which is realised by a mosaic of ceramic blocks.
   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. Thanksto the high temperatures which are reached and to the particular shape of the mosaic, the heat is transmitted both by conduction and radiation.
   3. CERAMIC TERMINAL BOARD connecting the power supply cables to the internal electrical circuit. A special metallic cover protects the ceramic board from shocksand tearings applied to the cables
   4. INTERNAL INSULATION made of fibreglass which improve the heating efficiency and allows a high energy saving
   5. INTERNAL SHEATH made of galvanically treated steel resistant to high temperatures. Its compressing action onto the heating band guarantees an optimum heatexchange efficiency
   6. 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 made of 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
