Descrizione

Our tubular heaters have a diameter of 6.5mm and 8.5mm and consist of high-alloyed chromium-nickel steel. The current-carrying, spiral-wound heating conductor is made of high-temperature-resistant chromium-nickel resistance wire. This heating conductor is centrically embedded and insulated inside the jacket pipe. Fine-grained magnesium oxide characterised by its particularly good heat conductivity and excellent insulation values even in case of high temperatures is used for insulation. The heat element ends are unheated and sealed as well as locked with a ceramic end bead according to their intended purpose. The surface load of the tubular heaters in W/cm² depends on the intended purpose. Therefore, the performance and dimensions of all tubular heaters have to be designed according to their intended purpose.''
