| Lead wire: | 300mm / 400mm / 500mm / 900mm (Customized is accept) |
| Electrode | Welding leads on the electrode |
| Advantages | > Ready to fit solution: High temperature heating element in temperature-resistant ceramic socket |
| > Air can flow through and around inside and outside of heater | |
| > Element temperature: over 1000 °C in permanent and alternating operation, for a short time up to 1200 °C | |
| > Lifetime up to 100,000 heating cycles, depending on operating conditions | |
| > Oxidation and corrosion-resistant | |
| > Ignition through air heating: Due to extremely high heater temperature and ideal geometric conditions, air is heated in a very short time to very high temperatures | |
| - the ideal ignition blower! | |
| > Igniting wood chips, firewood, coal bricks or other biomass (corn, etc.) is possible. |
