1. Température de fonctionnement: 1100℃ (1200℃ pendant une courte période).
2. L’efficacité énergétique maximale est obtenue en entourant la chambre avec une isolation en céramique à fibre d’alumine thermo-efficace.
3. Structure à double couche résistante avec ventilateur. Plus basse température dans le cas extérieur.
4. Le contrôle automatique PID via l’angle de phase de limitation de courant a déclenché la résistance, par exemple SCR (redresseur commandé par silicium).
5. Contrôle de puissance avec 51 segments programmables.
