Protective Gas Boxes for Models SAL 30/45 - SAL 500/85

For tempering and bright annealing, workpieces are laid in the box, the lid is pressed firmly shut using the sealing locks and flushed with protective gas outside the box for some time and then placed in the furnace. Due to weight reasons we recommend to use a charging aid for charging.

• For non-combustible protective and reactive gases argon, nitrogen and forming gas (observe national regulations)
• Protective gas box with fiber seal and cover with locks, inert gas introduction via a pipe into the bottom of the box
• Protective gas connection via quick coupling with hose connector (inner diameter 9 mm)
• Piping for gas inlet and outlet through the furnace collar
• Heat-resistant alloy: 450 °C - 304 (AISI)/(DIN material no. 1.4301), 650 °C - 321 (AISI)/(DIN material no. 1.4541) or 850 °C - 309 (AISI)/(DIN material no. 1.4828)
• Charging aid lifting eyes
• Charge thermocouple type K for temperature display or charge control
