Function and equipment

Begasungskasten_NA_1.jpg

Due to the cubic interior of the LH chamber furnaces and the corresponding protective gas boxes, these furnaces are ideally suited for higher batches. Gassing boxes for the LH models have a standard charge thermocuple, which can be used, for example, for charge control. The protective gas inlet and outlet is routed through the furnace collar in the case of a furnace with a swivel door on the left and through the lower furnace collar in the lift-door configuration.

These boxes have a lid for charging from above, protective gas inlet and outlet.

  • Tmax 1100 °C
  • 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
