Uszczelnione piece komorowe z cyrkulacją powietrza

Obie wersje różnią się tym, że wariant I ma tylko uszczelnioną obudowę zewnętrzną, natomiast w przypadku wariantu SI skrzynka wewnętrzna jest zespawana, co prowadzi do mniejszej zawartości tlenu szczątkowego.

Sealed forced convection chamber furnaces are suitable if a heat treatment process up to 850 °C requires a protective gas atmosphere that does not have to be completely oxygen free. The difference between the two variants is that the I-model only has a sealed outer housing while the SI-model has a welded inner box, which further reduces the residual oxygen concentration.

NA(T)-I design 

Like forced convection chamber furnaces < 675 l with the following changes

  • Tmax 650 °C and 850 °C
  • Silicone door seal
  • Furnace housing sealed with silicone
  • Protective gas connection in the back wall
  • Residual oxygen concentration < 1 % depending on the volume and type of protective gas
  • For non-flammable protective and reaction gases such as argon, nitrogen, and forming gas (national regulations must be considered)
  • Defined application within the constraints of the operating instructions

NA-SI design

Additional features

  • Tmax 650 °C
  • Welded inner housing
  • 2-sided heating and air circulation
  • Door sealed with seal gas
  • Sealed connection to circulation motor
  • Gas inlet via circulator shaft
  • Residual oxygen concentration to 0.1 % depending on the volume and type of protective gas
  • For non-flammable protective and reaction gases such as argon, nitrogen, and forming gas (national regulations must be considered)
  • Defined application within the constraints of the operating instructions
