Sealed Forced Convection Chamber Furnaces
Forced convection chamber furnace NA 15/65 I as a tabletop model with manual gas supply system.
Sealed forced convection chamber furnaces are suitable if a heat treatment process up to 650 °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.
Description
NA-I design Like forced convection chamber furnaces < 675 l with the following changes
- Tmax 450 °C and 650 °C
- Volume: 30L-675L
- Silicone door seal
- Furnace housing sealed with silicone
- Protective gas connection in the back wall
- Defined application within the constraints of the operating instructions
- 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)
NA-SI design Additional features
- Tmax 650 °C
- Volume: 15L-675L
- Welded inner housing
- 2-sided heating and air circulation
- Door sealed with seal gas
- Sealed connection to circulation motor
- Gas inlet via circulator shaft
- Defined application within the constraints of the operating instructions
- 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)
