Product Specification
Forced convection chamber furnace NA 15/65 I as 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. 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)
