Sealed Forced Convection Chamber Furnaces NA-I and NA-SI

Forced convection chamber furnace NA 120/65 I 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 (page 34) with the following changes

  • Tmax 450 °C and 650 °C
  • 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
  • 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)

Chamber Furnaces for Processes with High Vaporization Rates of Organic Matter or for Thermal Cleaning by Ashing Electrically Heated or Gas-Fired

Chamber furnace N 650/14 BO with ignition burner

The chamber furnaces of the model series N(B) .. BO are used for processes with large amounts of organic matters or high vaporization rates. These models can be used for products which are insensitive against temporarily uncontrolled temperature increases. Processes in which the product or contaminations on the product are ashed by ignition can be also carried out safely in this type of chamber furnace. Examples include residual wax removal of pouring clustersfollowed by sintering, or thermal cleaning of oxide catalytic honey combs from soot or fuel residues. The electrically heated N...BO furnaces can be used for processes with exact temperature control and uniformity. For safety reasons, they are equipped with an integrated gas torch for igniting the flammable components in the gas mixture. The accumulation of flammable components is avoided and their safe combustion is ensured.

The gas-fired NB…BO furnaces are designed for processes which require a heat-up time to temperatures > 500 °C

The burning of unwanted organic ingrediants can take place at temperatures > 500 °C. Following this, a subsequent process can take place up to max. 1400 °C (electrically) or up to 1000 °C (gas-fired).

For safety, the furnace door locks after the program was started and cannot be opened again until the temperature has dropped below a defined value. In case of burner malfunction or gas shortage the process is aborted.

Chamber furnaces N 100 BO - N 650/14 BO, electrically heated and gas-fired ignition flame

  • Tmax 1000 °C or 1400 °C
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Standard sizes up to 650 liters furnace chamber, additional sizes on request
  • Exhaust hood
  • Fully automatic temperature control
  • Optional thermal afterburning
  • Ignition flame using natural gas or liquid gas (LPG)
  • Defined application within the constraints of the operating instructions

Chamber furnaces models NB 300 BO and NB 650 BO, gas-fired

  • Tmax 1000 °C
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Standard sizes up to 650 liters furnace chamber, additional sizes on request
  • Integrated thermal afterburning
  • Gas burners operating with natural gas or liquid gas (LPG)
