Inert Gas Retort Furnaces

T max. 1100 °C

Protective gas retort furnaces are designed for heat  treatment processes, which can be carried out only  under oxygen-free atmosphere, such as bright annealing, tempering, sintering, soldering. The program  includes chamber and shaft furnaces.

  • Gas-tight retort furnaces in robust design with horizontal retort
  • Retort made of highly heat resistant steel with special gasket and water-cooled flange
  • Multiple-sided heating, therefore uniform temperature distribution in the retort
  • Parallel guided swing door with encapsulated insulation
  • Suitable for various shielding gases such as Nitro- gen, Argon, forming gas 95/5
  • Very low gas consumption

Retort shaft furnaces

  • Individual design, specially adapted to the process and the batch dimensions
  • Shaft furnaces to be loaded from top with vertical, gas-tight retort, crane loading possible
  • Retort made of highly heat resistant steel with special gasket and water-cooled flange
  • All-round heating for very uniform heating of the retort and the batch
  • Cover with vertical movement, special seal with water cooling
  • Suitable for various protective gases such as Nitro- gen, Argon, forming gas 95/5

Options:

  • Retort with gas circulation (T max. 900 °C)
  • Automatic gassing device
  • Vacuum pump for cold evacuating of the retort
  • Process control via batch thermocouple in the retort
  • Cooling system with exhaust air flap control for cooling to reduce the process times
  • O2-measuring instruments for monitoring
