Our top-loading furnaces are perfectly suited for firing, sintering or tempering of long, heavy products. The furnace is usually charged with a factory crane. Due to their high-performance air circulation system, the furnaces provide for excellent temperature uniformity up to a maximum temperature of 850 °C. The top-loading furnaces for the temperature range up to 1280 °C provide for very good temperature uniformity due to their five-side heating. Alternatively, these furnaces can also be provided with gas-fired. Customized dimensions are designed and produced to accomodate the size and weight of the components to be treated.

  • Tmax 260  °C, 450  °C, 600  °C or 850  °C for furnaces with air circulation
  • Tmax 900  °C or 1280  °C for furnaces with radiation heating
  • Electrically heated or gas-fired
  • Heating from both long sides for furnaces with air circulation
  • Heating from all four sides and the floor with SiC plates in the floor as level stacking support for models to 900  °C or 1280  °C
  • Hight-quality insulation, adapted to the specific maximum temperature
  • Electrohydraulic opening system of the lid with two-hand operation
  • Closable air supply vents in the lower area of the furnace chamber
  • Closable exhaust air vents in the lid
  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
  • Defined application within the constraints of the operating instructions

Additional equipment

  • Motor driven exhaust air flaps for faster cooling
  • Controlled fan cooling with motor driven exhaust air flaps
  • Multi-zone control of the heating provides for optimum temperature uniformity
  • Furnace chamber can be devided in length for short workparts, partitions can be controlled separately
  • Designed for Tmax 950  °C, fan blade driven indirectly via a belt to protect the air recirculation motor against over-heating
  • Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
