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 recirculation 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 heating. 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 recirculation
• Tmax 900  °C or 1280  °C for furnaces with radiant heating
• Electrically heated or gas-fired
• Heating from both long sides for furnaces with air recirculation
• 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 manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

Additional equipment

• Automatic exhaust air flaps for faster cooling
• Controlled fan cooling with electrically 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 with Controltherm MV software package
