High-temperature furnaces HFL 16/16 - HFL 160/17 have a sturdy cladding made from refractory insulation. This design offers better protection if the process produces aggressive gases or acids, such as when glass is melted. 

  • Like high-temperature furnaces HT, except:
  • Tmax 1600 °C or 1700 °C
  • Robust refractory brick insulation and special backing insulation
  • Furnace floor made of lightweight refractory bricks accommodates higher charge weights
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

  • Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller.
  • Thermocouple inlet with screw cap
  • Thermocouple for the heating control with calibration certificate
  • Protective gas connection to purge with non-flammable process gases (not completely gas-tight)
  • Automatic gas supply system with solenoid valve and rotameter, controlled by the extra function of the controller
  • Lift door
  • Automatic door lock incl. door contact switch
  • Heating elements protected against mechanical damage
  • Ethernet interface
