Technical data

Furnace housing

Furnace housing, housing of separate switch box and swivelling door (to side, in standard version) consist of a lightweight sheet steel construction. The painting with structural lacquer serves as protection against corrosion. The chosen colours blue/white give a nice appearance to the entire furnace. 

Insulation

The rear ventilated brick lining of the furnace consists of high quality lightweight refractory bricks in combination with modern fiber insulation materials which assure a high thermal capacity at low energy consumption. 

Heating

Heating is effected by free radiating Kanthal-A1 respectively APM heating spirals in the rims of the brick lining. The bottom heating is covered with SiC boards. When door is opened, heating is switched off from mains with a safety switch. 

Switch and control unit

The switch and control unit is located in a separate switch box which is connected to the furnace via flexible lines. The furnace is supplied with the following controller:

  • Temperature controller G400
  • 2 or 3 setpoint controller with PID behaviour
  • Logic output
  • One heating ramp – freely programmable velocity / ramp function
  • Display of actual value (desired value displayed after pressing the button)
  • Self-optimization prevents overshooting
  • Separation of control and configuration level (prevents undesired changes)
  • Alarm signal in case of thermocouple fracture
  • Timer with turn-on & turn-off delay (dwell time)
  • Temperature control for protection against overheating
