Floor and lid heating, two-zone control

These fast-firing furnaces are ideal for simulation of typical fast-firing processes up to a maximum firing temperature of 1300 °C. The combination of high performance, low thermal mass and powerful cooling fans provides for cycle times from cold to cold up to 35 minutes with an opening temperature of approx. 300 °C.

Standard Equipment

  • Tmax 1300 °C
  • Ceramic grid tubes as charge support
  • Floor and lid heating, two-zone control
  • Special arrangement of the heating elements for optimum temperature uniformity
  • Rapid switching cycles result in precise temperature control
  • Integrated cooling fans, programmable to speed up charge cooling including housing cooling
  • Programmable lid opening of approximately 60 mm for faster cooling without activating the fan
  • Thermocouple type S for top and bottom zone
  • Castors for easy furnace moving
  • Controller P470 (50 programs with each 40 segments)
