Muffle Furnaces up to 1400°C

These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times and a maximum temperature of 1400 °C. These muffle furnaces are a good alternative to the familiar L(T) ../11 series when higher application temperatures are needed.

  • Tmax 1400 °C
  • Heating from two sides
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Dual shell housing for low external temperatures and high stability
  • Adjustable air inlet integrated in door
  • Exhaust air outlet in rear wall of furnace
  • Solid state relays provide for low-noise operation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

  • Chimney, chimney with fan or catalytic converter
  • 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
  • Protective gas connection to purge with non-flammable protective or reaction gases (not available in combination with chimney, chimney with fan or catalytic converter)
  • Manual or automatic gas supply system
  • Process control and documentation via VCD software package for monitoring, documentation and control
