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) ../12 series when higher application temperatures are needed.

Standard Equipment

  • Tmax 1400 °C
  • Heating from two sides
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
  • Adjustable air inlet integrated in door
  • Exhaust air outlet in rear wall of furnace
  • Controller with touch operation B510 (5 programs with each 4 segments)
  • Solid state relays provide for lownoise operation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Дополнительное оборудование

Additional Equipment

  • Chimney, chimney with fan or catalytic converter
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Protective gas connection to purge with non-flammable process gases (not available in combination with chimney, chimney with fan or catalytic converter), not gas tight
  • Manual or automatic gas supply system
  • Process control and documentation via VCD software package for monitoring, documentation and control
