Designed as tabletop models, these compact high-temperature furnaces have a variety of advantages. The first-class workmanship using high-quality materials, combined with ease of operation, make these furnaces all-rounders in research and the laboratory. These high-temperature furnaces are also perfectly suited for the sintering of technical ceramics, such as zirconium oxide dental bridges.

Standard Equipment

  • Tmax 1600 °C, 1750 °C, or 1800 °C
  • Recommended working temperature 1750 °C (for models LHT ../18), increased wear and tear must be expected in case of working at higher temperatures
  • High-quality heating elements made of molybdenum disilicide offer very good protection against chemical interaction between charge and heating elements
  • 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 opening
  • Exhaust air opening in the roof
  • Thermocouple type B or type S (LHT ../17 D)
  • Controller with touch operation P580 (50 programs with each 40 segments)
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

 

Additional equipment

Additional Equipment

  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Port for thermocouple in the furnace roof
  • Protective gas connection to purge with non-flammable process, not gas tight
    Manual or automatic gas supply system
  • Stackable saggars for loading in up to two or three levels, depending on model,
  • Process control and documentation via VCD software package for monitoring, documentation and control
