These compact tube furnaces with SiC rod heating and integrated switchgear with controller can be used universally for many processes. They represent an inexpensive variant in the high-temperature range. The standard mounting options for accessories make them flexible in use for a wide range of applications. The SiC heating elements arranged parallel to the working tube provide for an excellent temperature uniformity.

Standard Equipment

  • Tmax 1600 °C
  • Working temperature 1500 °C, increased wear and tear must be expected in case of working at higher temperatures
  • 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)
  • Active cooling of housing for low surface temperatures
  • Ceramic working tube C 799 including two fiber plugs for operation under air
  • Type S thermocouple
  • Solid state relays provide for lownoise operation
  • SiC heating elemens, easy to replace
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Controller P580 (50 programs with each 40 segments)

 

Additional equipment

Additional Equipment

  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Charge control with temperature measurement in the working tube
  • Gas supply systems 1, 2 or 4
  • Process control and documentation via VCD software package for monitoring, documentation and control
