These compact tube furnaces with integrated control systems can be used universally for many processes. Equipped with a standard working tube of C 530 ceramic and two fiber plugs, these tube furnaces have a very good price/performance ratio.

Standard Equipment

  • Tmax 1200 °C or 1300 °C
  • Single-zoned design
  • 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)
  • Outer tube diameter of 50 mm to 170 mm, heated length from 250 mm to 1000 mm
  • Ceramic working tube C 530 including two fiber plugs for operation under air
  • Thermocouple type N (1200 °C) or type S (1300 °C)
  • Solid state relays provide for lownoise operation
  • Heating elements on support tubes provide for free radiation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Controller B510 (5 programs with each 4 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
  • Three-zoned design (heated length from 500 mm) for optimization of temperature uniformity
  • Gas supply systems 1, 15, 2 or 4
  • Process control and documentation via VCD software package for monitoring, documentation and control
