How To Choose A Tube Furnace


  1. Know your application

  • Single Zone vs Multi-Zone: Multi-zone furnaces have multiple independently-controlled, constant-temperature zones, which allows controlled temperature gradient or a longer heating zone
  • Horizontal (standard) vs Vertical: Vertical tube furnace provides smaller footprint and can be used for fast heating / quenching process
  • RTP (Rapid Thermal Processing): Slideable sample holder or furnace for maximum heating / cooling rate
  • Rotary Tube Furnace: Tube is rotated during heating for better powder processing / coating uniformity
  • Gas Processing Capability: Special models for Hydrogen gas processing and high-temperature corrosion research are available
  • Multi-Function: Tube furnace based complete systems, such as CVD, PECVD, HPCVD, ALD, Graphene & 2D material growth system, are available

2. Certifications for tube furnace

  • All NBD’s furnaces are assembled and quality controlled in China and CE certified

3. Choose working temperature

  • Please note there are maximum temperature (can be maintained < 1 hr) and continuous working temperature (safe, continuous use temperature)
  • The maximum working temperature depends on the heating element used, and can be divided into three categories:

    a. Working temp: ≤1150 °C       Max temp:1200℃ alloy heating element        K type thermocouple

    b. Working temp: ≤ 1450 °C       Max temp:1500℃ SiC heating element         S type thermocouple

    c. Working temp: ≤ 1650 °C       Max temp:1700℃ MoSi2 heatin element      B type thermocouple

  • Select the processing tube corresponding to the furnace max temperature:
