Carbolite AZ Eight Zone Tube Furnace Carbolite AZ Eight Zone Tube Furnace

Carbolite AZ Eight Zone Tube Furnace

The Carbolite AZ Eight Zone Tube Furnace is for controlled temperature profiles. These zones can be used to generate temperature profiles along the heated length of the furnace.

Key Features

  • Similar construction to FHA / FHC tube furnaces
  • Eight-zone control for variable heating profiles
  • Gradients, linear increase/decrease etc. of temperature along the heated length

Please note - Product designs and specifications are subject to change without notice. The user is responsible for determining the suitability of this product.

With eight zones, thick insulation, and highly symmetrical winding of the heating elements throughout the entire AZ furnace, a uniformity of better than ± 5 °C is achieved. A key advantage of the eight individually controlled zones is the extension of the uniform length inside the furnace. Additionally, the temperature profile can be precisely controlled for linear increases, peaks, or other user defined profiles.

One process well suited for the AZ tube furnace is chemical vapour deposition as a temperature gradient can be established in the furnace for evaporation of precursor material at the high temperature end zone and sublimation of the vapour onto the substrate at the cooler temperature end zone. All zones are individually controlled and monitored with thermocouples.
