Carbolite AZ-8-Zone Tube Furnaces AZ-13-80-810 1350℃

The AZ is an eight zone tube furnace for controlled temperature profiles.These zones can be used to generate temperature profiles along the heated length of the furnace.

With eight zones,thick insulation,and highly symmetrical winding of the heating elements throughout the entire AZ furnace,a uniformity of better than ± 5℃ 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.

inner insulation (hot face)

The rectangular housing is constructed with slots for convection cooling of the outer housing. With insulation made from low thermal mass ceramic fibre material,the heat conduction is reduced to a minimum.

Inside the tube furnace,the heating element is constructed of vacuum formed fibres containing free radiating heating elements that are attached to the insulation by a ceramic holding ridge.

When compared to conventional heating methods,the 5 mm thick heating wires are combined with a low voltage,heavy-weight transformer power supply that provides an extraordinary long lifetime of the heating elements and temperature stability. The control thermocouple is a high grade type S thermocouple. Additionally,each tube furnace model is available with up to 8 heating zones for the most precise temperature control and uniformity.
