Large Multi-temperature Zone Tube Furnace(GWL-DXDWQGA)

  The range of GWL Large Multi-temperature Zone Tube Furnace offers the benefits of simultaneous heating and mixing of the sample, in addition to the use of an inert atmosphere. 

  The furnaces are suitable for continuous material processing. Residence time in the heated zone depends on the degree of inclination and the rotating speed (which can be controlled by the customer) and the length of the working tube, in addition to the flow properties of the material.

  The design of the split furnace, drive system and feeder/ collection assemblies allows the work tube to be easily removed and replaced.  

  The single zone and Multi-heating zone split tube furnaces have a maximum operating temperature of 1300 °C. All models are available with maximum heated lengths of 7500mm.
