TUBE FURNACE

 The range of GWL horizontal rotating tube furnaces 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 3-zone split tube furnaces have a maximum operating temperature of 1200 °C. All models are available with maximum heated lengths of either 9000 mm or 12000 mm. The angle of inclination can be easily adjusted between horizontal and 15 °.A safety switch automatically prevents heating when the furnace is opened.

  The system is specially made to prevent the danger of closure of the exhaust port, the blockage of the exhaust port and the excessive pressure of the furnace tube. The signal is obtained by the electric contact pressure meter or pressure sensor then the drive control module will close the electromagnetic inlet valve and starts the electromagnetic exhaust valve and the alarm. to ensure the furnace can be used properly and safely.

  Base on gas atmosphere, to prevent the gas leak；Gas leakage alarm detected (indoor) air toxic,   dangerous and other gas content exceeds a certain value, then the drive control module will shut-down the furnace, closes the inlet valve and open the air exhaust, to get the better and safer working environment.

  *It is essential to discuss your application with us to ensure the suitability of the material for use in this equipment.
