Please email for lead time
Item Number: OTF800XIIIR2
Transported by LTL Freight (Truck)
OTF-800X-III-R2 is a three zones rotary tube furnace designed for use with strong corrosive gases such as HCL and CH4.  The processing tube is made of the double-layer structure of quartz and SS310S and the flange is made of PETF and anti-corrosive rotation fixture, which allows the rotary furnace working at max. 800oC at 3 bar pressure.


Furnace Construction

  • Special design processing tube with a double-layer structure, which allows furnace running HCL corrosive gas at 3 bar pressure up to 800°C  (Please refer the Pic left)
  • The sealing flanges are made of PTFE and the rotating fixture is made of anti-corrosive steel with Teflon coating.
  • Three heating zone rotary furnaces with max. the working temperature of 800ºC @ +/- 1oC accuracy. 
Heating Zone length

  • Three heating zones: each zone length: 150 + 300 + 150 (mm)  total heating zone length 600 mm
  • Constant temperature zone: 300 mm within +/- 2oC if three zones at the same temperature.

Processing tube & Sealing Flange

  • The double-layer structure has inside quartz tube and outside SS310A high-temperature stainless steel.
