HTTF-800-III-R-AC Anti-Corrosive Rotary Tube Furnace is a three zones vacuum 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.
