Application Notes
  • Don’t fill any explosive gasses such as Hydrogen or Methane into the Rotating furnace tube without necessary safety controls and supervision.
  • Rotary Tube furnace with ceramic tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
