Application Notes
  • The concept of continuous power feeding and processing can be realized by the use of Magnetic Fluid Sealed Swivel Coupling in line with Volumetric Feeder and Rotary Furnace. Please view the assembling approach diagram and video in below.         
  • For CVD coating, you may choose our multi-channel Gas delivery system and automatic feeding system  as Pic below 
  • The tube furnaces with quartz tube are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 Mpa
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
