Application Notes
Click here to learn more about the installation of a gas regulator. |
- The tube furnaces with mullite tubes are designed for use under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI. Vacuum pressures may only be safely used up to 1300°C. The flow rate for gases should be limited to < 200 SCCM for reducing thermal shock to the tube.
- 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 about the installation of a gas regulator.
- Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
|
Warranty |
- One-year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.).
- ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of MTI's One Year Limited Warranty.
|
Compliance
|
- CE Certified
- NRTL or CSA certification is available upon request at extra cost.
