Furnace Structure
 | Double-layer steel casing with air cooling to keep furnace surface temperature lower than 60°C. High purity fibrous alumina insulation for Max. Energy-saving. The special refractory coating on the inner to increase furnace life. - Two pairs of fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
- Split cover with Interlock protection, cut the power if the door opens during furnace heating process.
|
| Input voltage | 208 - 240VAC SINGLE PHASE, 50/60Hz |
| Power | 6.0 KW （40A Breaker Required） |
Heating temperature  | - Max. heating temperature: 1500°C (< 1hr )
- Continuously heating temperature: 1400°C
- Heating rate: 10°C /min Max. And cooling rate < 10 °C /min Max. for mullite tube
- Note: if using alumina tube: Heating rate: 10°C /min Max. and cooling rate < 5 °C /min Max.
- The S-Type thermal couple included
- 16 pcs SiC rod as heating elements (1500 grade ) Pls click pic left to order spare or replacement
- Notice：Customer will install SiC rod on-site by themselves as instruction manual due to they are easy to damage during shipping.
- Please notice, For the SIC heating element, it is a consumable part, and not covered by warranty, and usually, its service life is one year.

| Vacuum Sealing |      |
| Vacuum level | 10^-2 torr by a mechanical vacuum pump.
10^-5 torr by Turbomolecular pump.
Leak rate < 5 mtorr / min. |
| Pressure Measurement / Monitoring | - Standard mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa.
- OPTIONAL: A gas-type independent (above 10 mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces the risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency.

| Operation Instructions |  |
Warning  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.
- Attention: A pressure regulator must be installed on your input gas tank ( click the picture below to review ) and have the gas output pressure set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition. Gas build-up with pressure levels exceeding over 3 PSI may cause irreversible damage to the furnace chamber.
- 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.
- The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
- Vacuum pressures may only be safely used up to 1300°C
- NOTE The mullite tube shall be considered as a consumable part. We strongly recommend users keep spare tubes to ensure the continuity of operation. The tube is not covered by the Warranty. Use the link to order more.
|
| Attention Notes | - Performance degradation (i.e. furnace can not reach the maximum temperature of 1500°C, or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen. Please order the replacements from the standard package list below.
