Furnace Structure
|
• Double layer steel case with air cooling to ensure furnace surface temperature < 60 °C- • Energy saving high purity fibrous alumina insulation.
• Heating Element : 1300ºC grade Fe-Cr-Al Alloy doped by Mo - • 41 "length x 5.5"dia heating chamber with 7 built in thermal couples to accept processing tube from
1" - 5" dia.x2000 mm length - • Splittable cover is lift and closed by a pair of heavy duty compressed air spring to make tube replacement at easy.

|
• Quartz Tube: 130 OD x122 ID x2000 L mm (5"x 79") (The tube is consumable , click picture below to
order spare )- • Two fibrous alumina thermal blocks are included , which must be placed on two end of inside tube
( click pic below right )
 
|
Vacuum Flange
|
• One pair stainless steel vacuum flange is included with quick assembling flange
( a outside clamp for quick installation)- º Left flange installed with needle valve with 1/4" pipe port for gas inlet ( Pic below left )
- º Righ flange built in K25 port and Anti-Corrosive digital vacuum gauge to connect a vacuum pump
  
|
Heating Zone
| |
|
• One touch screen digital temperature controller built in a separated unit, which can control seven heating zones
independently- • Each channel is PID automatic controlled and saves 10 programs and each program has max. 30 segments
- • Built in overheating & broken thermocouple protection.
- • +/- 1 ºC temperature accuracy.
- • Seven K type thermocouples (one for each zone).
- • RS485 Communications Port built in. and software included,
- • The furnace may be operated by PC ( please order PC separately ).

Warning
Click here to learn the installation of a gas regulator
|
• The tube furnaces with quartz/mullite tube are designed for using under vacuum and low pressure < 0.2 bar /
3 psi / 0.02 MPa- • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to
below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. - • * Vacuum pressures may only be safely used up to 1000°C
- • The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
