In stock
Item Number: GSL-1700X-S60HG
Transported by LTL Freight (Truck)

Personalization

Upgrade to Eurotherm Temp. Controller
GSL-1700X-S60HG tube furnace is designed for processing material under hydrogen gas up to 1700°C safely. The 60 mm OD processing tube is made of pure alumina, and one hydrogen gas detector is included for cutting off hydrogen gas via a built-in solenoid valve immediately upon detection of hydrogen gas leaks. The furnace can be used with all kinds of inert gasses and oxygen gas as well. The precision temperature controller provides up to 30 programmable segments for the heating profile.  
SPECIFICATIONS
 
Furnace Structure
 
  • Double layer steel casing with air cooling to keep furnace surface temperature lower than 60°C.

Max. Temperature 1700°C  ( < 1 hour )
Continuous Temperature 1600°C
Max. Heating Rate  <= 10°C /min (5C/min is recommended to avoid thermal-shocking the alumina tube)
Processing Tube
  • High purity Al2O3 ceramic, Purity > 99.9%; made in USA.

Temperature Accuracy +/ - 1°C
Flanges and Gas Inlet
 
One pair stainless steel vacuum flange are installed on two ends of the tube which allow high vacuum up to 10E-5 torr and 5 PSI positive pressure.
  • One solenoid valve is installed on the left of the flange for Hydrogen gas inlet. It connects with hydrogen detector. Once hydrogen gas leak is detected (10% below hydrogen explode point), gas inlet valve will be shut down immediately.
  • One pressure gauge is installed on the end of the gas inlet. Hydrogen gas pressure must be controlled under 5 PSI, which can be adjusted by a stainless steel needle valve.

Gas-outlet & Flowmeter 

  • One 16 -160 ml/min floating meter is installed on gas-outlet end for adjusting the gas flow rate.
  • 1/4" Dia stainless steel tube is installed for burning hydrogen gas during gas flowing.
  • One long lighter is included in the standard package for igniting hydrogen gas manually.
  • One 6" long neck flexes safe lighter is included for lighting hydrogen gas.
Hydrogen Detector System
      (included)
  • One Honeywell UL Approved Sensepoint Gas Detector is Integrated into the system.
  • Working Temperature Range:   40ºF to +149ºF (-40ºC to +65ºC)
  • Alarm Point:                            H2 Limited Explosive Line 20% (20% LEL).  Once detecting H2 gas beyond the point, it will shut off the inlet valve to the H2 automatically.

Warning

Click here to learn more about the installation of a gas regulator.

  • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
  • 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.
  • 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 ).
  • The hydrogen gas furnace must be placed under fume hood Please click here to view the spec of MTI EQ-FH-36 fume hood.
  • For first time buyer, Safe operation training is required at MTI facility with free of charge.
