1500C Compact Hydrogen Gas Tube Furnace GSL-1500X-50HG Description
1500C Compact Hydrogen Gas Tube Furnace GSL-1500X-50HG is a compact hydrogen tube furnace designed for the heat treatment of oxidation-sensitive materials at temperatures up to 1500 ℃. Its 50 mm OD processing tube is constructed from pure alumina. To enhance safety measures, a Honeywell hydrogen leak detector and a solenoid valve are incorporated to shut off the hydrogen source and heating elements in the event of an H2 leak. Additional safety features include flange fixtures, quartz tube covers, and a double-layer steel furnace casing to protect in emergencies. The furnace is versatile, accommodating various inert gases as well as oxygen. With a precision temperature controller, users can establish their programmable heating profiles with up to 30 temperature segments.

Temperature Control
|
- +/ - 1℃ during the dwelling.
|
|
Flanges and Gas Inlet
|
- One pair of stainless-steel vacuum flange is pre-connected for the two ends of the tube, which allows high vacuum up to 10E-5 torr and 5 PSI positive pressure.
- Two solenoid valves are installed on the left of the flange for the Hydrogen gas and N2 gas inlet. It connects with a hydrogen detector. Once a hydrogen gas leak is detected (20% lower explosive limit (LEL)), the H2 gas inlet valve will be closed and N2 gas valve will be opened, and heating elements will be shut down immediately
- One pressure gauge and a needle valve are installed to control the Hydrogen gas pressure, which must be less than 0.03 MPa.
|
|
Hydrogen Detector System
|
- One Honeywell UL Approved Sense Point Gas Detector is Integrated into the system.
- Working Temperature Range: 40ºF to +149ºF (-40℃ to +65℃)
- 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 and heating elements automatically.
|
|
Gas-outlet Flowmeter
|
- One 0 -1000 ml/min floating meter is installed on the gas-outlet end to adjust the gas flow rate.
- 1/4" Dia stainless steel tube is installed for burning hydrogen gas during gas flow.
- One long lighter is included in the standard package for igniting hydrogen gas manually.
- The solenoid valve automatically shuts down the gas inlet and heating elements in case of system failure.

Warning
|
- The tube furnaces with alumina tubes are designed for use 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.
- Never heat the furnace while the gas release valve is closed and a positive pressure shall be kept within the furnace chamber.
- The flow rate for gasses should be limited to < 200 SCCM (or 200ml/min)
- The hydrogen gas furnace must be placed under the fume hood.
- Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500℃
