Product Description

GSL-1500X-50HG-AM is a fully-automated compact hydrogen tube furnace for the heat treatment of oxidation-sensitive materials up to 1500℃. The 50 mm OD processing tube is made of pure alumina. The flammable exhaust burning module automatically ignites, detects, and controls the hydrogen gas flow. A Honeywell hydrogen leak detector is used to cut off the hydrogen source and heating elements once the H2 leak is detected.

Flange fixtures, quartz tube covers, and double-layer steel furnace casing are installed to provide additional safety protection in case of emergency. The furnace is also compatible with all kinds of inert gasses as well as oxygen. The precision temperature controller provides customers to set up their own programmable heating profiles with up to 30 temperature segments.

Product Parameters

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. • Hydrogen detector and solenoid valve are included for safe operation • The hydrogen gas furnace must be placed under a fume hood which is not included.
Power	• 4.0 KW Max. ( 30A breaker required) • 208-240 VAC Single Phase, 50/60 Hz
Working Temperature	• 1400 °C continuous operation • 1500 °C (< 1 hour )
Max. Heating Rate	<= 20°C /min
Processing Tube	• Material: High purity Alumina Tube • Tube Size: 50 O.D x 38 I.D. x 700 Length. (mm ) • Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. • (Ceramic blocks must be fully inserted into the furnace chamber before heating)
Heating Zone and Temperature Uniformity	• 6" ( 152 mm) • 60 mm (± 2 °C) heating area with best temperature uniformity.
Temperature controller	• PID automatic control via SCR (Silicon Controlled Rectifier) power control. • Self-tuning and built-in protection from the overheated and broken thermocouple.

Flanges and Gas Inlet	• One pair of stainless steel vacuum flanges with silicone o-rings is pre-connected for the two ends of the tube, which allows a high vacuum up to 10E-5 torr and 5 PSI positive pressure. • Mechanical Pressure Gauge • Mass flow controller: 0-1000 ml • Two solenoid valves and a check valve to control the gas inlet of the hydrogen and inert gases. • The two-stage regulator is required but not included for gas cylinders.
Flammable Exhaust Burning Module	• Automatic ignition system: hydrogen gas is self-ignited by the filament at the exhaust to prevent an unstable flame from the small flow rate and inevitable air disturbance. • Over-pressure protection: The pressure relief line will be open automatically if pressure is over 0.1 MPa. The hydrogen inlet and heating element will cut off as well. If the automation system fails, the mechanical pressure-relief valve will be open if pressure is over 0.15 MPa. • Pirani pressure gauge. • Flow detection: If the gas flow is not detected, the alarm will be activated to cut off the gas & power source. • Filament status monitoring: A mutual inductor is installed to monitor the working status of the filament. Once the filament passes its working lifetime, the user will receive a notification to change the filament.
Heating Element	1500 °C SiC Electric Heating Elements, 4 pcs.
Hydrogen Detector System	• 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.
