Flanges and Gas Inlet

Two sets of CF-63 flanges are welding on two ends of the tube which allow high vacuum up to 10E-5 torr and 30 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 gas inlet.  Hydrogen gas pressure must be controlled under 5 PSI, which can be adjust by a stainless steel needle valve

Hydrogen Detector System

Gas Detector is Integrated into the system.
Working Temperature Range:   40ºF to +149ºF (-40ºC to +65ºC)
Alarm Point: H2 Limited Explosive Line 10% (10% LEL).  Once detecting H2 gas beyond the point, it will shut off the inlet valve to the H2 automatically.

Warranty

One year limited warranty for electrical and mechanical parts.

Laptop, software & WiFi Control (Optional)

Labview Based Temperature Control System enables user to edit temperature profile, manage heat-treatment recipe, record and plot data for CY furnaces.
A wireless remote control provides up to 300 meters operating range.
Above features are available upon request at an extra cost . Please contact us for more information.
Note: The software is only compatible with CY’s Temperature Controller

Warning

Tube furnaces with alumina tubes are designed for using under vacuum and low pressure < 0.12 atm (absolute pressure)
The flow rate for gases should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
Attention: A two-stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation.
Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°.
