|
| Hydrogen Burning System |
- One Hydrogen burnoff column is built in left flange
- An ignition device already installed to incinerate flowing gas and detect burner temperature to ensure H2 burner is in working condition. If H2 does not burn properly, the controller will shut down the H2 gas delivery valve immediately.
- Warning: You must install a certified Hydrogen detector in operation facility to alarm hydrogen leaking b accident. If you can not find in the local store, please click the link below to order 3M hydrogen detector from us at extra cost.

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 10% (10% LEL). Once detecting H2 gas beyond the point, it will shut off the inlet valve to the H2 automatically.
|
| Optional |
- The tube furnace should be calibrated regularly to maintain the temperature accuracy and uniformity. We are providing a simple calibration kit for you to complete this job at extra cost
- You may consider to order turbo pump for hi-vacuum upto 10-6 torr ( click pic below right to order )
- You may use precision gas delivery system to deliver H2 gas at constant flow
- If using water cold flange you may need a recirculating water chiller.
|
