Audited Supplier | 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 fume hood which is not included. |
| Power | 4.0 KW Max. ( 30A breaker required) |
| Voltage | AC 208-240 Single Phase, 50/60 Hz |
| Max. Temperature | 1500°C ( < 1 hour ) |
| Continuous Temperature | 1400°C |
| Max. Heating Rate | <= 10°C /min |
| Processing Tube | Material: High purity Alumina 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 ins |
| Heating Zone length | 6" ( 152 mm) |
| Constant temperature zone | 80 mm (+/-2°C) |
| Temperature controller | PID automatic control via SCR (Silicon Controlled Rectifier) power control, e.g. current limiting phase angle fired the resistor with 51 steps programmable. Self-tuning and built in protection from overheated and broken thermal couple. Please click here to learn whySCR is more accurate than SSR (Solid State Relay) MET certified 30 programmable segments for precise control of heating rate, cooling rate and dwell time. Built in PID Auto-Tune function with overheating & broken thermocouple protection. Over temperature protection and alarm allows for operation without attendant(s). +/- 1 ºC temperature accuracy. RS485 Communications Port. |
| 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 |
| 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 10% (10% LEL). Once detecting H2 gas beyond the point, it will shut off the inlet valve to the H2 automatically. |
| Gas-outlet Flowmeter | One 16 -160 ml/min floating meter is installed on gas-outlet end for adjusting 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. Solenoid Value automatically shuts down the gas inlet in case of system failure |
