• AC 208-240 Single Phase, 50/60 Hz

Working Temperature

• 1400 ℃ continuous operation
• 1500 ℃ (< 1 hour)

Max. Heating Rate

• ≤ 10 ℃/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 to block heat radiation from the 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 ℃) heating area with the 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. Please click here to learn why SCR is more accurate than SSR (Solid State Relay)
• MET certified 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
• Over-temperature protection and alarm allow for operation without attendant(s).
• +/- 1 ℃ temperature control during the dwelling.
• RS485 Communications Port.
• Computer-access Temperature Control (Optional)
• MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package is available at the options bar.
• You may upgrade the temperature controller to the Eurotherm 3004 Temperature Controller which is compatible with LabVIEW. This package includes a Eurotherm 3004 programmer, and a communication cable (RS485 - USB). (Optional - LabVIEW program and OPC service are not included)

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.

Heating Element

• 1500 ℃ SiC Electric Heating Elements, 4 pcs.

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℃
