Heating Zone and

Tempearture Uniformity

• 6" ( 152 mm) 

• 60 mm (± 2 °C) heating area with best temperature uniformity.

• 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 ºC temperature control during 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. Click for the detail information about the MTS02-Y software kit. 

  • 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)

• +/ - 1°C during dwelling.

• 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 valvs are installed on the left of the flange for Hydrogen gas and N2 gas inlet.  It connects with hydrogen detector.  Once hydrogen gas leak is detected (20% lower explosive limit (LEL)),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 is installed to control the Hydrogen gas pressure, which must be less than 0.03 MPa.

Left flange side	Right flange side

• 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 and heating elements automatically.

• One 0 -1000 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 and heating elements in case of system failure.
•           

• 1500 °C SiC Electric Heating Elements ,  4 pcs. ( click picture below for detailed specs )
  

• Brand new laptop with Microsoft Window 10 and Microsoft Office 2013 (30 days free trial) for immediate use.
• Labview Based Temperature Control System (EQ-MTS01) enables user to edit temperature profile, manage heat-treatment recipe, record and plot data for MTI furnaces.
• A wireless remote control provides up to 300 meters operating range.
• Above features are available upon request at an extra cost (up to $1,000). Please contact us for more information.
• Note: The software is only compatible with MTI’s Yudian Temperature Controller

•     

• CE Certified

• The tube furnaces with alumina tube 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. Click here to learn the installation of a gas regulator. 
• Never heat the furnace while the gas release valve is closed and a positive pressure shall keep 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 fume hood Please click here to view the spec of MTI EQ-FH-36 fume hood.
• Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
