1000C Max 4" SS Tube Hydrogen Vertical Quenching Furnace - OTF-1200X-VT-100-VTQ-HG

0.0/5 rating (0 votes)


OTF-1200X-VT-100-VTQ-HG is a split Hydrogen Tube Furnace with a vacuum-sealed 100mm (4") OD stainless steel tube and liquid quenching tank, which is designed for quenching samples from high temperature ( Max. 1000°C) to ice water or oil to study material phase transition and microstructure.


 Furnace Structure
  • Double-layer steel structure with air cooling to keep case temperature < 65oC
  • Vertical and splittable for easy installation.
  • Liquid quenching tank is connected to a 4" quartz tube via a gate valve and allow sample drop to the liquid container

 3 KW


 AC 208-240V Single Phase, 50/60 Hz

 Max. Temperature

 1000oC < 1 hrs

 Continuous Temperature

 900oC < continuous

 Max. Heating Rate

 <= 20oC /min, recommended heat: <= 10oC /min

Tube Size and Materials

  • One 101 OD x 92 ID x 1000L mm (4" x 40") Stainless Steel Tube is included

Heating Zone

  • Heating Zone length:   440mm 
  • Constant Temperature:       150 mm ( within+/- 1oC)

Temperature Controllers

  • 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
  • Built-in PID Auto-Tune function with overheating & broken thermocouple broken protection.
  • Over-temperature protection and alarm allow for operation without attendant(s).
  • +/- 1 ºC temperature accuracy.
  • One K-type thermocouple.
  • RS485 Communications Port.

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 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 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.
Electromagnet Sample Release Flange & Quenching
  • Full automatic electromagnet sample release flange
  • Hinged plate hooks the cable, which pulls the sample.
  • Hinged plate drops when the electromagnet powers off. The sample and the cable fall into the quenching tank.
  • Rings are available for hanging the tube block with cables.
  • Bottom flange is connected with a 4" gate valve ( manual operated ) via CF-100 adaptor
  • The gate valve is connected with a quenching media container in size 400 x400 x 200 H ( mm )
  • Caution: You must use ice water or cooled oil as a quenching agent if quenching under vacuum.

Gas Purification and Circulation
  • EQ-RMP-1 is an automatic recirculating moisture and oxygen purification system, which can provide an environment with moisture and oxygen concentration lower than 1 ppm for MTI's furnaces and gloveboxes. 
  • Two-columns of Molecular sieves are Built-in in the system. One is for removing oxygen and another is for removing moisture up to < 1 PPM
  • The automatic pressure control system is built in to keep the pressure at a constant level
  • 6" color PLC touch panel is included which can set and display the humidity and pressure level
  • Oxygen sensors and moisture sensors are included. 
Hermetic Quenching Tank
  • Hermetic quenching tank is optional for air-sensitive materials, which enables the entire quenching process under atmosphere control
  • Please contact MTI for further inquires.
