• 
       •  Double layer steel structure with air cooling to keep case temperature < 65^oC.
•      •  Vertical and splittable for easy installation.
•      •  The tube is sealed by a gate valve at the bottom flange. For quenching, open the gate valve and let the sample drop
           directly into the liquid container by activating the electromagnetic sample release.
  
•      •  Operation control made easy with a newly designed electric gate valve.
  
•      •  Electromagnet sample release flange with water cooling is included.

Electromagnet Sample Release Flange
&
Quenching Media Tank

• 
       •  Fully 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.
•      •  Improved top flange design allows easy sample reload without uninstalling all parts of the flange.
  
•      •  Bottom flange is connected with a 4" gate valve ( electrically operated ) via CF-100 adaptor.
•      •  The gate valve is connected with a quenching media container in size 400 L x400 W x 200 H mm.
•      •  Caution: You must use ice water or cooled oil as quenching agent if quenching under vacuum.

• 
       •  In order to obtain accurate temperature inside tube furnace, you shall calibrate temperature before use, please click here to learn how.
•      •  How to set up the ceramic tube and vacuum flange for MTI Tube Furnace.
•      •  The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI
•      •  Never use graphite crucible in the alumina tube.
•      •  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 condition exists within the furnace chamber.
          The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process;
           please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable
           damages.
•      •  The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
•      •  Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
