2.375" x 40" (60.5 OD x 51.5 ID x 1000mm L)

3.15" x 40" (80 OD x 74 ID x 1000mm L)

This model of furnaces have passed the UL61010 or SPE 1000 certification and are currently in stock. No extra certification fee. Certificate report will be sent along with the furnace. 

• Double layer steel casing with air cooling.   
• Two cooling fan inside to keep  case temperature < 55ºC.  
• High purity Alumina refractory chamber with 10mm thick 2500ºC grade YSZ ceramic liner.  

• PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.
• 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
• Please click here to learn why SCR is more accurate than SSC (Solid state relay).
• Built-in over temperature alarm and protection allows for operation without an attendant.
• +/- 1 ºC temperature accuracy.
• RS485 Communication Port.
• Optional:  
• The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at extra cost.  
  
• If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer (laptop) from us to avoid software installation problems. For more information please click here.

• How to set up ceramic tube and vacuum flange for MTI Tube furnace 
• Proper placement of tube blocks
• The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
• Attention: A two stage pressure regulator must be installed on 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 unforseeable damages.
• The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
• Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up t
