Personalization


GSL-1700X-100VT-UL is UL/CSA ready to pass furnace. This high temperature vertical tube furnace is using MoSi2 as heating elements and 4" diameter high purity alumina tube. It is designed for heat treatment of all types of new materials under vacuum or other gases condition up to 1700oC. The temperature of GSL-1700X-100VT  tubing furnace is controlled by high precision SCR power controller with accuracy +/-1 oC and 30 segments programmable up to 1700oC (3092 oF).

Temperature Controller

  • 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 attendant.
  • +/- 1 ºC temperature accuracy.
  • RS485 Communication Port
  • Optional:  
    • The furnace may be operated by PC by installing a control module. Please order a 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.

Warning

 

MoSi2 heating element is used in high temperature under an oxidizing atmosphere. During the oxidizing process, the SiO2 protective film is formed again the heating element from melting during sustained use. The MoSi2 heating element must not be used in the temperature between 400 oC and 700 oC for a long time, otherwise the element will be cremated under the strong oxidizing atmosphere at low temperatures.
