Click to enlarge
In stock
Item Number: GSL-1500X-42HG
 GSL-1500X-42HG tube furnace is designed for processing material under hydrogen gas up to 1500°C safely. The processing tube is made of 42 mm OD alumina, and one hydrogen gas detectoe is included which will shutdown hydrogen gas via a built in solenoid valve immediately once detecting hydrogen gas leaking   Also the furnace can be used for all kind of inert gases and oxygen gas .  Precision temperature controller is 30 segment programmable.  .
Specifications:
 
Furnace Structure
  • Double layer steel casing with air cooling to keep furnace surface temperature lower than 60°C. 
  • High purity fibrous alumina insulation for Max. energy saving.

  • Hydrogen detector and solenoid valve are included for safe operation

  • The hydrogen gas furnace must be placed under fume hood which is not included > If you don't have a fume hood, please order from a professional vendor.

Processing Tube

·       Material: High purity Alumina Tube max. 1600°C working temperature  

·        Tube Size:  42 O.D x 38 I.D. x 700  Length. (mm )

·         Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)

 
Heating Zone length 6" ( 152 mm) 
Constant temperature zone 80  mm (+/-2°C)
Temperature controller
 
  • PID automatic control via SCR (Silicon Controlled Rectifier) power control, e.g. current limiting phase angle fired the resistor with 51 steps programmable.                                                     
     
  • Self-tuning and built in protection from over-heated and broken thermal couple. Please click here to learn why SCR is more accurate than SSR (Solid State Relay)
  • Optional:   PC control interface & Software is available at extrat cost, click picture below to see detail specs and order separately
Temperature Accuracy +/ - 1°C
Flanges and Gas Inlet
 
     
  • One pair stainless steel vacuum flange are installed on two ends of tube which allow high vacuum upto 10E-5 torr and 5 PSI positive pressure.
  • One solenoid valve is installed on left of flange for Hydrogen gas inlet. It connects with hydrogen detector.  Once hydrogen gas leak is detected ( 10% below hydrogen explode point ), gas inlet valve will be shutdown immediately
  • One pressure gauge is installed on the end of gas inlet.  Hydrogen gas pressure must be controlled under 5 PSI, which can be adjust by a stainless steel needle valve.
