Compact Hydrogen Gas Tube Furnace for Laboratory up to 1500 ℃ with Hydrogen Detector

• 2.5  KW  Max. ( 20A breaker required)

• AC 208-240 Single Phase, 50/60 Hz

Working Temperature

• 1400 °C  continuous operation

• 1500 °C (< 1 hour )

Max. Heating Rate

≤ 10 °C/min

 Processing Tube

• Material: High purity Alumina Tube  

• Tube Size:  50 O.D x 38 I.D. x 700  Length. (mm )

• Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube.

(Ceramic blocks must be fully inserted into the furnace chamber before heating)

Heating Zone and

Temperature Uniformity

• 6" ( 152 mm) 

• 60 mm (± 2 °C) heating area with best temperature uniformity.

Temperature controller

• PID automatic control via SCR (Silicon Controlled Rectifier) power control.

• Self-tuning and built-in protection from the overheated and broken thermocouple. Please click here to learn why SCR is more accurate than SSR (Solid State Relay)

• MET certified 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.

• Over-temperature protection and alarm allow for operation without attendant(s).

• +/- 1 ºC temperature control during the dwelling.

• RS485 Communications Port.

• +/ - 1°C during the dwelling.

Flanges and Gas Inlet

• One pair of stainless steel vacuum flange is pre-connected for the two ends of the tube, which allows high vacuum up to 10E-5 torr and 5 PSI positive pressure.

• Two solenoid valves are installed on the left of the flange for the Hydrogen gas and N2 gas inlet.  It connects with a hydrogen detector.  Once hydrogen gas leak is detected (20% lower explosive limit (LEL)),H2  gas inlet valve will be closed and N2 gas valve will be opened,  and heating elements will be shut down immediately

• One pressure gauge and a needle valve is installed to control the Hydrogen gas pressure, which must be less than 0.03 MPa.

• One 0 -1000 ml/min floating meter is installed on the gas-outlet end for adjusting the 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.

• The solenoid valve automatically shuts down the gas inlet and heating elements in case of system failure.

One-year limited warranty for electrical and mechanical parts.  (Consumable parts such as sample plates and heating elements are not covered by the warranty, please order the replacement for related products below.)

ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of SUPSEMI One Year Limited Warranty.
