1100C Hydrogen Gas Tube Furnace with 5" Quartz Tube with H2 Detecting System - OTF-1200X-S5-H2


In stock
Item Number: OTF-1200X-S5-H2
Transported by LTL Freight (Truck)

OTF-1200X-S-5-H2 is a single zone hydrogen tube furnace for the heat treatment of oxidation-sensitive materials up to 1100 ℃. The 5” processing tube is made of high-quality fused silica. The hydrogen detecting system comes with a Honeywell hydrogen gas detector, two solenoid valves, and an alarm siren. In case H2 leak is detected, the special design automatically activates the siren, cuts off the hydrogen source, shuts down the power, and purges nitrogen. It can also avoid air backflow if a power outage happens. Flange fixtures, full quartz tube covers, and double-layer steel furnace casing are installed to provide additional safety protection in case of emergency. The furnace is also compatible with all kinds of inert gasses as well as oxygen. The precision temperature controller provides customers to set up their own programmable heating profiles with up to 30 temperature segments.

Flanges and Fittings
              
Left Flange     Right Flange

  • 5" flanges with quick load-lock doors for fast sample loading and retrieving. 
  • The water-cooled flange is available at an extra cost.
  • Left flange assembly:
                              Mechanical pressure gauge
                                      Needle and solenoid valves
                                      1/4" thermocouple feedthrough
                                      Two 1/4" tube fittings
  • Right flange assembly:
                               H2 torch
                                      0-1000 ml floating flow meter
                                      Hydrogen torch
                                      Gas-outlet valve
  • Full tube covers and flanges fixtures to avoid hydrogen hazards in case of emergency or explosion. 
  •                      
Hydrogen Detecting System
      (included)
  • One Honeywell UL approved sense point gas detector is Integrated into the system.
  • Working Temperature Range: -40 ºF to +149 ºF (-40ºC to +65ºC)
  • Alarm Point: H2 Lower Explosive Limit (LEL) is set at 20%. Once H2 gas is detected beyond the limit, it will cut off the hydrogen source, turn off the heating elements, and purge nitrogen.
  • Power outage protection: if the furnace encounters a power outage, hydrogen source and heating elements will be cut off, and start to flow nitrogen.

Flow Meter and Hydrogen Torch

 
  • One 1000 ml/min floating flow meter is installed on the gas-outlet end to adjust the flow rate.
  • 1/4" stainless steel tube is installed as hydrogen torch to burn out the exhaust.
  • One lighter is included in the standard package for igniting hydrogen gas manually.

  • Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.12 atm (absolute pressure)
  • The flow rate for gases should be limited to < 200 SCCM for reducing thermal shocks to the tube
  • 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.
  • Vacuum limit for all quartz tube furnaces: * furnace operation under vacuum is up to 1000 °C
