and performs advanced functions of:- High accuracy temperature control
- Secondary temperature monitor and alarm
- Pressure control and alarm
- Data acquisition/analysis and graphical recording
- TCP/IP communications
- Eurotherm software included
- A 15.6-inch screen laptop is included in the package. The Eurotherm software is installed and configurated.
|
Gas Flow Control and Vacuum Valve
|
• Two large flow meters (N2: 0~3.5L/min, H2: 0~3.5L/min) are installed on the front panel of the
furnace.- • One for purging Inert gas prior to introducing H2 gas
- • One for controlling H2 gas flow
- • One heavy-duty vacuum pump ( CE certified ) built-in bottom furnace.
You may choose a UL certified pump at extra cost ( Pls click picture below to see specs)
 ( CE certified )  ( TUV certified )
|
H2 Gas Burning Control System
and Option Hydrogen detector
|
• An ignition device already installed to incinerate flowing gas and detect burner temperature to
ensure H2 burner is in working condition. If H2 does not burn properly, the controller will shut
down the H2 gas delivery valve immediately.- • Warning: You must install a certified Hydrogen detector in operation facility to alarm hydrogen
leaking b accident. If you can not find in a local store, please click the link below to order
hydrogen detector from us at extra cost. - • Option Hydrogen detector to Enhanced safety for MTI Hydrogen Gas Tube Furnace

Application Notes
|
• Please EXERCISE EXTREME CAUTION. H2 gas is highly flammable and explosive. H2 ignites
at a temperature of 400°C, an explosion could occur when the hydrogen content reaches
4.0%-74. 2% in the air, please strictly follow the rules below to for safe operation.- • Inert gas MUST be used to purge the furnace chamber to eliminate all the air before introducing
the H2 gas. - • The pressure inside the chamber should ALWAYS be controlled at around 0.01Mpa above
during the entire heating process, otherwise, the oxygen in the air may backflow into the
furnace chamber and cause the explosion in the worst-case scenario. - • Pressure over 0.02Mpa (Relative Pressure) is strictly prohibited.
- • ALWAYS place the furnace in a room with a fume hood and a hydrogen detector installed.
- • Good ventilation is necessary for the room in which place the furnace
- • Exhausting Hydrogen gas in the room is forbidden.
- • For preserving the longevity of the furnace components, we recommend the heating rate not to
exceed 10 °C /min. - • Small cracks may appear on the surface of the refractory ceramics over extended use.
This is a normal occurrence and the cracks may be repaired with alumina coating. - • Please click here to learn how to DIY gas purging system.
- • The refractory block must be inserted before the closing door.
- • Please Click Underline to learn "Max. Working Temperature of Heating Elements of Tungsten,
Tantalum, Molybdenum Under Various Processing Gases". - • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit
the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas
regulator.
