- • Advanced Temperature Control (Optional)
- º MTS02-Y Temperature control software kit (for YD518P series controllers) + 15"
laptop package is available at the options bar. Click for the detail information about
the MTS02-Y software kit. - º You may upgrade the temperature controller to the Eurotherm 3504 Temperature
Controller which is fully compatible with LabVIEW. This package includes a Eurotherm
3504 programmer, a communication cable (RS485 - USB) and a software CD.

Gas Flow Control and Vacuum Valve
|
• Two large flow meters (N2: 0~3.5L/min, H2: 0~3.5L/min) are installed in the front panel of the
furnace.- • One for purging Inert gas prior to introducing H2 gas
- • One for controlling H2 gas flow
- • KF40 vacuum pumps built-in to connect a vacuum pump
- • Vacuum pump may be needed, but not included
|
H2 Gas Burning Control System
 |
• 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 local store, please click link below to order hydrogen
detector from us at extra cost.

Warranty
|
• One year limited warranty with lifetime support. (Consumable parts such as sample plates and
heating elements are not covered by the warranty, please order the replacement at related
products below.)- • ATTENTION: Any damages caused by the use of corrosive and acidic gases are not
under the coverage of MTI One Year Limited Warranty.
Attention: A free course of safety operation training at MTI field is required to purchase this furnace. A customer's side training is also available upon request at extra cost. If the users believe that they have sufficient experience and knowledge to handle the furnace in the dangerous or emergent situation, a liability release agreement must be signed at the purchase. MTI Corp. is not responsible for any damages caused by misuse without the safety operation training. Any damages caused by the corrosive and acidic gases are not under the coverage of the MTI One Year Limited Warranty.

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 safety 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 0.01-0.02 Mpa above the
standard atmospheric pressure during the entire heating process, otherwise, the oxygen in the
air may backflow into the furnace chamber and cause explosion in the worst case scenario. - • Pressure over 0.02Mpa or below -0.05Mpa (Relative Pressure) is strictly prohibited.
- • ALWAYS place the furnace in a room with the 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.
- • Must be used under inert gas or hydrogen gas environment
- • 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 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 gas cylinder to limit the
pressure to below 3 PSI for safe operation.
