Furnace Structure
|
- Double-layer stainless steel structure for maximum vacuum and safety, which can ensure a positive pressure up to 0.06MP and vacuum up to -0.1MPa
- Water cooling front door and air cooling shell
- Built-in pressure gauge, vacuum valves, and two gas float meters
- Built-in H2 burning control system --- if the controller detects no flame in the burner, the gas delivery valve will be shut down automatically
|
|
Inside Chamber
|
- Heated chamber: 400 x 400 x 400 mm (16x16x16 inch), 65 Liter (Max.)
- Energy-saving 1800 - grade fibrous alumina insulation
- Sealed by stainless steel with water-cooling
- Three sides heating ( Left right and back ) to ensure the best temperature uniformity.
- SiC plate is installed on the bottom, which has 100kg, Max. loading
|
Heating Elements |
- 9 sets of Mo coils heating elements are built-in and replaceable
- The Mo heating element is consumable. You may order spare element by click Pic. 1 below
- Warning: Mo heating element can not be used under air or oxygen at the temperature > 300°C
- The heating element can be replaced by 1900 grade MoSi2 to run the furnace under oxygen and air and Inert gases up to 1700 °C

Temperature Control
and
Processing control
|
- Temperature and processing control via touch screen computer, including
- .Temperature control with +/- 1 ºC accuracy.
- Two thermal couples are built-in: one for temperature control and one for safety monitoring
- 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
- Over-temperature protection by an independent controller
- Recording and display temperature profile during operation
- Processing control includes
- Purging procedure for the furnace chamber
- Chamber pressure control
- Gas flow control
- Recording and display pressure profile during operation
|
| Gas Flow Control and Vacuum Valve |
- Gas Flow Control and Vacuum Valve Two large flow meters (N2: 0~ 12L/min, H2: 0~12L/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
- The vacuum pump may be needed, but not included
|
H2 Gas Burning Control System
|
- An ignition device is 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 the operation facility to alarm for hydrogen leaking by accident. Please click the link below to order a hydrogen detector from us at extra cost.
|
Water Cooling
|
A 16L/min recirculating water chiller is installed in a bottom furnace for cooling the furnace's sealing flange.
|
|
Compliance
|
- CE Certified
- NRTL or CSA certification is available upon request at an extra cost.
|
|
Application Notes
|
- 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 an explosion in the worst-case scenario.
- 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 the furnace
- Exhausting Hydrogen gas in the room is forbidden.
