Furnace Structure
|
-
Double-layer stainless steel structure for maximum vacuum and safety
-
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
|
|
Heated Chamber
|
- Volume: 200 x 200 x 200 mm (8 x 8 x 8 inch), 8 Liter

Alarm Functions
- Over-Temperature Alarm
- Deviation Alarm
- Thermocouple-Break Alarm
- Furnace Chamber Pressure Alarm
- Water-Chiller Alerts:
- Low-Water-Level Alarm
- Flow-Restriction Alarm
- Pipeline Overpressure Alarm
- High-Temperature Warning

Protection Features
- Overcurrent Protection
- Overvoltage Protection
- Leakage Protection
Automatic Furnace-Chamber Cleaning
- The vacuum pump and the gas-inlet system switch automatically, number of cleaning cycles is programmable
- Manual Mode available
Constant-Pressure Sintering Mode
- Automatically regulate the intake and exhaust flow rates to maintain a slight positive pressure inside the furnace throughout the heating cycle.
- Constant-pressure range: 105 000 Pa – 115 000 Pa.
Dual Explosion-Proof Settings (Pressure Control)
- An electronic pressure transmitter is used to monitor exhaust pressure. When the chamber pressure exceeds the preset exhaust-pressure setpoint, the exhaust valve opens to accelerate venting.
- A mechanical, explosion-proof relief valve is mounted at the top of the furnace chamber; it is set to open at 0.04 MPa
Electrical Components
- All Electrical Components, Cables, and Cold-Pressed Terminals Use ABB Products

Data Acquisition and Recording
|
- Temperature-curve data acquisition and logging
- Pressure-variation-curve data acquisition and logging
- All collected data is automatically saved to the local hard drive
|
|
Connectivity
|
- Standard Ethernet port
- Supports LAN and Internet connection for remote control and monitoring

Heating Elements
Mo Coil

MoSi2
|
- 6 sets of Mo coils heating elements are built-in and replaceable
- The heating element of the Mo coil is consumable parts which should be ordered separately if extra is required. (click the pictures left to order spare)
- The heating element can be replaced by MsSi2 to run the furnace under oxygen and air up to 1700°C (order picture below right to order spare)
- Warning: Mo heating element cannot be used under air or oxygen at the temperature > 300°C
|
Gas Flow
|
- Two 12 L/min float flowmeters, each independently controlling one of the two air inlet lines.
- One for purging Inert gas prior to introducing H2 gas
- One for controlling H2 gas flow
|
H2 Gas Burning Control System and 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
- Hydrogen detector is to Enhanced safety for MTI Hydrogen Gas Tube Furnace
|
|
Water Cooling
(Optional)
|
- Chilled water is required.
- MTI recommend using a 58 L/min recirculating water chiller
|
|
Vacuum Pump
|
- Vacuum pump is required
- MTI recommend using a 240 L/min rotary vane pump or equivalent.
|
|
Compliance
|
- CE Certified
- NRTL or CSA certification is available upon request at the extra cost

Application Notes
|
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 a 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 safety operation training. Any damages caused by the corrosive and acidic gases are not under the coverage of the MTI One Year Limited Warranty.
