Furnace Structure |
- Double-layer steel case with two cooling fans, which ensure low surface temperature;
- Energy-saving high purity fibrous alumina insulation;
- Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating
- Split cover with interlock protection
- Quartz block (Optional) is ideal for more cleanness and a higher achievable vacuum.

- 1000°C under vacuum
- Max. Heating Rate: 20°C/min
|
Temperature Controller |
- 3 digital temperature controllers certified by MET and CE Certified
- PID automatic control with 30 programmable segments for control of heating & cooling rate and dwell time.
- Built-in overheating & broken thermocouple protection.
- Over-temperature protection and alarm allow for operation without attendant(s).
- +/- 1 ºC temperature accuracy.
- RS485 Communications Port.
- Optional:
- The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at an extra cost.
- If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us to avoid software installation problems.
|
Eurotherm Temperature Controllers (optional upgrade) |
- 1 heating channel
- 1 program of 8 or 24 segment
- Alarm Relay: Form 'A' and Form ‘C’ built-in
- Digital Communications: RS485
- Temperature Accuracy: ± 0.1ºC
- Recipes: Using a PC tool recipes can be created that can be used to change the operating parameters of the 3000 simply by selecting a new recipe via the HMI. This is very useful where multiple products are processed using the same controller but require different parameters to be set.
|
Flange Fittings |
- One pair of SS 304 vacuum flange with double high-temperature silicone O-ring is Included
- 2 needle valves are installed with flange
- One Vacuum/ pressure gauge is installed one side flange
- The vacuum level: 10-2 torr by the mechanical vacuum pump and 10-5 torr by the turbopump.
- Optional: You may choose flange with a KF25 vacuum port for a faster and better vacuum, and click the picture below to order a vacuum pump separately
- You may order flange support to avoid tube rotating
