Two-Zone Rotary Furnace
|
- Working temp: 1200ºC Max(<1hrs)., and 1100ºC for continuous heating
- Two PID temperature controllers with 30 segments programmable.
- Input Power: 208 – 240VAC, a single phase at max. 2.5KW.
- High purity Alumina fibrous insulation for max. energy saving
- Gear DC motor drives quartz tube with variable speed 2 - 10 RPM
- The split cover enables faster cooling and easy operation
- Two zones: each zone length 8" (200 mm), total 16" (400 mm) heating zone
- Constant temperature zone: 200 mm within +/-1oC if two zones at the same temperature.

Quartz Tube

|
- Standard: 4'' O.D Fused quartz processing tube, please click the pic on the left for details
- One pair of 60mm SS sealing flange with rotatable gas connector needle valves and are included for immediate use
|
Sealing Flanges
|
- A pair of 1'' O.D quick disconnect flange with KF25 port are installed on each end of the tube
- Magnetic fluid seal swivel coupling is used to enable the tube rotation without twisting.

MFC Gas Mixing Station
|
-
Four precision mass flow meters (0.02% accuracy) with digital displays are installed on the bottom case to control the gas flow rate automatically.
- MFC 1: Gas flow range from 0~100 SCCM
- MFC 2&3: Control range from 0~200 SCCM
- MFC 4: Control range from 0~500 SCCM
- Gas inlet/outlet fittings: 6mm O.D tube fitting
- Power: 208-240VAC 50/60Hz
- Stainless steel needle valves for manual ON/OFF control of gas supply.
- Large PLC touch screen control enables easy flow rate settings

|
- Two heating zone design with individual temperature controller
- Precise PID control of heating, cooling rate and dwell time, 30 programmable segments for
- Built-in overheating & broken thermocouple protection.
- Over-temperature protection and alarm allow for operation without attendant(s).
- +/- 1 ºC temperature accuracy.
- Three K-type thermocouples (one for each zone).
- RS485 Communications Port.
- Optional:
-
- The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at 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. For more information please click here.

Volumetric Feeder and Collector Tank (Optional)
|
-
EQ-PF-1S automatic feeder includes a motor-driven agitator and stainless steel hopper with a built-in vibrator. It is designed for feeding solid powder into a furnace for continuous firing/heat treating. Please click the pic.1 on the left to order.
- Stainless steel collection tank ( 2 Liter Capacity ) can be installed on the other end of processing tube to gather the fired powder without exposure to air. Please click the pic.2 on the left to see details
- You may add a vacuum gate valve on the top of the sample collecting tank for air-sensitive material. (Pic 3)
