OTF-1200X-S-SB High-Pressure Fluidized Bed Furnace Reactor with 12mm ID Nickel-Based Super-Alloy Tube
The OTF-1200X-S-SB is engineered for laboratory fluidized bed reactor applications requiring precise control of temperature and pressure. It supports fluidized bed processes at temperatures up to 1100°C and pressures up to 3 bar (0.3 MPa), making it suitable for advanced material synthesis and catalytic studies under elevated conditions.
This vertical single-zone furnace incorporates a nickel-based super-alloy tube with a 12 mm internal diameter and 600 mm length, designed to withstand high temperatures and corrosive environments. The tube is equipped with flanges and a mechanical pressure gauge, along with a safety relief valve that activates automatically at 0.3 MPa to ensure safe operation. A nickel alloy mesh inside the tube supports layered material loading for fluidization.
Key Features
- Operating temperature up to 1100°C with continuous operation at 1000°C.
- Maximum working pressure of 3 bar with option to increase to 10 MPa by removing the powder feeder and adding high-pressure fittings.
- 200 mm heating zone length with K-type thermocouple for accurate temperature measurement.
- Secondary powder feeder with three separate 50 ml zones connected via KF25 ports for simultaneous multi-material feeding.
- Double-layer steel furnace structure with fibrous alumina insulation and air cooling for thermal efficiency and durability.
- Separated temperature control unit with programmable segments and built-in PID auto-tune for precise thermal management.
- Safety features including mechanical pressure gauge and automatic safety relief valve activation at set pressure limits.

Typical Applications
This furnace reactor is ideal for fluidized bed catalytic reactions, material synthesis under controlled atmospheres, and high-temperature gas-solid interactions at elevated pressures. It supports layered powder feeding for complex reaction studies and can be adapted for higher pressure applications by modifying fittings.
Configuration & Operating Notes
The system includes a secondary powder feeder with three separate zones connected via KF25 ports, limited to 3 bar maximum pressure. Removing the feeder and installing high-pressure fittings can increase the maximum working pressure up to 10 MPa. A two-stage pressure regulator must be installed on the gas supply to limit pressure below 3 PSI for safe operation. Optional accessories include a Eurotherm 3000 temperature controller with ±0.1°C accuracy and a laptop-based LabVIEW control system for advanced temperature profile management.
