OTF-1200X-HPR-III High-Pressure Rocking Tube Furnace with Ni-Based Superalloy Tube, Up to 1100°C and 40 Bar Pressure
The OTF-1200X-HPR-III is engineered for precise heat treatment of materials requiring controlled high-pressure gas environments combined with elevated temperatures up to 1100°C. This furnace is particularly suited for processing alloys or compounds that tend to evaporate easily under normal atmospheric conditions, enabling advanced material synthesis and treatment under inert or oxygen atmospheres.
Its core component is a 2-inch diameter processing tube fabricated from a nickel-based superalloy GH747, capable of withstanding high temperatures and pressures. The furnace incorporates a rocking mechanism to enhance material uniformity during treatment, with adjustable angles and speeds controlled via an electric motor. The design includes three independently controlled heating zones for precise temperature profiling along the tube length.
Key Features
- Three heating zones totaling 450 mm with ±1°C temperature control accuracy using PID controllers.
- Ni-based superalloy GH747 tube (OD 60 mm, ID 52 mm, length 1000 mm) suitable for high-pressure and high-temperature operation.
- Rocking stage driven by a 150W DC motor with adjustable rocking angle from -30º to +90º and frequency from 0.1 to 1 cycle per minute.
- Maximum operating temperature of 1100°C (short term) and continuous operation at 1000°C.
- Maximum working pressures up to 40 bar at 800°C, decreasing with temperature to 8 bar at 1100°C.
- Integrated gas filtration and cold trap system to maintain gas purity and protect the furnace environment.
- Separated control panel with touch screen interface for safe and convenient operation of temperature, pressure, and gas flow.

Typical Applications
This furnace is ideal for heat treating and melting alloys or compounds that require a controlled high-pressure environment to prevent evaporation or decomposition. It supports research and development in materials science, metallurgy, and chemical synthesis involving reactive or volatile substances under inert or oxygen atmospheres.
Configuration & Operating Notes
The furnace includes eight fibrous alumina thermal blocks and stainless steel tubes to securely fix crucibles within the processing tube. Two CF flanges with copper O-rings and a metal hose are provided for high-pressure sealing and gas connection. Optional accessories include upgraded temperature controllers and spare copper O-rings. The system is designed for safe operation with a separated control panel and built-in alarms for over-temperature and thermocouple failure. Use only inert or oxygen gases; hydrogen and flammable gases are strictly prohibited.
