VEF-1100-64-L Large Molten Salt Electrolytic Reactor with 1100°C Max Temperature and Moveable Electrodes
The VEF-1100-64-L reactor is engineered for advanced molten salt electrolysis applications, including molten salt electrolytic graphitization (MSEG). It provides a controlled environment for high-temperature reactions within a spacious hermetic chamber, enabling precise atmosphere management essential for sensitive electrochemical processes.
This system supports continuous operation up to 1000°C and peak temperatures of 1100°C, with a uniform temperature zone of 300 × 300 × 300 mm maintained within ±2°C. The reactor incorporates a manual vertical travel mechanism for loading and retrieving electrodes through an air-tight flange, accommodating electrodes with a diameter of 12.7 mm. The design facilitates safe and efficient electrode handling before and after electrolysis.
Key Features
