Product Description
Compact design with low-temperature stability
Eco-friendly recycling and cost-saving operation
The REXON SF6 Gas Reclaiming and Refilling Device is a critical tool for maintaining high-voltage electrical systems. It efficiently extracts used SF6 gas, removes contaminants such as moisture and decomposition products, and refills purified gas into equipment, restoring insulation performance. The device's advanced vacuum and compression systems guarantee thorough evacuation and precise gas filling, enhancing the reliability and safety of electrical apparatus. By enabling repeated reuse of SF6 gas, it reduces operational costs and minimizes environmental hazards. Compact yet durable, it is suitable for field maintenance, manufacturing, and installation tasks. Operators benefit from intuitive controls and real-time monitoring, ensuring consistent quality and protecting both equipment and personnel.
The REXON SF6 Gas Recycling and Refilling System is a professional, high-efficiency unit designed for the recovery, purification, drying, storage, and refilling of sulfur hexafluoride (SF6) gas used in electrical equipment. SF6 gas is widely applied in Gas-Insulated Switchgear (GIS), high-voltage circuit breakers, transformers, and other SF6-filled systems due to its excellent insulation and arc-extinguishing properties. However, SF6 is costly and can decompose into toxic by-products under arc or corona discharge conditions. Without proper recycling, this leads to financial losses, environmental hazards, and safety risks.
Developed according to JB/DQ2588-90 and DL/T 662-2009 standards, the REXON system integrates advanced international technologies, including liquefied refrigeration for high-efficiency gas recovery and a self-regenerative dry-type filter to ensure water content is reduced to below 40 ppm after primary reclaiming. The system can convert SF6 into liquid for compact, safe storage, and refilling, while maintaining gas purity for reuse.
The system is suitable for SF6 gas management during the production, inspection, installation, maintenance, and repair of electrical equipment, including:
Gas-Insulated Switchgear (GIS)
High-Voltage Circuit Breakers
Transformers and Power Substations
Other SF6-filled electrical apparatus
It enables factories and maintenance teams to recover residual SF6, remove harmful by-products, and safely store the gas for later reuse, achieving both economic savings and environmental protection.
Key Features & Innovations
