RF-391 Large-scale SF6 Recovery Unit

Facing the gas treatment requirements of SF6 electrical equipment and switch rooms, RF-391 Large-scale SF6 Recovery Unit takes “integration, high efficiency, and compliance” as the core to create a professional service system covering the whole process, becoming a reliable assistant for the stable operation of the power system.

1. Full-function Integration, Say Goodbye to the Troubles of Multi-device Collaboration

There is no need to match multiple devices. RF-391 can handle five core requirements in one stop:

• Vacuum Pumping: The PLC interface displays the real-time change of vacuum degree. The operation is transparent and controllable, and the pumping process is accurately visible.
• Gas Recovery: The recovered gas can be flexibly stored in the on-board storage tank or external cylinders, adapting to different on-site storage conditions.
• Gas Refilling: The RF-391 Large-scale SF6 Recovery Unit supports two modes of “pressure-regulating direct filling” and “gas/liquid phase compression filling”, meeting the diverse refilling needs of switchgear and pressure vessels.
• Cylinder Compression: Efficiently compress the recovered gas to improve storage utilization.
• Vaporization Output: Adapt to the gas form requirements under different working conditions without the need for additional vaporization equipment.

2. Hardcore Performance, Balancing Efficiency and Safety

Designed based on the DL/T 662 standard, RF-391 ensures the reliability of operations with details:

• Efficient Recovery: With the support of negative pressure recovery technology, the recovery efficiency is significantly improved, reducing SF6 gas loss.
• Purity Assurance: The RF-391 Large-scale SF6 Recovery Unit is equipped with a precision filtration system to simultaneously remove moisture, decomposition products, and particulate matter, ensuring gas purity.
• Safety Protection: The vacuum pump is equipped with an anti-backflow valve to avoid reverse flow damage to the equipment. The independent storage tank + gas heating system ensures stable operation in low-temperature environments.
• Rapid Filling: The filling efficiency of liquid SF6 reaches “50kg in a 40L cylinder only takes 5 – 8 minutes”, greatly shortening the operation time.

3. Flexible Adaptability, Coping with Diverse Global Working Conditions

Whether your operation scenario is in the frigid zone or the tropics, RF-391 can perform stably:

• Multiple cooling methods are available, perfectly adapting to different global climate conditions.
• The semi-closed protective structure + modular design not only has strong anti-interference ability but also is convenient for later maintenance – component replacement and fault troubleshooting are more efficient, reducing operation and maintenance costs.
• The compact and beautiful appearance design saves on-site space occupation, and it can be flexibly deployed in narrow switch rooms.

4. The Trusted Choice of the Power System

From substations to large switch stations, the RF-391 Large-scale SF6 Recovery Unit has been widely used in various SF6 gas recovery scenarios. With the advantages of “complete functions, stable performance, and easy operation”, it continuously ensures the safe operation of equipment under complex working conditions, helps power enterprises reduce costs and increase efficiency, and realizes the compliant and efficient management of SF6 gas.

Choosing the RF-391 Large-scale SF6 Recovery Unit means choosing a “worry-free, efficient, and reliable” SF6 gas treatment solution!
