RF-151 SF6 Recovery Unit

In the operation and maintenance of SF6 electrical equipment, vacuum pumping, recovery and storage, compliant refilling, and impurity filtration of gas are directly related to equipment safety and operational efficiency. Centered on “multi-functional integration + stable compliance”, the RF-151 SF6 Recovery Unit is tailor-made for gas handling in SF6 electrical equipment and switchgear chambers, providing a one-stop solution to address pain points of traditional decentralized handling such as low efficiency, cumbersome operation, and compliance difficulties.

Full-Function Integration for Greater Convenience and Efficiency

Breaking the limitation of single-function devices, this unit integrates five core functions in one system: vacuum pumping, SF6 gas recovery, equipment refilling, cylinder compression, and vaporized output:

• Visualized Vacuum Operation: The PLC intelligent interface monitors real-time vacuum level changes, offering clear visibility of operation and maintenance status to avoid blind operations.
• Flexible Recovery and Storage Options: Recovered SF6 gas can be stored in the unit’s on-board tank or connected external cylinders, adapting to different on-site storage needs.
• Multi-Adaptable Refilling Modes: Supports two modes – “direct refilling with pressure regulation” and “gas-phase/liquid-phase compression refilling”, accurately matching scenarios such as equipment pressure replenishment or cylinder filling.

Compliance-Compliant Design for Stability and Durability

Strictly adhering to the DL/T 662 industry standard, it ensures reliability in both structure and performance:

Excellent Protection and Maintenance: The semi-enclosed protective structure isolates external dust and moisture. The modular design eliminates the need for overall disassembly during maintenance, saving time and effort for daily upkeep.

Comprehensive Safety Details: Equipped with a vacuum pump anti-backflow valve to prevent gas backflow risks. The independent storage tank and gas heating system work in synergy to ensure stable gas flow in low-temperature environments and avoid efficiency impacts caused by condensation.

Efficient Purification + Rapid Operation for Visible Cost Reduction and Efficiency Improvement

Targeting core demands for SF6 gas purity and handling efficiency, the unit is equipped with multiple practical designs:

• In-Depth Purification Guarantee: The built-in high-precision filtration system removes moisture, decomposition products, and particulate impurities from the gas simultaneously, ensuring recovered and reused SF6 gas meets equipment application standards.
• Negative Pressure Recovery for Higher Efficiency: Innovative negative pressure recovery technology significantly improves gas recovery rate and reduces waste.
• Rapid Refilling to Save Time: The liquid SF6 refilling efficiency reaches “filling 50kg of liquid SF6 into a 40L cylinder in just 5-8 minutes”, far exceeding traditional devices and shortening equipment downtime for maintenance.

Global Adaptability for Unlimited Scenarios

Considering climate differences across regions, the unit offers optional cooling methods, enabling stable operation in both high-temperature and humid, or cold and dry environments. Currently widely used in various power systems – from substations to switch stations, and from regular working conditions to complex scenarios – the RF-151 SF6 Recovery Unit, with its compact and aesthetic design and user-friendly operation, serves as a reliable partner for SF6 gas handling, supporting safe, efficient, and long-term operation of power equipment.
