In the SF6 gas handling operations of the power system, the RF-391 type SF6 large-scale recycling device has become the preferred equipment in the industry due to its integrated functions and core technical advantages. This device not only meets the DL/T 662 standard, but also solves pain points such as low purity and insufficient recovery rate in gas handling through its efficient filtration system and negative pressure recovery technology, and is widely applicable to various maintenance scenarios of SF6 electrical equipment.

Core Functions: One-stop SF6 Gas Handling Solution

The RF-391 type SF6 large-scale recycling device integrates functions such as vacuum pumping, gas recovery, refilling, cylinder pressure filling, and vaporization output, enabling highly efficient operations throughout the process:

Vacuum Pumping Phase: The PLC operation screen displays real-time changes in vacuum degree, accurately controlling the vacuum state of the equipment and external containers, laying the foundation for subsequent gas handling.

Gas Recovery: It can flexibly recover SF6 gas to the built-in gas storage tank or external cylinders. Coupled with the negative pressure recovery technology, the gas recovery rate is significantly increased.

Diversified Refilling Modes: It supports direct filling (including pressure-regulating output) and pressure filling (gas/liquid pressure filling), adapting to the gas replenishment needs of different equipment.

Technical Advantages: Key Designs Ensuring High Efficiency and Safety

Efficient Filtration System

The RF-391 type SF6 large-scale recycling device can deeply filter moisture, decomposition products, and solid particles in the gas, ensuring the purity of the treated SF6 gas and extending the service life of electrical equipment.

Negative Pressure Recovery and Anti-backflow Oil Design

The negative pressure recovery function is the core to improve the recovery rate. Coupled with the anti-backflow oil valve of the vacuum pump, it not only reduces gas waste but also avoids oil backflow from contaminating the equipment, providing double protection for operational safety.

Rapid Refilling and Filling Capacity

The independent storage tank is equipped with a gas heating system, greatly shortening the refilling time. The liquid filling efficiency is also industry-leading - it can fill a 40L cylinder with 50kg of SF6 in 5 - 8 minutes, meeting emergency replenishment needs.

Global Environmental Adaptability

It can be equipped with different refrigeration methods. Whether in high-temperature or cold regions, it can maintain a stable recovery efficiency, ensuring reliable operation in various power scenarios worldwide.

Application Scenarios and Core Value

The RF-391 type SF6 large-scale recycling device features a semi-closed protective structure and modular design, taking into account both operational convenience and maintenance flexibility. Its application in the power system not only reduces the cost of SF6 gas loss, but also reduces equipment downtime by improving processing efficiency, providing strong support for the maintenance of SF6 electrical equipment in substations, power plants, and other places.

Choose the RF-391 type SF6 large-scale recycling device. With its core technologies such as efficient filtration and negative pressure recovery, make the SF6 gas handling operations in the power system more efficient, more economical, and more reliable.
