RF-051 Compact SF₆ Recovery Unit

The RF-051 Compact SF₆ Recovery Unit is designed for comprehensive gas handling services in SF₆ electrical equipment and switchgear chambers. This integrated system combines multiple functions including vacuum pumping, gas recovery, refilling, cylinder compression, and vaporized output. During vacuum operations, the PLC interface displays real-time vacuum level changes. Recovered gas can be stored in onboard tanks or external cylinders, while refilling offers multiple options: direct filling (with pressure-regulated output) or compression filling (gas-phase or liquid-phase compression).

Engineered to meet DL/T 662 standards, the unit features a semi-enclosed protective structure with modular design, ensuring complete functionality, stable performance, easy maintenance, user-friendly operation, and an aesthetically compact form factor. Ideal for diverse SF₆ gas recovery scenarios, it is widely deployed across power systems for reliable operation under varying conditions.

▎Key Features ：

1.SF₆ gas recovery and storage.

2.Refilling stored SF₆ to switchgear or pressure vessels.

3.Filters moisture/decomposition products/particulates from SF₆.
