▎Product Introduction :
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.
4.Self/external equipment vacuum pumping with real-time monitoring.
5.Negative pressure recovery for higher efficiency.
6.Vacuum pump anti-backflow valve.
7.Independent storage tank & gas heating system.
8.Liquid SF₆ filling (5~8 min for 50kg into 40L cylinder).
9.Optional cooling methods for global climate adaptability.
