▎Product Introduction ：
The RF-300N is an intelligent PLC-controlled SF₆ gas recovery system developed for comprehensive gas handling services including vacuum pumping, gas recovery, refilling, cylinder pressurization and gas purification in SF₆ electrical equipment. This integrated system combines multiple functions with real-time PLC monitoring, featuring modular design with compact structure and user-friendly operation. The equipment complies with DL/T 662 standards and is widely applicable in power, metallurgy and petrochemical industries.
▎Key Features ：
1.SF₆ recovery/purification/storage meeting GB/T 12022 standards.
2.Refilling purified SF₆ to switchgear or pressure vessels.
3.Filtering moisture/decomposition products/particulates from SF₆.
4.Self/external equipment vacuum pumping with real-time monitoring.
5.Elevatable distillation tower for enhanced purification.
6.Negative pressure recovery for higher efficiency.
7.Anti-backflow valve in vacuum pump.
8.Independent distillation tank & gas heating system.
9.Liquid SF₆ filling (5-8 min for 50kg into 40L cylinder).
10.Industrial touchscreen control.
11.Optional embedded analyzers for SF₆ purity/humidity/contaminants.
