Our institute produces and sells SF6 gas recovery device, SF6 vacuumizing-charging device, SF6 gas leak detector (quantitative & qualitative), and SF6 gas moisture meter (quantitative & qualitative)
SF6 Gas Recovery-Charging Device.
SF6 (Sulfur hexafluoride) Gas Recovery-Charging Device is the device used for recovery and disposal of SF6 gas when manufacturing, installing and maintaining SF6 electrical equipment.
Referring to JB/DQ2588-90 “SF6 Charging and Recovery Device” drafted by Ministry of Machinery and Electronics Industry, and world famous brand products, we self researched, developed and manufactured the SF6 Gas Recovery-Charging Device, which except the general functions such as vacuumizing, charging, recovery and storage, our addition, it SF6 Gas Recovery-Charging Device is possessed the following features:
1.
Adopting international advanced design principle of freezing liquefaction reduces working pressure of the system and greatly improves working efficiency of recovery.
2.
Adopting column liquid level indicator, liquid level indication of SF6 is visual and accurate.
3.
Equipped with digital display vacuum gauge.
4.
Equipped with self-renewable dry filter.
5.
Fill SF6 gas into steel cylinder.
6.
Flow chart is drawn on operation panel, and it is easy to operate.
7.
Adopting wind cooling, moveable mode, it can be used without water source.
