This device is suitable for electricl equipment production use, and also used at110KV～500KV GIS switchgear on-site installation and maintenance
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.
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.

In Purification Drying System,the effect of oil separation is not good. How to solve it?
The temperature of gas is likely to be high. To check whether the cooling fan runs normally and whether fan blades are in good condition. If the oil separator is broken, please replace it.
In Purification Drying System, the drying effect is not good. How to solve it?
It is possible that the molecular sieve saturation should be treated by self regeneration, or dry filter may be blocked. The system should be disassembled to replace inner parts if necessary.
