This device is suitable for electricl equipment production use, and also used at 110 kv ~ 220 kv 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.

The low pressure of refrigeration compressor is too low. How to solve it?
Causes and solutions: the expansion valve is blocked and the solution is to clean it or clean the dry filter; the cooling system leaks and source of leakage should be found and fixed.
