Product Details
Company Profile

　● Brief Description

　　LH4-20Y/18WG/400 SF6 gas recovery device is developed and researched independently by our company. It’s used for recovering and vacuumizing SF6 gas from insulated switchgear or filling SF6 gas into switchgear.

　　LH4-20Y/18WG/400 SF6 gas recovery device is designed with reasonable and compact construction and advanced technology according to Standard DL/Y622-2009.

　　● Main Features

　　1. This device has positive pressure and negative pressure recovery functions, with low residual voltage when recovering SF6 gas.

　　2. Vacuumizing adopts double-pole vortex sliding-vane rotary vacuum pump of joint brand, to accelerate the vacuumizing speed.

　　3. Purifying system adopted efficient separation dust-cleaning device, to dry and separate SF6 gas.

　　4. Gas storage tank with external plastic spraying and internal copper plating, equipped with liquid level meter, to guarantee the internal cleanliness.

　　5. Adopting intelligent heating and filling system to guarantee stable filling temperature.

　　6. Adopting electromotor control to guarantee the performance on the safe side.

　　7. Vacuum measuring instrument adopts the imported transducer to ensure high measuring precision.

　　8. This device is operated simply and reliably, with low noise, stable running, pleasing shape and compact construction.

　　9. The motor adopts automatic adjustment, which is safe and reliable.
