    Product Description

    SF6 gas recovery purification and refilling device is used to vacuum various electrical equipments, refilling electrical equipment with SF6 gas, and recover SF6 gas from the used or tested electrical appliances, purify, compress and store it in the storage tank.

    The recovery unit is suitable for SF6 electrical appliances and GIS combined electrical appliances.

     

    The device is composed of recovery system, refilling system, vacuum system, purification system, gas storage system according to the standard of DL/T662-1999 "sulfur hexafluoride refilling and recovery device". The device has the following main applications:

    • Vacuuming and vacuum measurement of the device and electrical equipment;
    • Recover gas in electrical equipment;
    • Dry and purify the SF6 gas for recovery and refilling;
    • Refilling for SF6 electrical appliances;
    • Compress, store, and bottle the SF6 gas in the electrical appliances.

     

    Features

    • Advanced design, complete functions, reasonable structure, simple and clear operation.
    • Compression system: SF6 compressor, no leakage.
    • The vacuum pumping system adopts a two-stage rotary vane vacuum pump, and an automatic oil return prevention device is provided in the system.
    • The purification system uses CKD company’s principle filter. The filter uses electric heating and built-in high-efficiency adsorbent. The purification effect is more significant (no need to replace adsorbents frequently).
    • The three-phase power supply of the device's electrical system is automatically confirmed and automatically protected from phase failure.
    • The SF6 special valve with the latest technology in the device control system.
    • The storage system is configured according to the user's requirements.
    • The equipment adopts mobile type, PLC automatic control, one-button operation.
