We developed the AGRU-8 for our customers whofound they needed more storage and recoverycapacity than smaller handcart mounted units, the AGRU-8 is available without the bulk andhigh price of a large skid or trailer mounted unit. The equipment is designed for use in field service ofinsulated metal clad switchgear, bus ducts and individual circuit breakers.The AGRU-8 SF6 Gas Servicing Cart shall be fully assembled on a two-wheeled heavy-duty handcart,which shall be sufficiently braced to minimize vibration. Handcart will be complete with lifting eye, hosehook and power cable storage.
Funtions:
- Recover, purify and store SF6 Gas from the switchgear to the storage tank.
- Evacuation:
- Service hoses < 0.5 mbar
- SF6 Gas cart down <0.5 mbar
- Air and moisture from the switchgear< 0.5 mbar
- Purify SF6 Gas by recirculating through the filter system:
- (D1) & (D2)- Dryer Filter - Contains activated alumina to aid in the drying and purification of SF6 Gas.
- (P1) - Purification Filter - Contains Molecular Sieve 5X to remove arcing by-products.
- (F1) - Particulate Filter - Will filter all particulate matter down to 0.1 micron nominal.
- Pressure regulated recharging of SF6 Gas to the switchgear from the storage tank.
- Evacuate SF6 Gas from the cart to an external storage tank for maintenance purposes.
Features:
Applications:
GIS
- Mounted of a convenient hand cart with 10” (400mm) pneumatic tires for ease of movement in gravel switchyard enviroments.
