This cart is ideally suited for servicing smallvolume SF6 equipment. All processes required forservicing SF6 equipment can be performed withthis cart.The equipment is designed for the recovery, temporarystorage, conditioning, and dispensing of SF6 Gas. The equipment is designed for use in field service ofinsulated metal clad switchgear, bus ducts and individual circuit breakers.The AGRU-4 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 < 1.33 mbar.
- SF6 Gas cart down <0.67 mbar.
- Air and moisture from the switchgear< 0.67 mbar.
- Purify SF6 Gas by recirculating through the filter system:
- (D1) - Dryer Filter - Contains activated alumina to aid in the drying and purification of SF6 Gas.
- (P1) - Purification Filter - Contains Molecular Sieve 13X 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.
Weight of SF6: 29 lbs – 13 Kg
Features:
- Mounted of a convenient hand cart with 10” (250mm) pneumatic tires for ease of movement.
- Very easy to operate - only two valves to switchoperating modes
- High pressure, direct-drive oil-less compressor with 1000:1 compression ratio (capable of1000psi – 69 bar).
- Capable of liquid SF6 storage (50lbs.@60ºF /22.7 kgs.@15.5 ºC)
- Purifies, dries and filters to 0.1 microns duringrecovery and re-pressurization.
- Filters are easily changed without disconnecting any tubing or using any special tools.
- Auxiliary connection allows for infinitely expandable storage through use of external tanks.
- Comes complete with 9.8ft / 3m hoses and power cable.
- Colour change moisture indicator to monitor moisture in gas.
Applications:
- Recover and purify SF6.
- Evacuate air and moisture prior to filling.
- Consolidate SF6 cylinders.
- Store SF6 in liquid state in onboard storage orauxiliary bottles.
- Regulated filling of SF6 equipment.
- Purification of SF6 (removes particles,moisture, and SF6 decompositionproducts.
