Liquid SF6 storage with an oil-less compressor up to 34 bar
AGRU-4
SF6 gas handling equipment
AGRU-4
SF6 gas recovery unit
Recovery, purification, storage and refilling of SF6 in small-volume equipment.
All SF6 servicing on two wheels
The AGRU-4 recovers, temporarily stores, conditions and returns the SF6 of small-volume equipment: metal- cart with 250 mm tires, it changes operating mode with just two valves and also consolidates partially used SF6 bottles into a single cylinder.
Liquefaction in any climate
The high-pressure, oil-less compressor with a 1000:1 compression ratio reaches 34 bar and liquefies the gas even in warm climates. The recovered SF6 is stored in the on-board 22.7 kg tank, and an auxiliary connection extends storage to external cylinders without limit.
Main features
- Purifies, dries and filters to 0.1 µm during recovery and refilling.
- Filters replaced without disconnecting tubing or special tools.
- Colour-change moisture indicator monitors the gas at a glance.
- Stainless steel fittings for corrosion resistance and durability.
- Recovery down to 100 mbar; optional XDS vacuum stage below 1 mbar.
- Comes complete with power cable.
Applications and options
Applications
- Recovery and purification of SF6 in switchgear and circuit breakers.
- Evacuation of air and moisture before filling.
- Consolidation of partially used SF6 cylinders.
- Liquid SF6 storage on board or in external cylinders.
- Regulated refilling of SF6 equipment.
Options
The unit accepts a storage tank heater and an insulating blanket for cold sites, 3 m or 6 m hoses in rubber or stainless braid, and an optional vacuum compressor of 3.3 m³/h that takes SF6 recovery to 99.9 %.
