SF6 Gas Recovery Unit (GRU-4 PLUS)

ENERVAC’s latest SF6 Gas Recovery Unit incorporates a new and improved high pressure,totally oil-less compressor capable of 500 psi (34 bar) of pressure. This new technology allows for liquefaction of SF6 gas even in the warmer climates typical of the southern United States.The cart is ideally suited for servicing small volume SF6 equipment. All processes required for servicing SF6 equipment can be performed including gas removal, temporary storage, contaminant filtration to 0.1 micron, gas purification and drying, equipment evacuation and equipment re-pressurization. The cart is also ideally suited for consolidating partially-used SF6 bottles into one bottle.
