SF6 gas evacuating and refilling device 3-001-4-R122 series

cylinder cartmobilewith electronic weighing scale

Mobile as cylinder cart with wire-braided hoses • vacuum pump for evacuation of air (16 m/h (at 50 Hz); 19m/h [at 60 Hz)), final vacuum 1 mbar • pressure reducer for SF6 • SF6 cylinder connection W 21.8 x 1/14" • gauge 0 to -1,200 mbar • primary gauge NG63, class 1.6, 0 - 60 bar • secondary gauge NG100, class 1.0, 0 - 10 bar • indication units in bar, ps, kPa • ball valve DN8 with hand wheel • DILO couplings DN8 and DN20 • two 6 m long wire-braided hoses DN8 • ditigal weighing scales for SF6 cylinders, 0 - 150 kg with tare function, accuracy ÷ 0.02 % • 3 m long electrical connecting cable • solid tyre wheels • paint: anthracite-orange For evacuation of air and safe refilling of SF6 into gas compartments by overpressure This device covers two important functions: The integrated vacuum pump allows the evacuation of air down to < 1 mbar so that no air/gas mixture is produced during the subsequent filling process. The use of gastight and selfclosing DILO couplings guarantees emission-free gas handling. The weight of the gas to be refilled can be conveniently registered (with the 3-001-4-R022 / R122 version) by means of the integrated weighing scales. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a longer period of time. Thanks to the tare function, the gas can be precisely quantified. Advantages & functions • frame • hose reel • integrated serial interface for data exchange and monitoring • couplings can be exchanged without any gas loss • digital display with internal battery (IP65) • weight indication reversible from kg to lb • most common global cylinder connections available as accessories
