SF6 gas cart

Description of the SF6 gas cart Modular design of theSF6 gas cart series The GFU08 series of modular gas cylinder transport carts are used for the filling and refilling of SF6 gas in the required gas compartment. The modular design enables worldwide application through the various mechanical and electrical connections.The model range of the SF6 gas cart series is divided into 4 versions:Model GFU08-B: Filling cartModel GFU08-W: Filling cart with scalesModel GFU08-E: Filling cart with vacuum pumpModel GFU08-C: Filling cart with scales and vacuum pumpHigh-performance vacuum pumps Models GFU08-E and GFU08-C of the SF6 gas cart series are fitted with vacuum pumps. With these, the air is extracted from the SF6 gas compartments so that, afterwards, a professional filling can be made with SF6 gas. The basic version of the vacuum pump (model GVP-10) already has a suction throughput of 10 m³/h for fast pumping out, down to a final partial pressure of = 2.0 x 10-2 mbar [< 1.5 x 10-2 Torr]. For larger volumes, more powerful vacuum pumps are available, with a suction throughput of up to 44 m³/h. With 2-stage pumps, the final pressure can be reduced down to < 2.0 x 10-3 mbar [< 1.5 x 10-3 Torr]. The risk of either too high humidity or air concentration in the SF6 gas compartment is therefore not a consideration.High-accuracy scales High-accuracy scales determine exactly the filled SF6 gas volume. Thus, the SF6 gas cart model GFU08 is an ideal tool for using the mass-balance method in accordance with the IPCC directive for the preparation of emission reports. The flat design of the scales enables easy loading and unloading of the heavy gas cylinder by only one person.
