Service equipment Portable SF6 transfer unit Model GTU-10 WIKA data sheet SP 63.07 Applications ■■ Pumping SF6 gas out of equipment into gas cylinders ■■ Consolidating part-filled SF6 gas cylinders ■■ Filling of SF6 gas-insulated equipment Special features ■■ High compressor performance ■■ Compact dimensions ■■ Robust version for the service ■■ Clear display of the working pressure Portable SF6 transfer unit, model GTU-10 Description Portable service equipment series The model GTU-10 SF6 transfer unit is a module of the portable service equipment series. Modules of the series: ■■ Portable vacuum pump, model GVP-10 ■■ Portable SF6 filter unit, model GPF-10 ■■ Portable SF6 vacuum compressor, model GVC-10 ■■ Portable SF6 transfer unit, model GTU-10 ■■ Portable SF6 gas cylinder scale, model GWS-10 The compact dimensions of the model GTU-10 are ideal for mobile use. The fields of application range from the storage of SF6 gas in gas tanks to the filling of SF6 gas-insulated switches. During storage of the SF6 gas, the compressor can liquefy the gas in the storage vessel. Thus, the maximum storage capacity of a gas cylinder can be used. The connected storage vessels and supply lines must therefore be designed and approved for at least 50 bar pressure. The model GTU-10 is an instrument developed specifically for SF6 gas. Due to the selection of the oil-free running compressors, contamination of the SF6 gas by lubricant is eliminated.

Switching on again is only possible once the pressure at the output has dropped below 36 bar abs. After switching on the compressor, the SF6 gas is transported from the input to the output. With rising filling pressure, the SF6 gas is liquefied in the storage vessel with minimum space requirements. The compressor automatically switches off when reaching 40 bar abs., and the overpressure warning lamp illuminates. Depending on the selection of the output valve ( 10 = output not pressure-reduced, 9 = output pressure-reduced) the gas drawn in is pumped into the connected vessel via the output hose. The desired filling pressure can thus be set exactly at the built-in pressure reducer. 1 3 4 5 7 6 2 8 9 10 1 Overpressure warning lamp 2 On/Off switch 3 Pressure display, inlet pressure 4 Operating hours counter 5 Pressure reducer 6 Pressure display, output pressure reducer 7 Pressure display output pressure 8 Valve coupling, inlet, DN 8 9 Valve coupling, outlet pressure reducer, DN 8 10 Valve coupling, outlet, DN 8 Specifications Gas flow rate 1.1 m³/h Permissible inlet and outlet pressure ≤ 40 bar abs.
