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 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.

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.
