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.

Functionality
The compressor is connected to the input and output sides
with appropriate fittings and hoses.
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.
