The handy devices allow filling of electrical equipment with SF6 gas directly from the bottle by overpressure. The primary gauge of the pressure reducer displays the bottle pressure in bar, the secondary gauge indicates the desired filling pressure to be set easily by means of the handle. The bottle pressure can be reduced to the desired filling pressure by the integrated pressure reducer.

With atmospheric test chambers it is not necessary to evacuate air before the test process. Test chambers of this construction type can be manufactured at significantly lower cost with a significantly larger volume than vacuum chambers.
We build these chambers with a chamber volume of up to 50 m as standard. This allows for reliable testing of even larger units and assemblies. However, we also recommend atmospheric testing when delicate, vacuum-sensitive components such as devices with touch screens need to be tested for their leak tightness.
This system configuration also allows the filling of the test objects with SF6 gas in the test chamber and subsequent recovery of the gas. However, with atmospheric pressure, the test duration is on average 10 - 30 times longer as the increase in concentration for atmospheric pressure is significantly lower.
This model range with a chamber volume of approx. 50 - 500 l is the ideal solution for testing smaller components where gas handling can take place outside the test chamber.
Vacuum testing of larger components (with or without integrated gas handling)We manufacture systems of this model range with a chamber volume of 500 l to approx. 20, 000 l. We recommend this model range where larger components need to be tested or where integrated gas handling in the test chamber is required. In this case, the test objects are filled with SF6 in the chamber.
Gradual evacuation and filling of the test objects is also possible in order to avoid an inadmissible differential pressure between the test object and chamber.
When testing SF6-filled control system components, SF6 can remain in the test object after testing. This makes the SF6 test method an interesting alternative to the known helium leak test in the field of GIS production as it is not necessary to recover the test gas from the test chamber after completion of the test process. As a consequence, the SF6 test method has a shorter handling time per test unit.
Mobile vacuum pump unit
Mobile vacuum pump unit with solenoid valve instead of ball valve
This version is equipped with a solenoid valve instead of a ball valve. Therefore, operating errors are avoided since the valve is closed automatically in case of function end or interruption of circuit.
The mobile vacuum pump unit is convincing by its easy handling. The unit serves for evacuation of air or nitrogen from switchgear. The 40 m/h vacuum pump enables a final vacuum of < 1 mbar. Thus it is guaranteed that no air / gas mixture is generated and the good insulation properties of SF6 are retained.
Steerable and fixing rollers allow comfortable transportation

Different performances are available (see options)
Adapters for other nominal widths are available
Protection of the vacuum pump against overpressure by a solenoid valve
