Gas refilling and evacuating devices

For reliable refilling of SF6 gas by overpressure

SF6 gas refilling device

Portable with rubber hose and coupling DN8 and DN20
Portable in a case with rubber hose and couplings DN8 and DN20

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.

Other features:

  • Self-closing couplings for emission-free gas handling
  • Available as accessories for the world’s most commonly used bottle connections

Evacuating and refilling device

In practice, the device covers two important functions. The integrated vacuum pump is the core component of the device. This vacuum pump evacuates the air down to < 1 mbar so that no air/gas mixture is produced during the subsequent filling process. The well proven DILO coupling principle ensures safe handling without emission.

Using the 3-001-4-R022 version the filling weight can be registered comfortably by means of a weighing scale. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a certain time. Thanks to the tare function high precision quantification of gas inputs and outputs is possible.
