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.

Other features:

  • Stable frame
  • Accuracy of the weighing scales ±20 g (±50 g only for 3-001-4-R122), 10 g increments
  • Integrated serial interface for data exchange or monitoring
  • No emissions by self-closing couplings
  • Available as accessories for the world‘s most commonly used bottle connections
  • Hose reel
  • Couplings can be exchanged without any gas loss
  • Primary gauge NG63, class 1.6 / Secondary gauge NG100, class 1.0
