Description

Oxygen in beer or soft drinks affects the preservability and the taste. Therefore, it is important to use an optimally deaerated water for the production of soft drinks and the redilution of beer. GEA offers a 2-stage water deaerating system which achieves an excellent value of residual oxygen and is thus especially suitable for these and some further applications.

Special Features:

  • Low residual oxygen content
  • Low operating expenses
  • Low CO2 consumption
  • No sealing water consumption
  • Assembled ready to work, i.e. low assembly costs
  • Deliverable for wide range of flow rates
  • Option: Control of the residual oxygen


In the first stage (B1) the largest part of oxygen is extracted by pure vacuum deaeration. Being mixed with CO2, the predeaerated water is carried into the second stage (B2). CO2 increases the release of oxygen. The CO2-oxygen mixture is also sucked off by the aid of the vacuum pump via tank B1 in the reverse flow direction of the spray jet, thus increasing the deaerating effect of the first stage. By a discharge pump (P2) the deaerated water is carried to the consumer. The vacuum is generated by means of a dry-running rotary piston pump. The operating expenses are considerably reduced due to the fact that no sealing water is required. Detectors for pressure (PIA), level (LA), and possibly oxygen (QIA) monitor the system for its proper function.

The system is cleaned via the product path. In addition, an optimum cleaning effect is obtained by the spray balls in the deaerating tanks.
