• Final oxygen below 10 ppb
  • Carbonation of deaerated water
  • No vacuum required
  • Low CO2 / N2 consumption

The deaeration column is filled with high-efficiency structured packing. Its large internal surface ensures a maximal contact area between gas and liquid. Water is homogeneously distributed on the top and CO2 / N2 is injected at the bottom of the column. While the water flows downwards through the packing, the CO2 / N2 rises counter-currently, removing the oxygen to concentrations as low as 10 ppb. A drive controlled pump maintains the level in the column and forwards the deaerated water into a buffer tank or point of use.

The unit has an uncompromising sanitary design and is fully CIP cleanable.
