Features & Benefits
Removes carbon dioxide from inert gases He, Ar, N
2
, H
2
, and clean dry air (CDA) to low ppb levels.
Functions by consuming carbon dioxide in a reaction with highly dispersed NaOH on a silicate support (reaction produces water that remains adsorbed in the purifier).
In highly critical applications, consider using an additional moisture trap after the CO
2
trap as a safety measure.
Note: Recommended for the inlet gas to have a moisture content of less than 10 ppmv (-60 °C dew point)
