AIR

A TOTAL SOLUTION FOR AIR SEPARATION UNIT GASES

In the ASU process, ambient air is filtered and compressed to remove dust. The air is then cooled and purified through a series of filters to remove most of the carbon dioxide, hydrocarbons and moisture. Moisture measurements are made after the compression and purification steps. The moisture transmitter range recommended for ASU applications is 0-100ppm.
