Drift (or windage) is the term for water droplets of the process flow allowed to escape in the
cooling tower discharge. Drift eliminators are us ed in order to hold drift rates typically to
0.001%-0.005% of the circulating flow rate. A typical drift eliminator provides multiple
directional changes of airflow while preventing the escape of water droplets. A
well-designed and well-fitted drift eliminator can greatly reduce water loss and potential fo r
Legionella or other chemical exposure.
