Keep in mind…

Drift for towers with three-pass high efficiency eliminators constitute a small percentage of water usage.

Unlike thermal performance, drift rates are not certified and field drift tests are cost prohibitive for most applications.

Drift rates below 0.001 are difficult to measure in the field.

Certain water treatment chemicals can impact the drift rate.
