What is the purpose of drift eliminators in cooling towers?

• A. Minimize loss of water droplets to the environment.
• B. Increase water flow.
• C. Color water.
• D. Filter air.

Answer: (D)

Dr drift eliminators are all about cutting drift, the tiny water droplets that escape with the exhaust air from a cooling tower. They use surfaces or plates that cause droplets to collide and coalesce so they fall back into the tower instead of drifting out with the air. This directly reduces water loss to the environment and helps prevent moisture and chemical carryover. So, while you can think of drift eliminators as removing droplets from the exiting air, their main purpose is to minimize water drift, not to increase flow, color the water, or broadly “filter air.”
