Efficient cooling tower performance relies on more than water distribution and heat transfer. Air quality, water conservation, and environmental stewardship are equally critical. A cooling tower drift eliminator—also known as a cooling tower mist eliminator—is a key component designed to prevent fine water droplets from escaping into the atmosphere. This control minimizes water loss, protects surrounding equipment, and ensures compliance with environmental regulations.
Without proper drift control, entrained droplets can carry treatment chemicals, biological matter, or contaminants beyond the tower, potentially impacting nearby structures and ecosystems. By integrating high-efficiency drift eliminators, operators can maintain optimal cooling tower performance while supporting sustainable and compliant operations.
Understanding the Function of a Cooling Tower Drift Eliminator
A cooling tower drift eliminator functions by forcing moisture-laden air to change direction several times as it exits the tower. Through this process, entrained droplets coalesce and drain back into the cooling system rather than being released into the environment.
The design of a drift eliminator directly influences drift loss, pressure drop, and maintenance frequency, all of which affect the tower’s overall efficiency.
Key Performance Goals of Drift Eliminator Design
Effective eliminator design aims to:
- Reduce drift loss
- Maintain a low pressure drop to support efficient airflow
- Ensure mechanical strength under high-velocity, high-humidity conditions

Cellular Drift Eliminators: Design and Functionality
Cellular Drift eliminators feature a honeycomb or block arrangement of curved channels that create multiple directional air changes. As moist air passes through, droplets are captured and drained efficiently.
This design achieves high collection efficiency with minimal pressure loss, making it ideal for large industrial or power plant cooling towers requiring superior drift control and compact form factors.

Vane-Type Drift Eliminators: Design and Functionality
Vane-type drift eliminators use parallel blades with precisely contoured surfaces that guide airflow while separating entrained droplets. Each vane intercepts moisture, allowing water to return to the cooling system.
Their robust, open structure offers ease of cleaning, low fouling potential, and consistent performance in demanding cooling environments with elevated temperatures or humidity.
Cellular vs. Vane Drift Eliminators: A Technical Comparison
While both designs perform well, cellular eliminators typically offer higher droplet capture efficiency with lower resistance, ideal for systems prioritizing aerodynamic efficiency.
Vane-type designs, on the other hand, provide structural durability and simplified maintenance—an advantage for facilities where accessibility and reliability are paramount.
Selection ultimately depends on tower configuration, air velocity, water quality, and operating conditions.
