Drift Eliminators

Drift eliminators


Drift eliminators are used to capture water droplets in the air stream that otherwise would be lost to the atmosphere. Entrapping these droplets is important for not only conserving water as a resource but also to prevent cooling tower water from contaminating the area peripheral to the cooling tower.

The cooling tower industry uses drift rate to compare drift eliminator performance, a relationship that correlates droplet capture efficiency to the water circulation rate in a tower.

COOLDECK’s drift eliminators are specifically designed to achieve maximum drift removal efficiency in both crossflow and counterflow tower applications with various product options available to minimize pressure drop, drift loss, cost, or a combination of all three.

Our Product Range


Cellular Drift eliminators

CD-S130/146, made out of rigid PVC, is designed to remove maximum entrained drift particles from air stream efficiently, with minimum pressure drop, thereby reducing the fan power requirement

CD-100 Drift Eliminators

The CD-100 drift eliminator is a blade (profile) type drift eliminator designed for optimal drift entrapment efficiency, very low pressure drop and excellent economies.


CD-146 Drift Eliminators

The CD-146 drift eliminator is a blade (profile) type drift eliminator designed for optimal drift entrapment efficiency, very low pressure drop and excellent economies.

Double Wall Drift Eliminators

The DrifEl146 drift eliminator provides dimensional stability and durability, with rugged design & structural integrity for long service usage.
