The drift eliminator is one of the cooling tower parts that is used to minimize the amount of process water loss within the cooling tower for resource usage efficiency as well as keeping an eye on the environmental concerns.
Here at Linquip, we have established a strong platform for the suppliers of cooling tower parts and products for the convenience of clients in their procurement process and management.
In what follows, some brief explanation regarding the types, manufacturing, and replacement of drift eliminators is presented.
What Is a Drift Eliminator

A by-product of intimate contact between water and air in the fill is the water droplets that have the same
composition and quality of the circulating water flowing through the tower. These (solid) droplets are called 'drift', and they are different from the pure water vapor in the effluent air stream or solid droplets formed by the condensation of that vapor.
The composition of this process water droplets or drift is hazardous for the environment. Moreover, it is not desirable for the system to lose its process water circulating in it. Therefore, a drift eliminator, which is an ensemble of passageways the airstream moves through to leave the tower, is used to prevent the drift from escaping the tower.
