DRIFT ELIMINATORS

REDUCE WATER LOSS AND EMISSIONS

In all different types of cooling towers drift eliminators are used to reduce the loss of water and emissions. Above the water distribution and the cooling fills, a layer of drift eliminators is installed for this purpose. It catches the water drops which are carried away with the air flow and redirects them into the cooling water circuit.

Drift Eliminators are available in two different types. The profile (TAP 160) is mostly used in bigger, the chamber types (TEP 130 and TEC 130) in smaller cooling towers

*These values base on the CTI ATC-140 test method (Isokinetic Drift Test Code) and are to be understood as guideline values only. The performance of the drift eliminator is indicated by the ratio drift loss/water flow rate (in % of the circulating water volume). These guideline values base on measurements with a rain density of 20 m³/m²h and an approximate medium air velocity of 3 m/s. To achieve these values, an absolutely tight assembly of drift eliminator elements to each other, to the housing wall and to any openings is required. The face velocity must not be exceeded at any point of the drift eliminator.
