All Marley components are designed and selected to be part of an integrated system. For example, the spray pattern from nozzles and the pressure drop through drift eliminators both affect a fill’s heat transfer capacity. So, we include that impact in our thermal analysis. Drift eliminators must be effective at the air velocities where fill is most efficient. So, we’ve carefully designed both components to work together efficiently. How many other cooling tower companies can offer you this assura
