Low pumping head, thus lower operational cost.
+ Accepts variations in water flow without changing the distribution system
+ Easy maintenance access to vital parts.
+ Reduced drift loss due to the absence of water droplets.
+ Lower in noise due to absence of water noise.
‐ Larger foot print of the tower.
‐ Large air inlet surface makes icing difficult to control.
‐ Tendency of uneven air distribution through the infill due to the large inlet surface
The air distribution systems for counter flow and crossflow towers have advantages and disadvantages inherent in their
