Principle
The air flows horizontally and the water falling downwards meets the air at different temperatures. Therefore the heat transfer is not always optimized.

Area
The area required is larger due to its constructional features like larger plenum chamber. Also the arrangement and material of the pack is different and requires a higher area.

Air Flow
Since the air-water contact time is lesser, more air is required to effect heat transfer.

Distribution System
The distribution is done through open trough systems on the fan deck, fitted with nozzles. Distribution may not be as uniform as the counter flow type and is easily attacked by algae, causing problems like scaling and clogging of openings.

Recirculation
Since the air intake area extends from the bottom to the deck level, the flume discharge is very close to the air intake area at the top. This creates the effect of recirculation wherein the discharged air re-enters the tower through the air intake at the top. This creates a significant reduction in performance.

Fill Pack
Only splash type fill used in cross flow cooling towers. Usually splash fill will be V bar or timber laths.

Power Consumption & Pumping Head
The fan power consumption is higher as the airflow required is higher. The pumping head is also higher since the distribution is located at the fan deck level.

Maintenance
Maintenance for cross flow towers is time consuming and usually requires more skilled technicians on the job as the movement of material is more difficult.
