Cross Flow vs. Counter Flow Cooling Tower (The Main Alternative)
This is the most important comparison. The other common design is the Counter Flow Cooling Tower.
| Feature | Cross Flow Cooling Tower | Counter Flow Cooling Tower |
| Flow Direction | Air flows horizontally, water falls vertically. | Air flows vertically upward, water falls vertically downward. |
| Water Distribution | Uses a gravity-fed open distribution basin at the top. | Uses a pressurized pipe and spray nozzle system within the tower. |
| Air Inlet | Large, open sides along the entire height of the fill. | Located at the bottom of the tower, around the entire perimeter. |
| Pressure Drop | Generally has a lower air-side pressure drop, which can mean lower fan horsepower and energy consumption. | Typically has a higher air-side pressure drop due to the more restrictive path. |
| Footprint | Has a larger footprint (area it occupies) for the same capacity. | Has a smaller footprint but is often taller. |
| Freeze Protection | In cold climates, the exposed water distribution on the sides can be more susceptible to freezing. | Generally better for cold climates as the water distribution is internal. |
| Maintenance | The open distribution basin is easily accessible for inspection and cleaning from the top. | Nozzles can be more prone to clogging and are harder to access for service. |
