Counterflow and crossflow cooling towers use different airflow and water-flow arrangements, so the cooling tower fill design may also be different. In a counterflow cooling tower, water flows downward while air moves upward through the fill. In a crossflow cooling tower, air moves horizontally across the falling water. These different configurations affect the structure, dimensions and installation requirements of the cooling tower fill.

When selecting cooling tower fill, it is important to confirm whether the tower is a counterflow or crossflow design before ordering. Other factors, including fill dimensions, sheet spacing, water quality, operating temperature and existing support structure, should also be considered. We supply PVC cooling tower fill for both counterflow and crossflow applications and can review your existing fill specifications, drawings or dimensions to help determine a suitable replacement or new-project option.
