In a crossflow cooling tower, air moves horizontally across falling water. In a counterflow cooling tower, air moves upward while water flows downward. These different airflow patterns require different fill layouts.
Crossflow fill is often designed for hanging or bonded installation. Counterflow fill is commonly assembled into vertical packs with specified sheet spacing and pack height.
When selecting replacement fill, match the tower design first, then verify the sheet profile, dimensions, spacing, water loading and support method.
