In counterflow cooling towers, the air and water flows are positioned opposite one another, which results in the maximum area of dissipation being achieved. The air flowing in travels vertically over the splash fill, while water is sprayed from the distribution system above. This spraying method makes the cooling towers more freeze-resistant than crossflow cooling towers, in addition to improving heat transfer. Counterflow air cooling systems are typically smaller and more efficient than crossflow air cooling systems, but they still require cooling tower maintenance, as provided by Hamon, a counterflow specialist.
