20-19: Impact of Water Surface Tension on Drift Eliminators

Over the recent years, an increased number of cases were reported to CTI in which abnormal levels of drift were found. The reports come from various sources: end users, CTI testers, cooling tower manufacturers or suppliers of drift eliminators. They all describe a high level of drift despite a correct installation of the product. While the number of cases remains marginal (~2 per year), it is necessary to understand their origins.
