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.
