Drift eliminators and the technology behind them continue to evolve as drift specifications grow more stringent and tower operators strive for the best performing products available to the marketplace. As such, the choice of best product for th application becomes more critical. One important aspect of drift performance is the pressure loss characteristic of a drift eliminator and the difference between dry and wet measurements. The differences between various eliminator configurations highlight the benefits of new technology and theory applied to drift eliminators to achieve the best performance and lower pressure drop. This yields continued improvements for the tower operator.
