The VF19 PLUS is for use in counterflow cooling towers where water quality is poor (poor make-up water or process contamination). Typical applications are power, refining, chemical, mining, and food processing.
Because cooling tower spray systems create a washing effect that reduces the fouling potential of the top 12 inches (300 mm) of fill, a top layer of OF21MA or CF1900 should be considered to improve overall performance.
