MARLEY MX75â€™s design uses integrally molded louvers and drift eliminators. The louvers ensure precise air distribution, prevent water from escaping, and guarantees virtually ice-free operation even in extremely cold weather. The drift eliminators typically reduce drift emissions from the tower by a factor of ten or more. Drift eliminators are designed to discharge air directly toward the fan, virtually eliminating drift spotting on adjacent buildings and property. Less drift means you save on your water bills and water treatment chemical expenses.
