A packing element (70,94,112) for an evaporative cooler, which comprises an apertured, corrosion resistant structure which includes a sheet of expanded metal. The metal is preferably of a ferritic corrosion resistant material such as 3Cr12. The invention also provides for a method of packing an evaporative cooler which includes using, in a single packing (68) for an evaporative cooler, packing elements (94) having a configuration suited to cross-flow conditions and, in addition, packing elements (70) having a configuration suited to counter-flow conditions. The invention provides further for a method of supporting a packing (68) having a trickle pack configuration, in a wet cooling tower (40). |
