ABSTRACT:
A preformed non-ferrous shield which will fit against but stand off of the interior side walls of the wet section of a single inlet evaporative cooler. It has molded in air access channels in one side. These air access channels permit the differential in air pressure between the inside and outside of the cooler cabinet, when the cooler is in operation, to actively draw a flow of dry air into and between the shield and the cooler's wet section interior side walls thereby retarding all forms of corrosion but specifically retarding anaerobic corrosion, oxidation of a ferrous material caused by the absence of free oxygen molecules. The shield is formed of a thin, flexible, impermeable material which forms a barrier that provides for a convenient structure for blocking water from flowing onto the interior side walls of the cooler's wet section during operation and provides for the immediate evaporation of remaining moisture caused by sweating after the cooler is turned off. The shield facilitates cleaning, repair and installation of single inlet pads and greatly reduces the opportunity for corrosion to the cooler.
