<p>A gas/liquid contact media for use in an evaporative cooler has a fibrous material structure (Fig.3, item 13) impregnated with a polymer-based continous phase designed to have solubility and interfacial tension properties that promote intimate wetting with in-service water while inhibiting scale deposition, and an overall cationic charge on the polymer to repel positively charged particles or ions in the water in order to further prevent scale build-up on the media.</p> |
