Water system component

Disclosed herein is a hydrophilic coating that includes an adhesive agent; an insolubilizer for insolubilizing the adhesive agent; titanium dioxide; and a metal oxide selected from the group consisting of silver oxide, copper oxide, iron oxide, magnesium oxide, and combinations thereof. The hydrophilic coating is useful on the heat transfer surfaces of a condensing heat exchanger.

Antifungal/antibacterial hydrophilic coating

A hydrophilic coating system may comprise a second coating disposed on a condensing surface, the second coating comprising a second adhesive agent, a second insolubilizer, a second inorganic compound, and a second antimicrobial agent. The second coating may comprise between 40% and 50% by weight second adhesive agent, between 12% and 16% by weight second insolubilizer, between 30% and 40% by weight second inorganic compound, and between 3% and 4% by weight second antimicrobial agent.
