Abstract
Heat transfer surfaces in condensing heat exchangers are often coated with a hydrophilic coating to provide wetting and wicking. This coating is typically porous and continuously moist during operation and, therefore, a potential breeding ground for microbes. The inclusion of an antimicrobial agent, such as silver oxide, in the coating inhibits microbial growth and improves adhesion to the heat transfer surfaces.
