Condensation and corrosion can be major problems when surfaces are exposed to environmental conditions. Because of geometry it may be difficult to drain condensate, leading to increased corrosion or frosting at lower temperatures. Superhydrophobic (SH) materials can minimize anti-condensation and corrosion. SH coatings can be tailored for micro-channel heat exchangers, fin tube coils, and internally enhanced shell-tube heat exchangers. The impact of SH coatings on heat transfer performance needs to be considered along with the overall energy efficiency improvement resulting from SH coatings. SH coatings can help reduce performance degradation from corrosion by 50% and therefore improve the operational efficiency.
