Hydrophilic Zeolite Coatings for Improved Heat Transfer: A Quantitative Analysis.

This article discusses findings of a study which examined the wetting diameter and lifetime of a water droplet on the surface of a bare, ZSM-5 coated and Zeolite-A coated stainless steel 304 substrate at different initial surface temperatures. Thin films are designed to reduce the pressure drop of the air that have been forced through the system, decreases the operation noise and the pumping cost. Metal corrosion is one factor to consider for a heat exchanger and several coatings are available as corrosion protection, including galvanized coatings and plasma vapor deposition (PVD) coatings.
