Abstract
A heat exchanger coil has its fins coated with a photocatalytic semi-conductor material in such a manner that its fins may then be illuminated by UV light to activate the material so as to cause the oxidation of organic pollutants which are on the fin coils themselves or in the air passing therethrough. A preferred photocatalytic semi-conductor material is titanium dioxide, which may be applied to the fin stock prior to the fabrication of the coil.
