This treatment is applied via spray and covers the exterior of the heat exchanger with a layer of polyester paint.
This treatment is applied to the heat exchanger through an electrophoretic process (immersion in a liquid bath of epoxy paint and application of an electrical charge) and ensures a uniform and controlled paint thickness even in the depths of the fin pack, where powder coating would struggle to reach.
This coating on the aluminum coil coating can be used as protection from corrosion in all heat exchangers.
It acts by making the surface less hydrophilic, thereby reducing the contact surface and the dwell time of water droplets, which also decreases the likelihood that pollutants present in them remain in contact with the fin.
This aluminum strip coating can be utilized in evaporative and cooling heat exchangers with the aim of achieving a film condensation of water vapor on the fin surfaces.
With such treatment, the fins are rendered hydrophilic, thereby becoming more water-affine and avoiding the formation of water droplets.
