Does anyone know of a good web-available white paper on the causes of
aluminum fin corrosion on commercial air conditioning condensing
Not coastal location related; units are in central Florida.

I see things haven't changed here. I ask a legitimate question and
"Waste my time once, shame on you. Waste my time twice, shame on me."
It is a case of disimilar metals and on the coast with electrolyte
like salt the fins rot away. There are other electrolytes besides salt
so maybe take a look at what kind of industry is up wind.
Now other causes I have seen, and this happened on a copper tube -
copper fin coil was from electromagetism, roof top units and their
close proximity to mutilple overhead power services.
If the units are on the ground then it is also the case of good old
fashioned dog piss
