(OP)
I would like to find information about Residential Condenser Evaporative Precoolers.
If you look at this link: http ://www.pge .com/003_s ave_energy /003c_edu_ train/pec/ info_resou rce/pdf/ac 2eval1.pdf
PG&E study shows a reasonable increase in efficiency.
But I can't find any information about any that are currently available.
Anybody know of some information?

This was before energy cost money, so I don't recall an efficiency gain number.

We never took real data as to performance gains, but they ran when it was 120 F on the roof.
Some guy in AZ built them for us but can't remember his name (I don't work for that company anymore). The pad was cellulose, it actually looked like the guy cut up cardboard boxes. A tstat would turn on a solenoid to admit water, and there was a needle valve for adjustment.
I am building a couple for my two home A/C units using PVC fill pads that come in 50' rolls.
YOu have to make sure the you have a WB temp of less than 80 or so, otherwise the drop in airflow due to the restriction does more harm than good.
