The manufacturers care about SEER which is not directly tied to higher efficiency at high ambient temperatures.

But I would then think you would need to clean the coils monthly to be sure to eliminate any mineral buildup.
The company I represent makes a unit that has a fine mist. It also has a filter to remove the minerals to reduce deposits. Soon we will have a filter that will remove 99.9% of the minerals from the water. The system kicks on an off to conserve water. Savings in some areas run 25%-50%.
So far our company has not experienced the many of the problems listed.

the only answer i can give is based on experience and the answer is yes it does help, a little. i have done this before to get someone by but couldn't recommend it as a permanent fix.

Joe is exactly right about the mist. There is a patented flow control valve that has been out for many years now. Finally Carrier is using it on some of their products. It increases the efficiency of the evaporator coil up to 98%. You would think all the companies would jump all over that too, but they do not.
In fact some companies rather then really investigate it denigrate it because it was not invented by their company.
As you already know the evaporator coil can in many cases be very inefficient causing a huge loss of cooling capacity and increased energy cost.
So I do not believe these companies jump all over products that can help increase energy efficiency as you seem to think.
In many cases they probably have every reason to be skeptical since there has been a lot of scam products introduced.
I believe this to be a good product that can help because it is engineered correctly and has been tested extensively.
And the new filter coming soon will be a big improvement too.
I recommend this for those times the temps are far exceeding design parameters.
If you are in a stretch of 100+ degree days, and your system was designed for 90-95 degree days, the only thing anyone cares about is keeping the house cool.
(I have always wondered about the efficiency you could get if you put your condenser in a conditioned space)

I have a walk-in cooler and freezer with the condensers installed two floors down in a sub-basement. They work pretty well.

Everything you mention is true. With the proper filter and an extremely fine mist on the outside that is not directed at the coil works great. This reduces the problems to a minimum. The company spent several years testing and refining to make it work without problems. When the new filter is released that should completely stop any chance of mineral build up. This filter can be used for other applications too.
I am looking for other dealers in the US if anyone is interested.
Probably twenty - thirty years ago. I service many water cool condensers. I believed it was call "FRASER-JOHNSON". (not sure of the brand name). It worked pretty well, haven't seen them for over twenty years. Any old timer here remembered that?

Build you an air box sort of like a fan shroud on your car around your condenser coil, and run one inside cold air duct out to it, what little you might loose in air flow inside, you might make up in efficiency and savings outside.

Is there any data on this system showing the amount of water useage and estimate costs of water use along with actual savings and capacity gains. Then the cost of purchasing and installing this system along with it's maintenance?
I would think you'd find ther very little if any payback once you consider all associated costs. How much is you EER really going to improve, going for what 11 to 12? That not even a 10% energy savings. Even with $800 in cooling bills over a summer with a larger systtem, that's $80 per year. Lets say it's $100. Do you honestly think it will use less than evne $50 in water over thsoe months? There goes 1/2 your savings. How much does that filter cost? How long will it last. I bet it's almost $50 and will last 2 years. So now you've saved $25.... voided your equipemnt warranty and likely shortened it's life and for $25 you'll be out there once a week trying ot rinse off deposits and crap that builds up on it.
