Reverse osmosis water is the best without any minerals in it. Bottled water like Aquafina or something like it is fine. If needed you could use an additive like purple ice.
Heck yeah I use tap water. No way I'm paying for water just to cool my compressor.
Tap water varies quite a bit between localities. You should probably use imported mineral water with a quart of Russian Vodka to act as antifreeze. And you should probably throw out the entire batch after every use. Actually, tap water should be fine. As long as you drain out the system between uses, you won't grow bio film in the system. The running temperature would also help kill organisms. No additives necessary. If it will run on Chinese tap water, ours should be fine.
I'm lucky that I have a whole house water softener system, so that helps with the calcium deposit.I'm thinking that adding CLR to the water would help with mineral deposits.
I use tap water also. I did the purple ice thing the first time and quite honestly, don’t see a difference this time without it. In fact, when I had the purple ice added to the water, it developed a slimy film that lined everything in the tank. I dumped it, flushed the lines, cleaned the tank and pump and am using straight tap water now with no issues and no slime!

Also, if there's any iron in the system(and I hope there isn't), you'll get more rust running with a low pH(acidic) than with a higher one.
Looks like very few options to keeping the cooling system free from acuminating minerals in a compressor.

I would actually do this while the compressor is not in use of course, perhaps just a few times a year

Distilled water - has no minerals in it to make deposits.
