What percentage of glycol do you use when you have outdoor air-cooled chillers?
(OP)
These chillers will be serving a 200 apartment hotel. The piping system is 4-pipe so I think they'll want to run it year round just in case someone is hot in their room but I'm not exactly sure if that's common or not. This is in Utah so it can get down to the negative temperatures now and then. All time lows can be -20 F although very uncommon. However, going 50% glycol seems kind of like a waste. Any insight on this is appreciated.

If the chiller would be off during the coldest days (which one could assume apartments) you cna afford the glycol to go slushy. If you need it to run on all days, like in a server room, you can't get it go slushy.

I've never seen a glycol system with chemical feeder. The fluid is for life (whose life?) Water systems have chemical feeders. You will want a glycol fillstation, though.
Also consider if you use PG or EG. For environmental reasons EG is on the way out (it seems).
