Just thinking out loud, not sure I'd do that but it's an idea!

depending on how hot in the rafters it gets, it could reheat your cooled air
other than that it could be mounted anywhere you want as long as everything slopes to a drain
on the drain, try to have a long leg under the cooler with a valve at the bottom
the leg is your daily reservoir to catch water

i run the coil copper above my compressor, air in on the top and gravity drain into the tank
i don't run a cooling loop in my home shop, 30 feet of headers drain back to the tank
it even drains back thru the regulator

the auto shop is a whole different animal...
5 to 8 shop employees all using air tools, paint booth, cnc plasma table and a 37 cfm compressor
our 60 foot initial cooling loop goes up high on a block wall and gravity drains into a refrigerated dryer
then back to the ceiling for distribution
we do use a desiccant dryer at the paint booth too
