I live in DRY XXTREME SW Utah.

I have two 20' x 8' containers. Inbetween them is 16' of space. I am
enclosing the ends of the space with covered gates, and putting a roof on
the whole 1320 sf.

I want to put evaporative coolers in there. I see them that are stationary,
and pull outside air and blow it inside. I also see roll around evaporative
coolers.

Which one works better? It seems that pulling 105 degree air from the
outside and cooling it would only give so much of a temperature drop.
Pulling inside air, say 85 degree and cooling it might work better. BUT,
the inside air would be humidified somewhat, and I don't know if the
evaporative effect would be as great.

Plus, the roll arounds seem to have to be filled manually, although I could
use a hose, but that would be just another trip hazard on the floor.
Stationary ones would have a hard plumbed copper pipe, and would stay full
automatically.

I would actually like to have the roll arounds for inside the containers so
that I could move them to the container/s in use. And for the space
between, a stationary one would be good.

Just wondering how the roll arounds work vs. stationary ones.

Insights?
