A/C

[Gerald]

Salty........if the vending machines are just being stored and not running [ie. putting out heat], get a small A/C unit.

A 1/2 ton [6000 BTU] should be plenty big enough. Something smaller could keep it cool.....but would need better discription / information. If the vending machines are running.....then I would need more info.

Yes, too big is not good. The unit needs to run long enough to remove the humidity from the air......not just cool the building quickly.
