The Coolerado looks like a self-contained evaporative cooler with a heat-exchanger.

What are the costs and specs on such equipment?

The specs seem fairly detailed (at least to a non-HVAC person) on their website [IE: 1].

Cost on the other hand doesn't seem to be readily available (my guess is expensive since they seem to be targeting businesses vs consumers).
