I have a small, rather dense server room that I need to cool. The total watts I have in there now is approx 12,000, plus the need to cool another unit that has a 2800 btu rating.

I would like to be safe and be able to cool 17,000 watts of computer equipment. My question is, what is the smallest unit I can put in that will hold me over for now, and what is the size unit I should put in to allow for my gowth.

humidity is not a problem b/c my systems can all operate between 10 and 90%

I have gotten conflicting quotes anywhere from 3 to 5 ton, two speed and one speed systems. What would you suggest?

I also have an Inergen fire supression system in there, just so you know

Thanks for the help
