How large of a room will this 1 Ton Portable AC cool?

The WMC-2500 is a server room unit, it should not be used to cool a room. The math with cooling is every 1 ton of cooling will cool 400 ft.² as long as it's an insulated room with no more than 10 foot. ceilings. ... If you have any further questions please feel free to give us a call! Thanks.
