These packs are well known for PC server rooms, which regularly have no windows, however could be utilized in any room with a fitting roof. The steel board has just a single port, so assuming that a double hose arrangement is wanted, two packs would be required. There are convenient forced air systems, for example, the EdgeStar Server Cool, which can be utilized in one or the other single or double hose arrangement. Presently this unit is intended for drop tile roofs, yet I see not a great explanation it couldn't be utilized for other roof types. With a sheet rock roof, for instance, assuming an opening was cut sufficiently huge for the association port, and the board put over the roof, that ought to work as well.
