Aware recommends a ceiling mount for your data center as this will benefit better directional air flow (up and down) and consumes less space. The unit is also easily serviceable. The unit we have recommended could be installed on the floor like a tower if you prefer however we do not recommend floor installation for optimal air flow. Tower units only provide directional air flow from left to right. The height of the tower units is a problem as it does not normally circulate air above the top of the racks unless it is mounted very high on top of a base/stand. We experience this issue in our data center.
