Abstract: A cooling unit (80) comprising at least one cooling coil, at least one fan (86) for circulating air through said at least one cooling coil, and a housing containing said at least one cooling coil and fan, wherein said housing is sized to fit within an IT server rack and is arranged for attachment to said rack. This allows a cooling unit to be fitted to an IT rack conforming to EIA 310 D specifications. Such racks, in particular the 19? configuration, are commonly found in datacentres and computer rooms and therefore the provision of a cooling unit which can be inserted into such a rack allows an existing datacentre to quickly be adapted to take advantage of the latest in computer room cooling methodology. The cooling unit (80) can be mounted in a semi-recessed configuration with the at least one fan projecting beyond the rack boundary to reduce power consumption.
