Utilising indirect air to air heat exchange techniques, the Excool system uses only outside ambient air and water to cool Data Centres using a natural and low carbon philosophy.

The heat exchange matrix is optimised for all year round Data Centre Environmental control. Water is introduced into the system to achieve design conditions in higher temperature external ambients.

Overall annual energy savings using Excool can be up to 95% of comparable old technology systems allowing overall PUE's below 1.1.
