Data Centres
Data centres offer data storage capacity for a variety of clients. Those centres are operational continuously as all that data must be available 24/7. Storing the data requires a large amount of servers which in turn requires enormous cooling capacity to keep working temperatures for the computers at an optimal level. A large number of chillers can therefore be found at such centres.
