  • CyrusOne Zero Water Consumption Cooling: No water is consumed to cool this facility (such as water towers or evaporative cooling). Minimal amounts of water are used for humidification and facility maintenance. This facility uses highly efficient chillers, variable frequency drives, and energy-efficient CRAH units to achieve high efficiency air-cooled chilling.
  • Regional Water Stress: The London area currently faces high water stress, which is projected to continue in the future. Unlike many other data centers, CyrusOne’s London I facility does not use water for cooling and is therefore insulated from this regional water risk, both current and future.
