A Data Center Chiller is a highly specialized cooling system used to combat one of the greatest threats to computer and data integrity — excess heat.

Data center chillers must operate 24/7 to keep closely packed racks and cabinets of heat-generating equipment cool at all times. Without chillers to continuously cool the water used in the HVAC system, temperatures would quickly rise to levels that could corrupt mission-critical data and destroy hardware.

To maintain uptime, data center providers should ensure that their chillers have an independent generator in the event of a power grid failure. Just as any data center should have backup generators to support servers and other systems if external power supplies fail, attention should be given to delivering emergency power to the chiller itself. A series of smaller chillers, each with independent power supplies, may offer the best balance of redundancy and efficiency, along with effective disaster recovery preparation.
