Phoenix NAP Mechanical Distribution

Designed for Uptime

Specifically configured to avoid single points of failure — that is the Phoenix NAP mechanical (cooling) distribution system. From N+1 modular chilled water plants to CRAH (computer room air handler) units that are N+4 each zone they are in, every component is constructed to have the highest levels of redundancy, ensuring maximum performance.

The bi-directional closed water loop is at the center of our design. Efficiently pumping in chilled water to our facility from two sides while removing datacenter heat, at full build out the loop features:

• Eight chilled water plants
• Dual headers passing through the chilled water plants
• Two N+1 secondary pumping modules
• Eight thermal storage tanks
• Nearly 100 CRAH units
• Dual make-up water tanks

This configuration will provide more than 5,700 tons of cooling to our datacenter facility. That is equivalent to nearly 3,000 households’ worth of cooling, based on an average usage of two tons per home. Bottom line? Equipment will be sufficiently cooled to stay online.

Free-flowing Circulation

Phoenix NAP has a 36-inch raised floor. Compared to a traditional datacenter that may have an 18- or 24-inch raised floor, the additional space enables CRAHs to circulate a greater amount of air and cool equipment. Furthermore, unlike many traditional datacenters, there is no power or data wiring under our floor, allowing for an unfettered air flow. The CRAH units at Phoenix NAP will circulate more than 1.6 million cubic feet of air per minute (CFM) through the entire building. Within our meet-me room, air is capable of being re-circulated every 20 seconds.
