Wright Line’s patent-pending heat containment system (HCS) offers a simple, scalable, and low-cost solution that contains and directs the heat exhaust from IT equipment through a chimney attached to the top rear of the data center enclosure. The hot air is ducted to existing CRAC units through a plenum ceiling or high air return. The system can cool up to 25 kW or more per enclosure without the expense of adding supplemental CRAC units to the data center.
