Cold aisle containment systems use doors at aisle ends, ceiling panels or lids above racks, and structural frames to create enclosed zones where cold supply air flows directly to IT equipment intakes. Without containment, cold supply and hot exhaust air mix throughout the data. Cold aisle containment can be used with or without conventional raised floor cooling. It is easily retrofitted into existing raised floor data centers and works in tandem with the raised floor as well as with extreme density cooling systems to produce highly eficient cooling solutions. When implemented correctly, they improve efficiency, reduce energy consumption, extend equipment life, and enhance overall reliability. At its core, it strategically separates the cold air—the lifeblood of IT equipment—from the hot air that servers and other.

Cold Aisle Containment isolates the cooled supply air from the cooling units. The aisle containment system is a modular rowbased thermal containment solution, which separates cold and hot data center air streams to and from equipment.
