In the Contained Aisle design the cold air is produced by central cooling
system with perimeter mounted CRAC/CRAH units. The raised floor is used
as a cold air handling plenum and the cold air enters the aisle via perforated floor tiles. If, from any reason, the raised floor cannot be used, the cold air can be produced locally by in‑row side mount cooling units installed directly in the row of racks. This solution is currently very popular as it can address very high heat loads.
By using the roof the cold air is trapped in the contained aisle, the roof also efficiently blocks the hot air to re‑enter the aisle
Dual leaf opening door allow access into the
contained aisle, it can be equipped by automatic
handling systems optionally
Cold air is delivered to the cold aisle using the raised
floor as a cold air handling plenum, the hot air is blown out on the back side to the data center room, roof and doors are used to prevent mixing hot and cold air
polycarbonate panels on
the top of the roof. Vertical side
sections of the roof feature PVC foil strips, which can be easily cut to the required length. Flexible Contained Aisle can work with standard aisle door (see above) or with PVC foil strips instead of standard door. Contact us for more information
Modular Contained Aisle
system is available upon request. This system is the ideal solution when a row of racks with different heights or even with gaps because of missing racks is required to be contained. System is based on self‑supporting construction with clear
should a fire be detected within a contained aisle, you would want to ensure that doors are closed to contain the suppressant within the affected aisle. Obviously, this requires co‑ordination with the designers of the access control, building management and fire suppression system but gives you an idea of the flexibility that is available with the CONTEG contained aisle system.
designed to support racks of 42 and 45U heights. The transparent sections are manufactured from clear poly carbonate to ensure that light can pass easily into the contained aisle.
As an option, the Contained Aisle system can be
fitted with automatic door handlers and integrated with the access control system, environmental monitoring system and fire alarm to ensure that the doors are opened or closed automatically. For example, in the case of a cooling system failure it would be beneficial to open the doors of the cold
aisle to allow environmental air to be available to the equipment for cooling and to limit the rate of equipment temperature increase. However
With CONTEG Contained Aisle solution, the modular containment system is used to physically separate cooled air from hot exhaust by forming a cold plenum space and preventing mixing of hot and cold air, thereby eliminating hot‑spots. The contained aisle solution can be deployed where higher density loads are collocated to ensure that all available cooling air is directed to the cabinets. It can also be combined with CONTEG Side Mount Cooling Units to produce cold air locally and ensure that all cold air produced passes through the equipment. The system is designed to work with RSF/RDF/RHF/RSB/ROF rack series the basis of CONTEGs data center solutions, and it is
One of the potential drawbacks of the Hot / Cold Aisle approach is the possibility of warm air recirculation due to insufficient static pressure within the raised floor or a lower than optimal ceiling clearance preventing adequate stratification of warm air. Of course, whether this actually occurs or not depends on many variables, however when facing this type of design challenge it makes engineering and financial sense to form a physical barrier between cold and warm air streams
