Contained Cold Aisle
One of the potential drawbacks with 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.
With CONTEG Cold Aisle Containment 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.
With CONTEG Cold Aisle Containment 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.
When facing this type of design challenge it makes sound engineering and financial sense to form a physical barrier between cold and warm air streams. For existing installations with rows of racks with different heights or even with gaps was developed Modular Contained Aisle.
The contained cold aisle solution can be deployed where higher density loads are found to ensure that all available cooling air is directed to the cabinets. It can also be combined with CONTEG Side Mount Cooling Units to trap locally produced cooled air and ensure that all cold air produced passes through the equipment.
As
an option, the Contained Cold 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 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, should a fire be detected within a contained cold 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.
CONTEG
test data shows a significant improvement to airflow in the case of 83%
super-vented doors being used over standard perforated door types. In
order to make the best use of available cold air it is recommended to
blank-off any un-used space within the rack by using standard blank
panels.
Additionally, using an air separation frame
at the front of the rack will help to block unwanted cold air by-pass
around the mounting profiles leading to an improvement in cooling
efficiency for equipment that uses front to back airflow.

Recommended Contained Cold Aisle rack design
Front vented door enable the cold air to easily enter the rack whereas the rear vented door allow the warmed air easily leave the rack; recommended to use supporting products for proper air-flow within the rack - separation frame and blank panels.
- Front vented door (83% perforation rate) with multipoint swivel handle lock
- Rear vented door (83% perforation rate) with multipoint swivel handle lock
- Removable sheet steel side panels with lock
- Two pairs of 19" vertical sliding extrusions
- Top and bottom openings for cable entry; removable top plate (only RDF racks)
- Adjustable feet as standard; recommended plinth or plinth with filter
- Accessories for Contained Cold Aisle solution
Modular Contained Aisle
- Reduction of hot and cold air mixing by eliminating cold air by-passes
- Product provides balanced air distribution along the entire rack elevation
- Solution does not require equipment shut down to retro-fit in operating data centers
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
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. Modular Contained Aisle can work with standard aisle
door or with PVC foil strips instead of standard door. More information ...Data Center Cooling
Principles of contained cold aisle arrangement require a central cooling system or in-row side mount cooling system. Since 2008, CONTEG is an official partner of the world's leading manufacturer of precision cooling solutions.
Side
mount cooling units are designed to address the very high density heat
loads with cooling capacity up to 36kW. In-row side mount cooling architerure is designed as open and
gives high degree of design flexibility to ensure that the cooling
needs of the equipment can be met. The units are connected to the central chilled water system, (or micro-condensers in the case of DX units) and control the temperature and humidity of the output air. Piping for the side mount units can be laid in advance and then the units added as the facility is built out thus saving initial infrastructure investment costs.
Data Center Cooling
Deployments are ideally suited to deployments which utilise
central room cooling with locally positioned close control units. Since
2008, CONTEG is an official partner of the global leader
in precision cooling. Please, feel free to contact us. We will be glad

When preparing a complex network project, consultants, designers or the end user IT department can benefit from the advice or support of our product managers. Incorrect estimation of the requirements for a project, whether under-sizing an air-conditioning system or simply failing to allow adequate space for cable management, can have a drastic impact on the reliability of the installed equipment and the functionality of the facility as a whole.
With our product managers´support you will be able to select the most suitable rack type for installation of any instrumentation, its power supply, cooling or just maybe only the correct system of cable management.
