The photograph above is indicative of an ideal hot aisle without any perforated air flow tiles.

Hot aisles should be hot and cold aisles should be cold.

Tip: Extend your high air flow grates (such as the Infinity grate) one tile beyond the length of each cold aisle equipment row as vertical air flow is the best air flow diverter to prevent bypass airflow especially for high heat generating equipment.

Creating dedicated “hot and cold aisles” or “rack and row” data center equipment placement configurations with the PlenaForm^® baffle System increases the static pressure delivering a higher volume of cooling through perforated tiles and at a further distance from the CRAC units. The Venturi effect is attained and air pressure is increased in the dedicated cold aisles. By installing PlenaForm^® baffles,  air flow distribution may be directed more efficiently from the CRAC units for maximum equipment air cooling or air blocking requirements in a data center raised floor plenum space.
 
Installing the PlenaForm^® baffle system to direct air flow from the “source of the air” plenum level, a data center manager can better achieve a thermally tuned data center. Integrating PlenaForm Systems into the data center design also helps to mitigate thermally associated risk to equipment hardware.
 
The key word here is high density computing and PlenaForm^® Systems helps to solve thermal imbalances in your data center environment simply and inexpensively!

PlenaForm baffles can also be installed in the ceiling plenum. Create dedicated return air paths in the ceiling plenum for more efficient heat return from the hot aisles to the CRAC unit intake heads.

You can even make CRAC extension intake heads with PlenaForm baffles attached to a drop ceiling with removable clips.
