By using Rittal cold aisle containment in conjunction with
the Rittal CRAC system, you can optimise climate control
of the room in terms of energy efficiency and cooling
output.
 High energy efficiency
 Increased cooling output per server rack
 Easily retro-fitted to existing systems
 Protection of your existing infrastructure
 The Mean Time Between Failures (MTBF) of existing
systems can be significantly extended
Instead of flooding the room with cold air, this Rittal concept
routes the cold air directly to the equipment via the cold
aisle. Cold air is directed across the whole height of the
enclosure, ensuring that there are no hot-spots, and the hot
air is exhausted out of the system. Due to the cold aisle
being contained, there is no chance of the hot exhaust air
mixing with the cold inlet air, leading to an increase in sys-
tem efficiency.
The outstanding energy efficiency of the Rittal cold aisle
concept has a simple explanation:
1. The intake air (cold) and waste air (hot) cannot mix.
2. The system may be operated at a significantly higher
temperature level.
3. Thanks to the increased temperature difference between
the intake air and waste air, the cooling performance and
efficiency of the climate control units are optimised.
