Rittal cold aisle containment is a combination of door and roof components which facilitate consistent separation of the hot and cold air in the data centre.
Instead of flooding the data center with cold air, Rittal's cold aisle containment system traps the cool air exactly where it is needed directly in front of the air intake of the servers. Cold air is directed across the whole height of the enclosure ensuring that there are no hotspots 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, therefore there is an increase in system efficiency.
The special energy efficiency of the Rittal cold aisle concept has a simple and plausible explanation:
- Cold and hot air cannot mix, warm air does not flow into the cold aisle.
- The system can be operated with a much higher extracted air temperature.
- Standard air circulation cooling units are operated at an optimum thermal efficiency level.
CRAC system and cold aisle containment

By using Rittal cold aisle containment, climate control of the room (in conjunction with a CRAC unit) may be optimized for energy efficiency and cooling output.
Benefits:
- High energy efficiency
- Increased cooling output per server enclosure
- Easily retro-fitted to existing systems
- Protection of your existing infrastructure
LCP Inline and cold aisle containment

Application Example: Cold Aisle Containment with Rittal LCP Inline
In conjunction with the Rittal LCP Inline, cold aisle containment is a further option for the efficient dissipation of high heat loads from server enclosures.
Benefits:
- A raised floor is not required for climate control
- To accommodate higher heat loads per server enclosure
- Redundancies easily achieved
- Direct supply of cold air to your server and network components
