Cold aisle containment

Targeted cooling and higher energy efficiency!
Increase server performance by implementing cold aisle containment

Instead of flooding the Data Centre with cold air, the cold aisle containment system from Rittal effectively 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:
1. Cold and hot air cannot mix, warm air does not flow into the cold aisle.
2. The system can be operated with a much higher extracted air temperature.
3. Standard air circulation cooling units are operated at an optimum thermal efficiency level.

Standard market concepts compared to the Rittal cold aisle containment
Hot air extraction using a duct system
  • Complex and costly duct system.
  • Larger surface and height requirements.
  • Limitation of the raised floor height.
  • As a result, no uniform cooling air supply to the room area.
  • Cable management is made more difficult.
  • Limited rack positioning flexibility due to the air duct connection.
Hot aisle enclosure
  • Standard air circulation cooling units cannot be used.
  • Adequate air cooling only achievable with costly in-row chillers.
  • These require additional expensive floor space in the rack suite.
  • Poor working conditions for the operating personnel (high exit speed of the cold air and excessive noise caused by the fan).
  • Hardware racks not connected to the warm aisle enclosure impair the cooling result because of their heat emissions.
Rittal cold aisle containment
  • Use of standard inexpensive air circulation cooling units. Positioning outside the server area.
  • Even with low room heights, maximisation of the raised floor height for cooling air supply without flow losses.
  • Undisturbed and uniform air flow distribution of cooling air in the cold aisle guarantees high efficiency.
  • Favourable working conditions in the cold aisle due to low temperature, flow and noise load conditions.
  • Hardware racks not connected to the enclosure do not impair the cooling efficiency of the cold aisle.
