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.
