What is a cold aisle containment system?


Cold aisle containment systems (sometimes referred to as cooling systems) are designed for server and network cabinets, and other computing equipment in data centres, IT server rooms, or office environments, to maximize cooling predictability, capacity and efficiency. Containment systems restrict loss of cold air and prevent the mixing of cold and hot air (generated from server exhausts) within data aisles.

By limiting the loss of cold air generated by your air conditioning unit (ACU), and preventing hot and cold air from mixing, cold aisle containment systems keep servers and important IT equipment operating at safe, ambient temperatures without the need to work your ACU harder to cool the data aisle.

Cross-Guard’s Coolgenic cold aisle containment system is highly versatile – it can easily be modified or re-installed to suit your changing needs. By installing the system, clients optimise the efficiency of their data centre and save money. If you’d like a more in-depth definition of a cold aisle system, you’re advised to check out our about cold aisle containment page.

  • Cost effectiveness

  • Extended IT equipment life
  • Lower carbon emissions
  • Reduced hot spots
  • Favourable return on investment (ROI)

Components of a cold aisle containment system

A cold aisle containment system isolates hot and cold aisles from each other through using doors and a roof to form a pod around the cold aisle. Infill panels can be used to fill in any spaces, ensuring a full seal for the enclosure.

Cold aisle containment doors are used to seal the data cold aisle in combination with a cold aisle containment roof. There are different cold aisle door options from secure Connexions doors to bi-sliding, easy access cold aisle doors. Our Coolgenic cold aisle doors page provides a more in-depth summary of the options available.
