Hot Aisle Containment
Hot Aisle Containment System (HACS)
Today’s data centre’s are increasing in density. More power and cooling is required to maintain availability to critical data. Maintaining availability and increasing densities whilst keeping the footprint of the data centre under control is the newest challenge facing most IT managers. UPS Solutions can assist in making high density applications possible whilst minimising footprint.
Mixing of hot and cold air streams in the data centre lowers availability of IT equipment, as well as reduces the efficiency of the air conditioning unit. Returning the warmest possible air to In-Row air conditioners increases the efficiency and capacity of the system. A hot aisle containment system ensures proper air distribution by completely separating supply and return air paths.
Hot Aisle Containment configurations trap the hot air in the hot aisle at the rear of the racks forcing it to be drawn back in to the hot air return of the Computer Room Air Conditioning units (CRAC’s). This means that the hot air cannot escape out into the cold aisle and mix with the cold air that the CRAC’s are producing.

- Hot-aisle containment for high-density configurations
- Hot air containment eliminates hot spots by preventing hot air recirculation into sensitive IT equipment
- Scalable densities allow for higher density cooling to be achieved by integrating the Hot-aisle Containment System with In-Row architecture
- Scalable design allows for quick deployment of high density clusters and addresses needs and future expansion with pay-as-you-grow architecture
The in-row cooling, which couples the power and cooling, minimises the mixing of the cool air with the hot exhaust air and provides more efficient cooling versus traditional cooling approaches. With this innovative approach, you can deploy high density applications anywhere, allowing you to support high density in a non-raised floor environment or optimize the existing performance in a raised floor environment.
The hot aisle is sealed off using locking doors and transparent ceiling tiles that extend the width of the hot aisle. Ceiling tiles are available for both 19" and 23" racks.
The containment systems prevent the exhaust air from mixing with the cool air, allowing the hot air to be neutralized. With high density deployments, this is critical since they have both a higher velocity as well as high volume of exhaust air. In tandem, the in-row cooling used with the containment system is designed to support power densities of more than 20 KW per rack. This is up to 4 times as much density as a traditional cooling method using perimeter CRAC units.
