Siemon has expanded its line of WheelHouse advanced data centre solutions in Africa to include comprehensive aisle containment solutions with both cold aisle containment (CAC) and hot aisle containment (HAC) options that significantly improve efficiency and cost-effectively expand capacity for today’s data centres.
By either containing and isolating the cold air supply (CAC), or by guiding hot exhaust to overhead return air spaces (HAC), the new aisle containment solutions prevent the mixing of hot and cold air in the data centre. This allows for higher temperature return air to improve the efficiency of existing cooling systems and reduce energy costs, while preventing over-provisioning of computer room air conditioning (CRAC) units.
Alternatively, these solutions cost-effectively expand the capacity of the data centre to cool higher heat densities, maximising both cabinet and data centre floor space without the need for supplemental cooling.
“Hotter return air temperatures facilitate heat exchange within cooling systems, improving power usage effectiveness (PUE) and reducing energy costs through lower fan speeds, higher chilled water temperatures and greater economiser hours. At the same time data centre equipment is being cooled sufficiently to maximise performance and life expectancy,” says Stuart Gray, product manager at Siemon. “For both new and retrofit situations, aisle containment systems are an economical way to prevent costly oversupply of cold air whilst enabling growth in data centre environments.
“To support this cold aisle containment can be used for a raised floor environment with no overhead return air space. Hot aisle containment can be deployed to maintain an overall cooler working environment outside of the contained area.”
Designed with robust seals for optimal thermal isolation, the new aisle containment solutions consist of CAC roof panels, HAC standing cabinet panels, single and double manual and self-closing doors and, end panels that have been designed for quick and easy on-site attachment to rows of Siemon VersaPOD, V800 and V600 data centre cabinets.
The containment systems are also compatible with Siemon’s SidePOD and Baffle solutions that support side-to-side ventilated active equipment. A range of accessories are available to complement the system, including filler panels to fill spaces where cabinets are not present, wall mount brackets for installation against a wall for a single cabinet row, vertical panel angled support brackets when attaching to the ceiling is not allowed, and riser brackets to raise the ceiling height within the contained aisle when using shorter (42U) cabinets.
