GERMANY: The new CyberWall from Stulz is said to ensure reliable operation of high IT load densities in data centres, without the use of raised floors or side coolers.
Designed for operators of large, colocation and hyperscale data centres, it comprises a range of precision air conditioning units employing horizontal airflow technology for facilities with separate aisles.
CyberWall is configured around high performance fan walls comprising electronically commutated (EC) fans with integrated air/water heat exchangers. This is said to allow a cooling capacity of around 100kW/m of wall length to be achieved.
With data centre white space now at a premium, the CyberWall has been designed so that indoor air handlers with cold water connection can be mounted in rows or stacked without gaps – making use of all available wall space and optimising system performance. Mounted at the aisle end, where they supply individual rack rows horizontally with cold air, the warm aisle is separated by a containment system with a ceiling duct to separate cold and warm air. The CyberWall system also fits precisely into the existing service corridor, allowing the air conditioning maintenance to be carried out without the need for personnel to enter the server area.
Stulz CyberWall modules are said to achieve a cooling capacity of 220kW, with 16°C water inlet, and an airflow rate of 55,000m³/h per air conditioning unit.
