STULZ CyberWall data centre cooling solution

The STULZ CyberWall data centre cooling solution is designed for operators of large, colocation and hyperscale data centres.

It comprises a range of precision air-conditioning units specifically developed for facilities with separate aisles. Its horizontal airflow technology enables operation of high IT load densities, without the use of raised floors or side coolers.

In order to protect equipment and offer a good level of cooling, CyberWall is configured around fan walls with electronically commutated (EC) fans and integrated air/water heat exchangers. This allows a cooling capacity of around 100 kW per metre of wall length to be achieved and means that the efficient air conditioning of high power densities, as well as racks of 42U or more, is now possible.

The product 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, so that separation of cold and warm air is created. The system also fits into the existing service corridor, which allows the maintenance of air conditioners to be completed without the need for personnel to enter the server area.
