Stulz CyberRow air-conditioning units

CyberRow air-conditioning units can be used by data centre managers for cooling of higher heat-density server racks. The units feature variable-speed electronically controlled fans which blow cold air horizontally and parallel to the rack face, ensuring uniform cool air distribution over the entire rack height.

The in-row air-conditioning units distribute air horizontally along the row of racks rather than away from the racks. The individual units are positioned between the racks so that they can dissipate extreme heat from the servers. As the cold air is transported in two directions via outlets on the side of the units, it is more likely that the cold air will enter the server rack inlet and not mix with room air, leading to a more effective and efficient cooling approach.

The units are available in four configurations: air-cooled, condenser-water, chilled-water and free-cooling up to 56 kW in capacity. The air-cooled version includes an inverter-driven brushless DC compressor providing up to a claimed 30% energy savings compared to digital-scroll compressors and other AC compressor technologies. The free-cooling version claims up to 60% savings in power consumption.
