CyberRow - Intelligent Air Flow Control for more Efficiency in Rack Cooling


 CyberRow is an advanced precision A/C unit, which is tailormade for the targeted cooling of racks. In the CyberRow, innovative air conduction has been enhanced by state-of-the-art technology, which enhances the performance, flexibility and efficiency. Fluctuating server rack loads, space restrictions, lack of a raised floor, existing server technology - these are some of the tricky situations in everyday practice that the CyberRow has been specially developed to deal with.

CyberRow is a standalone A/C unit and is installed and operated independently from the rack. This complete separation of the rack and the A/C unit increases reliability and provides greater freedom for designing the layout in the data center.

STULZ CyberRow rack cooling systems are suitable for hot-aisle and cold-aisle capture in open and contained spaces.

CyberRow is available with 6 sizes and 4 different cooling systems:

  • CW-System (chilled water cooling),
  • AS-System (direct expansion),
  • GS-System (direct expansion and plate condenser) and
  • GES-System (direct expansion with indirect free cooling).

 CyberRow - Efficiency at a glance

  • Horizontal air conduction: The cold air reaches the rack via the shortest route.
  • STULZ C7000 controller: Monitors and controls all components inside and outside the A/C unit that are needed to generate cold air.
  • Up to 5 speed-controlled EC fans: Up to 5 speed-controlled EC fans, which can be controlled independently of each other for optimum adaptation to different return air and supply air temperatures
  • EC compressor: only for DX and GE units
  • Flexibility and compatibility: The CyberRow is available in four different cooling systems (AS, CW, GS and GES system with Indirect Free Cooling) and in three sizes.
  • Modernising cooling systems in existing buildings: Thanks to its compact size and universal suitability for racks from different manufacturers, CyberRow can also be used for trouble-free modernisation of cooling systems in existing buildings.
