STULZ CyberRow - Comprehensive Rack Cooling
- STULZ CyberRow
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 centre.
STULZ CyberRow rack cooling systems are suitable for hot-aisle and cold-aisle capture in open and contained spaces.
CyberRow is available with 2 sizes and 4 different cooling systems:
- CW-System (chilled water cooling),
- A-System (direct expansion),
- G-System (direct expansion and plate condenser) and
- GE-System (direct expansion with indirect free cooling).
- Data centre with CyberRow A system
CyberRow - Efficiency at a glance
- Horizontal air conduction: The cold air reaches the rack via the shortest route.
- Electronic control: Monitors and controls all components inside and outside the A/C unit that are needed to generate cold air.
- 3 EC fans: Independently, infinitely adjustable EC fans ensure maximum efficiency
- EC compressor: Infinetely adjustable for precise cooling capacity and 50 % lower power consumption when starting the compressor, thanks to soft start function
- Electronic expansion valve: Finely controls the cooling capacity within a few seconds
- Flexibility and compatibility: The CyberRow is available in 4 different cooling systems (A, CW, G and as a GE system with Indirect Free Cooling) and in 2 sizes.
- Modernising cooling systems in existing buildings: Thanks to its compact size and universal suitability for racks from different manufacturers, the CyberRow can also be used without problem to modernise cooling systems in existing buildings.
