STULZ presents its latest innovation: CyberRow. The air conditioner unit is installed directly in the server room between the racks, where its horizontal air-flow provides precise, energy-efficient cooling. The major benefit of CyberRow is that it can be retrofitted regardless of the make of rack installed, thus offering greater flexibility of configuration, and making it just the right solution for small rooms too.
Not just one cool air-flow through a raised floor but two, streaming to the left and right and directly in front of the server racks. Those are the principles that STULZ works by to enhance the means of providing energy-efficient cooling for data centres.
With this product, STULZ is able to meet a wide variety of data centre operator needs. Installed directly between the racks, CyberRow blows out cold air horizontally and across the full server rack height to both sides, distributing it evenly and in a targeted manner around the data centre. This is a great benefit in terms of flexibility, because CyberRow is not reliant on building structures such as raised floors to distribute the air, as in the case of conventional air conditioning solutions.
The system can be very easily installed in any server room, because it is compatible with every make of rack. That makes CyberRow the right choice when retrofitting and installing specifically targeted additional cooling, and the ideal solution for rooms in which conventional systems cannot be used due to the building design.
Because CyberRow cools right where heat is generated, the air is transported over shorter distances. This means the system can be targeted closely where it is needed, over-dimensioning can be avoided, and energy can be saved.
Four systems for flexible cooling concepts
For even greater flexibility, STULZ offers the A/C unit in two sizes. Units are available in sizes of 1,950mm x 400mm x 1,175mm and 1,950mm x 600mm x 1,175m, and with capacities of 24kW to 55kW.
CyberRow offers two purely DX systems with compressor cooling, as well as a hybrid system whereby a water-cooled coil is added to the DX system. The water-cooled coil is connected to a re-cooling heat exchanger installed outside of the building.
As soon as the ambient temperature permits, the unit switches from cost-intensive compressor mode to the more resource-conserving Indirect Free Cooling mode via the re-cooling heat exchanger. In addition to the DX systems, a water-cooled CW variant is also offered.
Cleverly designed, easily integrated
CyberRow works as an AS, GS and GES system with energy-efficient inverter-controlled scroll compressors which can be infinitely adjusted according to the required load. The speeds of the A/C unit's three EC fans are also infinitely adjustable. In standard operation the fans run in parallel at low load, in order to minimise power consumption. This also enables them to respond rapidly to varying cooling system demands.
All the key functions of the A/C unit are controlled by the C7000 processor. The unit can be connected via an interface to any commonly used building services management system.
