DATA CENTRE COOLINGThrough a history in close control, we have developeda broad and deep understanding of how to achievedata centres goals and ambitions.2
» Data centres are expanding and improvingDo not let your climatelimit youFläktGroup are involved and experienced in a wide variety of industries; from coolingtowers and large volume air handlers to office-based comfort cooling. We use this vastpool of knowledge to supplement our extensive history within the industry to continuallydesign, innovate, redesign and improve our products to enable your operations to thrive.Data centre design is no longer conventional or singular. With an industry focused ongreater efficiency and productivity, techniques and innovations such as pre-fabrication,modular design, aisle containment and many others now have a larger prevalence.These new innovations sometimes present challenges for the cooling and control ofthe air. Our close control range, called DENCO Products, is created in harmony withthese innovations to achieve your desires. The designs can address your requirements,whether that would be data centre redesign, need for scalability, highest performance ormaximised use of ‘freecooling’.The best data centres managers not only have to account for the present demands oftheir site, but they also plan and prepare for any number of future demands. They needequipment that can account for today, tomorrow and the next 10 to 20 years. DENCOproducts are devised with this in mind by utilising EC technology, inverter compressorsor other variable technologies so that they only work as hard as your servers. All theseaspects help to improve the metrics that you view your data centre performance againstand also help your PUE value progress towards to 1.With international locations of factories, sales offices, contacts and support, we can bewherever you, your data or your site is located.A trusted,experienced supplier: D ecades of experiencein close control industry L arge variety withinproduct portfolio C omponents with thelatest technology Efficiency focused design S imple system integrationand combination I n-house maintenanceand service capabilities3
Row-DENCO MEETING YOUR FUTUREDEMANDS, TODAYKey features: Rear to front airflow with multipleconfigurations available: no raisedfloor or suspended ceiling requiredfor airflow leaving plenty of spacefor your services. Direct expansion (R410A) andchilled water variants available. White panels to improve roomillumination, black panels areavailable as an option. Hot Swap fan technology:replaceable even during operation.4The data centre industry is no longer static; designers and managersmust consider both the existing requirements for performance andoutput. They must predict the future for the data centre. They needscalability, adaptability, dependability, consistency and simplicity toallow for their data centre to grow and evolve efficiently.ScalableRow-DENCO is small, effective and due to its airflow design, it can be grouped withsets of servers. This allows you to order and install just in time for your data centre’sgrowth and with multiple airflow configurations, it can grow in any direction.AdaptableRow-DENCO is a highly adaptable method for expansion of an existing data centre.The design requires no floor or ceiling void and has a small footprint (between0.30 and 0.36 m²). It includes easy and simple connection points that allow forfast installation from either above or below.
Slim design Electronic expansion valve Graphics based display SHR 1 Small footprint High EER Inverter compressors EC FansDependableRow-DENCO is easy for finding space for an N 1 configuration. The units can benetworked together, allowing for a duty-standby configuration setup. The fans, asstandard, operate an internal ‘running redundancy’, therefore if a fan needs replacing,the others can increase their speed to cover the cooling requirement whilst you canperform a hot swap.ConsistentRow-DENCO is available as both direct expansion and chilled water units, but sharethe same design principles and features: mechanical connections available at the topand bottom, humidifier available for both, casing sizes and airflow configurations arethe same for both types.SimpleRow-DENCO units make the delivery, installation, commissioning and maintenanceas straight-forward as possible. Whether by using integrated wheels to give easypositioning on your site or good accessibility to all internal components for maintenance. Row-DENCO, by design, helps lower risks to the room’s performance witheach airflow localised to particular servers.5

What you need,only when you need itDirectandscalableDesigned to be considerate for the futureBy placing a Row-DENCO unit amongst or alongside your servers, it allows for a shorter airpath which helps increase the number of air exchanges per hour and allows for a highertemperature gradient. Scalability is a key benefit of Row-DENCO. Data centre designs mayevolve and expand, Row-DENCO allows for incremental increases in cooling requirements.8
» Unit configuration and air pathsTO SUITYOUR NEEDSFront DischargeLeft and Right DischargeFront discharge is possible using either a 1,000 mm casing or1,200 mm casing (shown above). Warm air is drawn from the hotaisle and then cold air is delivered directly out of the front of theunit, allowing for the air to diffuse back to the servers.Left and right discharge uses a 1,200 mm deep case. As theRow-DENCO unit extrudes into the cold aisle, the air is deliveredacross the face of the servers through grilles on the side panels.The front door has no grille, therefore the air is forced horizontally.Left DischargeRight DischargeLeft discharge uses a 1,200 mm deep case. It is similar to the leftand right discharge design except with one grille is blocked.Typically these designs would be used for the end of a server rack.Right discharge uses a 1,200 mm deep case. It is similar to the leftand right discharge design except with one grille is blocked.Typically these designs would be used for the end of a server rack.9
» Supporting your cooling requirementsOUTDOORUNITSA condensing unit would perfectly compliment your direct expansion indoor unit. Itcomes with inverter driven hermetic scroll compressors that use R410A to provideexcellent energy saving. Part load operations represent 75 % of operation time, thereforebeing able to operate relative to this demand provides excellent energy efficiencywhen compared to traditional ON/OFF technology. Other equipment includes filter drier,oil separator, sump heater, EC fans (optional) and anti-vibration mounts (optional)to ensure a quiet, smooth and efficient operation. Winter start kits are available toenable operation as low as -35 C.Condensing unitCondensing Units DataPower051071121Fan power consumption¹kW0.310.601.20Compressor power 90255AirflowWeight and DimensionsDepthWeight2We reserve the right to make technical modification without prior notice.¹ Max power consumption2Net weight approximation; may vary depending on options selectedWe have a vast portfolio of products that can support your system.
