2 Emerson NetworkPower products have traditionally set the industry standards. But today s world requires more thanjust environmental control and reliability; it requires increasingly higher levels of overallperformances. While still offering unmatched environmental control and reliability, the new LiebertHPM range raises the bar of performance in Precision Air Conditioning setting new standards interms of Energy Efficiency, Compactness and Sound new Liebert HPM range is available in a number of airflow versions: with upflow, downflow anddisplacement airflow patterns across a full range of Cooling modes: direct expansion, chilled water,freecooling, dual fluid and constant (for an ultra high temperature and humidity control and airfiltration).

3 OVERUNDERThe product conforms to European Union directives2006/42/EC; 2004/108/EC; 2006/95/EC; 97/23/ECUnits are supplied complete with a Test CertificateConformity Declaration and Component HPMunits are CE marked as theycomply with the European directivesconcerningmechanical,electrica l,electromagnetic and pressure Quality Management Systemof Emerson Network Power Performance AirConditioning has been approvedby Lloyd s Register QualityAssurance to the qualitymanagement system standardISO 9001:2000 EmersonNetworkPowerpartecipates to Close Control AirConditioners Eurovent CertificationProgramme.

5 Maximise efficiency by operating at low levels of energy can be further enhanced by the use of Electronically Commutated Fans (EC Fan) reducingpower input by 35%.We underline the complete range with all models in Displacement version and in down---flow version achieves the highest levels of efficiency (EER is 20% better than industryaverage). The fan in this case is positioned upstream of the evaporator optimising airflow over thecoil. Alsoin the Underversions, silencercartridgescanbeused tofurther reducethe sound pressurelevel by up to a new Liebert HPM range has been designed to have the smallest possible overall footprint.

6 Thecompactness of the unit is fully evident for some capacities. For instance:---in the smaller sizes (S05 and S06) where the air outlet plenum is integrated in the unit bodyin a depth of only 400 mm;---in the S23, where 23 kW in direct expansion mode have been reached with footprint of 750 x750 the M29, where 29 kW have been reached with footprint of 1000 x 850 mm---in the M47, where 47 kW, single circuit, have been reached with a footprint of 1750 x 850mm;---in the M56 and M66, where in the 1750 x 850 mm footprint we have upflow and downflowconfigurations for air and water cooled the L83 and L99, where in the 2550 x 890 mm footprint we have downflow configurationsfor air and water cooled sound levels are the result of fan design, optimised airflows and doubled skin insulated to design detail means low operational costs including product maintenance throughhighlevels of reliability and a service friendly design.

7 As an example, all the crucial parts of therefrigeration circuit ( : thermostatic valves, sight glasses and liquid line driers) are groupedtogether and accessible simply by opening the front EfficiencyP l u g --- i n Fa nAll Liebert HPM Units are equipped with plug fans:direct driven centrifugal fans with backward curvedblades and an asynchronous external rotor new generation of these fans with specificallyshaped blades,designed especially fortheuseinairconditioning cabinets, features a very highmechanical efficiency over a wide operating addition, sound radiation is free of tonal noise atthe impeller suction and discharge fans are designed to have the maximum power capacity at an intermediate operating pointtherefore there is no risk of motor overloading.

8 The fans are not dependent on a minimum backpressure, as is the case with most centrifugal direct driven fans with forward curved to the use of plug fans the Available External Static Pressure is adjustable on site duringcommissioning, with a range from 0 to 450 Pa insome models, according to the Fan (Plug---in Electronically Commutated Fan)The largestcapacity LiebertHPM unitscan be supplied with anexclusive fan type, this enables you to greatly increase theunit s efficiency and therefore significantly reduce fans [Electronically Commutated DC motors] have theadded advantageof higher fan shaft motor efficiency: from45% of 1--- phase motors, to 65% of 3---phase motors and to85---90% of EC fans.

This means the EC fan option features a truesoft by the frequency converter, the advantages are evident and the input power is clearlyinferior: from13 to 38% as a function of the working internal electronics of the EC fan are integrated into Emerson Network Power EC fan design allows a new approach in regulating environmental parameters within HPAC applications.

10 To name a few:Dconstant air volumeDconstant external static pressureDsound emission optimisationDpower input optimisationDcooling capacity regulation (on request)This enables each system to be optimized for the features are available from standard Liebert HPM Units supplied with the EC fan option andwe can summarized that with two words: versatility and Exchanger Section:Net Sensible Capacity mattersEfficiency is a fundamental requirement in allapplications today. Even more so for technologicalapplications where the operational costs are by far themost significant consideration.
