In this way the mixing effect betweencooling unit cold air and the electronic equipment hot airis denied resulting in a doublebeneficialeffect: the racks are fed by cold air where it is needed and the air conditioner treats only the hotair maximising its temperature inside the racks, high efficiency of the cooling equipment, hot spot absencein the site: distributing the air in a smart way is very energy!

4 The use of the freecooling gives the possibility to stop the compressor and condenser fan, usingthe external fresh air to cool the site: the annual energy absorption, requested to cool the site,goessensibly down. The0---100% finemodulation allowsto keep constantly thedesired itsown airdistribution (only hot airis exhausted), Liebert HPWdownflowversion, extends the yearly freecooling use, increasing the energy site reliability! Liebert HPW, equipped withe the Emergency Cooling feature, does not stop the operation evenin case of mains failure: fed by 48 V DC emergency supply from back up systems, Liebert HPWautosets its parameters to ventilate and maximise the freecooling to keep the indoor temperaturebelow the shut down limit, reliablity of the site means also reliability of the unit.
