Flowgridstandsfor efficient noiseprotection features in cooling,ventilation andair-conditioning technology.Thisoffersa future-oriented solution for the problem of high-performancetechnology generating disturbing noise: Flowgrid foraxialandcentrifugal fans.Thegrille on the air-inlet side drasticallyreducesthe noiseemissionsandminimisesdisturbing low frequency tones.There areoften problemswherever people and technologysharespace.Themovement of air, for example,often goeshand in handwith noise.With Flowgrid, noise-generatingdisturbancesin the fan inflow area thing of the past.The scaleof possibleenergysavings- or efficiencyenhancementand noise reduction - that can be achievedby fittingan optimal diffuser such as the Axitop on a conventional heat exchangeris substantial. For example, exchangingastandardguard grille fan for an axialfan with support grille, guard grille and Axitop diffuser makessavingsof up to 27%possiblein energyconsumptionand at the sametime up to 7.2 dB(A)lessacousticcapacity.

FLOWGRID SYSTEM

Composedby a finned coil with cooper coil and aluminum fins, with servo-controlled 3-way valve. The controllerregulates the valve position by suppling the Free Cooling coil when the climate conditions allow it. The waterconditioning iscooled by the external air decreasingthe useof the cooling circuit.TheCompressorsstart to partializetill to stop when the free cooling is activeand when the water temperature comingfrom the FCcoil iscloseto the set point.In this casewe got the complete free cooling and the water temperature control comes by means of continuousregulation of the fans rotation speed.In order to optimize spaces,capacityand noise pollution, unit dimensionscould be different by the standardmodel.
