Solutions for Saving Energy and Sound Sensitive ApplicationsS U P E R L O W S O U N DF A N T E C H N O L O G YThe NEW PMCQ Condenser comes standard with Super Low Sound Fans. They reduce the overall sound generationcompared to forced draft centrifugal condensers, and additionally reduce the energy consumption by 50%.Consult EVAPCO's selection software for unit sound levels. If a detailed analysis or full octave band datasheet is requiredfor your application, please consult your EVAPCO Sales Representative.SOUNDReduced Sound Levels and Reduced Energy Consumption versus Centrifugal Fan UnitsEVAPCO's Super Low Sound Fan on the PMCQ condensers utilizes an extremely wide chord blade design available forsound sensitive applications where the lowest sound levels are desired. The fan is one piece molded heavy duty FRPconstruction utilizing a forward swept blade design.Improved Sound Quality versusstandard straight bladed axial fan typesThe SUPER Low Sound Fan on the PMCQ condensers reducessound levels 10 to 13 dB(A) and eliminates audible bladepassing frequencies indicative of straight bladed axial type fans.Refer to the Narrow Band Spectrum graph which shows howstraight bladed axial fans produce blade passing frequencies –the same phenomena that produce the signature pulsatinghelicopter noise.The blade passing frequencies are audible spikes in soundpressure levels, but are not apparent in the octave band soundspectrum.PMCQ / LSCB Sound ComparisonsSound Pressure LevelsFanOpp.Motor Fan Opp. FanModel No. Power End Side End Side TopLSCB-400 22 58 66 57 56 63PMCQ-405 11 57 66 57 57 62LSCB-625 37 59 66 59 56 63PMCQ-613 22 59 69 59 58 63NOTE: Sound pressure levels in dBA 15 m from source• Reduced energy consumption compared to Forced DraftCentrifugal Condensers• Typical sound values equal or lower than Forced DraftCentrifugal Condensers of similar sizeThe Super Low Sound Fan on the PMCQ Condenser reduces soundlevels and fan power without compromizing the sound quality!Blade Passing FrequenciesSound Pressure Level (dB)Standard Axial Fan Forced DraftSuper Low Sound Fan Forced DraftFrequency (Hz)Narrow Band Spectrum Analysis10
