MINIMUM PRESSURE VALVESHIGHER COMPRESSED AIR QUALITYGREATER RELIABILITYLONGER LIFETIMECompressed air treatment systems are always designed for specific flow rates.They can only function at their best within a certain range.pp p x x V V = = konstant constantVIf the compressor startup takes place without anyAbschaltung off-loadAuslegung on-load(laying out)Druckband pressure bandpressure, there is a danger that oil and water dropletswill overrun the filter/dryer barrier.This “overrunning“ of compressed air treatment systemscan create serious problems.Anfahren starting periodder AnlageZeit timezulässige optimumGeschwindigkeitflow speedOil in the networkWater in the networkMembrane dryer:insufficient expansion gradientWater separatorand filter:Condensate in the quietzone is entrainedCoalescence filter:separated droplets areentrainedActivated carbon adsorber:contact time for oil vapouradsorption too shortRefrigeration dryer:contact time in heatexchanger too shortAdsorption dryer:contact time in desiccant bed too shortThe solution:MINIMUM PRESSURE VALVESOperational reliabilityAdsorption dryer:increased abrasion/loss of desiccantreduces dryer efficiency. Higher costdue to dust filter clogging up quickly.Filter:Tensile stress on the drainage layercan lead to tearing or complete lossof drainage function
