SCREW COMPRESSORS

Energy costs need not go off course: because BOGE’s energy efficiency solutionsoffer a number of options that save energy.It is calculated that energy costs account for around 75 percent of the lifetime costsof compressed air generation. This makes energy optimisation essential for anycompressed air user. Significant sustainable savings can be created by continuallyauditing and optimising your installation. You should therefore rely on a partner who,as an energy expert, is ready and able to support you before and after your decisionto purchase compressed air products. Welcome to BOGE!INTELLIGENT SAVINGSPerfectly controlled output: BOGEfrequency controlled screw compressorsWhen there is a fl uctuating compressed airdemand, the BOGE frequency controlled screwcompressors works strictly in accordance withthe compressed air demand by producing theexact volume of compressed air at the pressurerequired.The volume fl ow is continually adjusted between25 and 100 percent – correctly specifi edfrequency controlled compressors shouldeliminate expensive idling times and even out airdemand fl uctuations. Energy costs can thereforebe reduced considerably.When a frequency controlled compressor is usedalongside a fi xed speed compressor additionaladvantages can be achieved. The fl exible speedadaptation of the airend also allows for pressureadaptation. Changing the pressure value of thefrequency compressor automaticallysynchronises the output quantity. A 13 barmachine can therefore be transformed into an 8bar machine yielding a correspondingly higheroutput – without any expensive remodelling ordesign related modifi cations. All pressures andintermediate pressures are available with thebest possible outputs.It takes little or no investment for a compressedair user to save as much as 30 percent of theircompressed air related energy costs. Be sure totake advantage of BOGE’s energy effi ciencysolutions to save energy costs. Examples:Leak detectionA single 2 mm diameter leaking hole causeslosses of 260 l/min – this equates to severalthousand Euros a year of energy costs.Comprehensive leak detection from BOGE willidentify any leaks within your compressed airnetwork.Heat recoveryMost of the energy used to generatecompressed air is rejected in the form of heat.This heat can be recovered: e.g. for spaceheating or for the heating of domestic water. Upto 85 percent of the input electrical energy canbe recovered: Our energy experts will be pleasedto advise you!AIReportDoes your compressor station still meet yourspecifi c site requirements? Oversized or obsoletecomponents can be the source of high energycosts. The AIReport system helps to detect weakpoints within a compressed air system bymonitoring compressed air generation, treatmentand distribution over a set period of time (e.g.one week, two weeks or even a month): this toolwill help you save energy!Savings potential of up to 30 %is possiblewith a frequency controlledcompressor:• minimised idling time• pressure reduction• load cycles virtually eliminated.The BOGE sign for efficient compressed airsolutions: Wherever it is displayed, users canbe assured of a particularly effi cient BOGEsolution helping to save a great deal of money!Screw Compressors 9
