Built for a lifetimeMaximum efficiency and reliability havelong been synonymous with KaeserCompressors. Our commitment to excellencedrives us to continually enhanceand optimize our compressed air systemsolutions. With a cutting edge researchand development team committed toproducing industry leading products,Kaeser constantly strives to offer lastingsolutions for our customers’ compressedair needs. The DSD series rotary screwcompressor delivers on all accounts.Kaeser’s unique Sigma Profileairend and intelligent Sigma Control 2system, combined with the latest one-toonedrive technology mean that our DSDcompressors can guarantee exceptionalenergy savings, without compromisingon durability or ease of maintenance.Our customers expect excellence and wemake it happen.Built to perform. Built to last. Kaesercompressors are built for a lifetime.EquipmentMaintenanceElectricity70% of Your Long TermCompressor Cost is ElectricityAnalyze the total cost of a compressedair system and you’ll realize that powercost is significant. In just one year itcould exceed the price of the compressoritself. Over a period of ten years, thiscould consume 70% of your overall airsystem costs. That’s why it is importantto investigate energy efficiency whenconsidering a new compressor or designingan air system.1Sigma Profile AirendOur single-stage, flooded rotary screw airenddelivers pressuresup to 217 psig,and features ourpower saving SigmaProfile design. Ourairends are precisionmachined andoptimized in size and profile to match the airendspeeds with their best specific performance (seeA Perfect Match curve).2True Direct DriveIn our design, the motor is directly connected tothe airend with a one-toonecoupling, providingmaximum transmissionefficiency. This true directdrive eliminates geardrive components, heat and power losses. It isalso maintenance free, increasing reliability anduptime. A cast housing is doweled and pinned toassure perfect alignment.3Premium Efficiency DriveMotorA Perfect MatchSpecific Performance (kW/100 cfm)Airend SpeedOptimum SpeedUnlike the competition, Kaeser Compressors makes many different airends to that we can applythem at their optimal speed and performance.Kaeser uses only premium efficiency TotallyEnclosed Fan Cooled (TEFC) motors with class Finsulation for extra protectionfrom heat and contaminants.Remotegrease fittings makemaintenance abreeze. Each of thethree motor windingsis actively monitoredthrough its own PT100 temperaturesensor. Standard voltages are 460 or 575 V(3-phase, 60 Hz). Other voltages are available.4Reduced Voltage StartingMagnetic Wye-Delta reduced voltage starting isstandard. This energy saving feature ensureslow starting current and smooth acceleration.

DSD Series451235Inlet FilterFluid Separation SystemWe protect our compressors with a two-stage,1 micron air intake filter.This extends airend lifeand fluid change intervals.The filter may be cleanedseveral times beforereplacement and is easilyserviced with no toolsrequired.Our separator tank has a 3-stage separation system that ensures very low pressuredrop, fluid carry-over (1-3 ppm), and extended filter service life.Our no-leak design features rigid steel piping, flexible connections and vibrationisolators. Each pressure vessel is ASME coded (CRN in Canada) and includes wetside/dry side fittings to check differential pressure, an easy to read fluid levelindicator, and our unique quick drain system.

Unique Air Flow DesignOptimizes CoolingIn Kaeser’s “split-cooling” design, twoseparate cooling air inlet zones forthe coolers and drive motor ensureoptimum cooling. Drawing ambient airdirectly across the coolers and motorthrough separate zones eliminates preheatingand results in longer lubricantlife and a cooler running motor. Thisalso results in much lower approachtemperatures, improving moistureseparation and air quality.To increase reliability and reducemaintenance costs, the coolers areconveniently located on the outside ofthe unit, where dust and dirt build-upare easily seen and can be removedwithout dismantling the cooler.Powerful radial fans pull air through thecoolers and create a vacuumwithin the cabinetthat effectively coolsthe motor even undersevere operating conditions.Top exhaust allowsfor convenient ducting and reduces thesystem footprint.Intelligent Control andProtectionTo protect your investment and ensurethe most efficient operation possible,we control this compressor with ourSigma Control 2. This intelligentcontroller comes standard with multiplepre-programmed control profilesso you can select the one that bestfits your application. Sigma Control 2monitors more than 20 critical operatingparameters, shuts the unit down toprevent damage and signals if immediateservice is required. It also trackspreventive maintenance intervals andprovides notice when PMs are due.Sigma Control 2 has superior communicationscapabilities. An Ethernet portand built-in web-server enable remoteaccess. ModBus, Profibus, Devicenet,and other industrial communicationsinterfaces are also available as plugin options for seamless integrationinto plant control/monitoring systems.See our Sigma Control 2 brochure fordetails.Extremely Low Sound andVibrationAll DSD models come standard withKaeser’s superior cabinet that featurescomplete metal enclosures with soundproofing liners and heavy-duty vibrationisolation. Using one-to-one direct driveand our unique cooing airflow designwith radial fans greatly reduces internalnoise and vibration.As a result, the DSD series runmuch quieter than other compressorsof similar size.Optimized EfficiencyIn DSD packages, one-to-one drive reduces thenumber of components needed compared toa gear drive unit thus increasing reliability andservice life.Kaeser has selected oversized airends specificallymatched to produce the requiredoutput in flow and pressure. Compared to compressorsusing small, high-speed gear-drivenairends, the DSD one-to-one drive provides triplesavings: no-loss power transmission, improvedpower consumption, and reduced maintenanceand related downtime costs.One-to-One Direct DriveAirend RPM = Motor RPM

DimensionsStandard VersionDSD 125, 150, and 175OptionsVariable frequency controlDSD compressors are available withSigma Frequency Control (SFC) toprovide superior part load efficiencyand steady pressure in applicationswith widely varying air demands.Standard features include EMI filters,line reactors, and galvanic separationcontactors for extra electrical systemprotection. SFC units also feature drivecabinet cooling fans and the latest inSiemens drive technology for reliabilityand efficiency.Water-cooledUnit with optional SFC. See SFC literaturefor more information.80-1/4”DSD compressors are available water-cooled with stainless steel, plate type heatexchangers as standard equipment. Shell and tube heat exchangers are availableon request.Heat Recovery92-3/4”Compressing air converts the electrical energy you buy into heat. DSD compressorsare available with a heat recovery option to recover up to 76% of this energy.They can come ready to be connected to an external heat exchanger or withinternal heat exchangers. Options include the plate type, shell and tube, or SWTheat exchangers. The SWT fail-safe heat exchangers provide extra protectionfrom process contamination in sensitive applications such as food, chemical, orpharmaceutical processing.When you consider that a 250 hp compressor running full time at 7 cents/kW uses over $187,500 per year in energy, the potential savings and benefits aresignificant.68”Air Discharge: 2½” ANSI FlangeDimensions are for reference only —please contact Kaeser for dimensionaldrawings.
