We’ll listen to what you need.Then we’ll use our decades of leadership inthe air systems market to help you designthe best compressed air system for yourapplication.Today, we’re the only manufacturer that cansupply you with energy-efficient compressorsin all three available technologies: rotaryscrew, reciprocating and centrifugal. Andsince each technology has its benefits,we can help you select the one that worksbest for your application.3

Digital ControlOur exclusive digitally controlled steppermotor inlet valve system precisely matchesthe airflow to the system demand. Just setthe preferred system pressure and the builtin Intellisys microprocessor controller takescare of the rest.To further reliability the inlet control systemrequires no maintenance. There are nopressure switches to manually recalibrateand no valves that can stick open - and, asa matter of fact, there are no manualadjustments required during the courseof normal operation.100Energy Saving ControlSystem% FULL LOAD POWERStraight ModulationControl70We equip each compressor with notone, but three separate control modes:On-line/Off-line, Upper Range Modulation,and Auto Control Select. Simply set theIntellisys controller to the desired controlmethod, and the microprocessor doesthe rest.GeometryController50Intellisys ControlOn Line/Off Line200204060% CAPACITY480100For the best overall efficiency, chooseIR’s patented Auto Control Select (ACS)system. ACS constantly monitors thecompressor’s operation and automaticallyadjusts the control system to the modethat best suits your system’s needs:On-line/Off-line or Upper Range Modulation.

SSR: Unparalleled ReliabilityAdvanced Airend DesignOur time-proven integral gear drive is the onlymaintenance-free drive system in the industry.The airend and motor are permanentlyaligned, so during the course of normaloperation no adjustments are ever required.At the core of the SSR is our ruggedand reliable airend. Used in thousandsof compressors worldwide, our airendis known for trouble-free operation andminimal maintenance.The drive train is totally enclosed so that nodust or dirt can get in, and our triple-lip shaftseal prevents leakage of coolant to the motor.Our airends utilize only the highest qualityduplex tapered roller bearings. Roller bearingsprovide line contact for thrust loads, anddramatically improve the life of the airend.The SSR airend also incorporates a bearingcoolant dam that traps coolant in the bearingduring shutdown. This ensures proper bearinglubrication during the critical start-up phase,and a longer bearing life.Energy Efficient MotorEvery SSR compressor incorporates adurable high efficiency motor. SSR motorsoperate at peak efficiency under full loadconditions, ensuring maximum energy savings.I-R High Efficiency Motor Design Point10095Percent Efficiency908580"Off the Shelf"Competitive MotorDesign Point75Applied Point70100105110115Percent Load1201255

Reduced Bearing LoadsA lower compression ratio in each stagereduces bearing loads and increases airendlife. Our use of the highest quality bearingsavailable assures you of years of reliable,efficient service.Energy Efficient AirendIf you’re looking for the greatest efficiencypossible from a rotary screw then check outour two-stage compressors. The heart ofthe compressor is our time-proven two-stageairend. By compressing the air in two stepsinstead of one, energy savings of up to 15%are realized.Energy Cost/YearOur rotors are precision machined in atwenty-step process, ensuring unmatchedrotor profile accuracy, repeatability, andefficiency.Coolant CurtainOne of the keys to the efficiency ofthe two-stage is the coolant curtain.Significant cooling of the air is achievedby injecting atomized oil into thecompressed air stream leaving thefirst stage. Lowering the airtemperature prior to entering thesecond stage significantly lowersthe energy required for compression.The coolant curtain also eliminatesthe need for an intercooler.Single-Stage15%Energy SavingsTwo-Stage0200040006000Operating Hours/Year68000

SSR AIR-COOLED PACKAGE (FRONT VIEW)The SSR PackageEnd-to-End CoolingTo fit the needs of your compressed airsystem, we offer you the choice of anair-cooled or water-cooled design.The aftercooler is located at the inlet end ofthe package. This allows cool compressedair only 15 F/8 C above the ambienttemperature to pass downstream to theair system.115 F/46 C AmbientSSR compressors operate in high ambientconditions, making them suitable for locationsaround the world. Even if the compressor isnot operated in sweltering climates, the hightemperature rating ensures fewer nuisanceshutdowns caused by fouled coolers.Star-Delta StarterInherent Leak-Free DesignBy using SAE O-ring fittings on all connections1/4" and larger, we’ve significantly reducedpotential leakage problems associated withconventional threaded connections.8This advanced starter gives the compressora controlled, cushioned start, eliminatingcurrent surges and extending componentlife for increased system reliability.

SSR AIR-COOLED PACKAGE (BACK VIEW)8000 Hour/2-Year LubricantRugged MotorUltraCoolant reduces maintenance costsby going longer between changes. Also,because of UltraCoolant’s superior separatingproperties, less coolant is passed downstream to the air system, further minimizingcoolant costs.The extra toughness built into the SSR motormeans it will run when other motors quit.Maintenance and repair of the SSR motorare just like any other motor you own.Quiet EnclosureA low sound enclosure is standard and keepssound levels to a minimum.Every SSR compressor undergoes state-ofthe-art computerized testing to ensure thatyou get the best possible performance undervarying conditions.Easy ServiceabilityEasy ConnectivityThe SSR package is remarkably uncluttered,making servicing easy. All components arereadily accessible behind easily removablepanels.The SSR is fully piped and wired, resulting insimple external connection of all utilities.Factory-TestedConvenient Top ExhaustThe cooling air flow discharges from the topof the package facilitating easy ducting forremoval and/or recovery of exhaust heat.9
