Air Compressor Life Cycle Costs

According to Best Practices forCompressed Air Systems,Compressed Air Challenge, SecondEdition, 2007, energy costs now

represent 82% of the total operatingexpenses. Energy savings fromSullair’s Two-Stage Compressors cansignificantly reduce life cycle costs.

Sullair’s two-stage compressorssignificantly reduce operating andenergy costs over the entirecompressor life cycle. Contributing tothe energy savings are:

• Sullair’s proven air end with the lowrestriction inlet valve

• High efficiency fan

• Low pressure drop air-fluid separationsystem to prevent energy loss

Sullair designs deliver cost savings forthe life of the product. Improved airfiltration translates into:

• Extended separator life

• Improved fluid filter life

• Less lubricant contamination

To reduce fluid disposal costs, weoffer our biodegradable Sullube™

8000-hour fluid, or 24KT™, a long-lifefluid that never needs changing.

Two-stage compressors* have apower advantage of 11 percent to13 percent over equivalent sizedsingle-stage compressors for twokey reasons:

Compression is Divided BetweentheTwo Stages

In a single-stage compressoroperating at 100 psig at sea level,the compression ratio is 7.9 to 1 (inabsolute terms). A two-stagecompressor operating at the samepressure will have a compressionratio of 2.8 to 1 in each stage (2.8is the square root of 7.9) achievingthe compressor’s power savings.

Internal Leakage Losses areReduced

Reduced pressure differenceacross each stage facilitatesreduction in leakage losses.

Sullair’s Superior End-to-EndDesign

Sullair’s TS two-stage tandemcompressors use two sets of rotorsarranged in a unique end-to-enddesign that achieve higherefficiencies than other two-stagerotor arrangements. This design isbased on Sullair’s proventechnology used in its single-stageunits, which has set the standardsfor efficiency and reliability insingle-stage compressors for morethan four decades.

The industry standard since itsintroduction in 1984, the TS Seriestandem compressors offerunmatched full-load efficiency;often providing a two-year paybackin energy savings compared withsingle-stage compressors. With thetandem’s variable capacity control,featuring spiral valve technology,

further operating efficiencies canbe achieved during part-loadoperation.

Rotary Screw Reliability

These TS models use a two-stagerotary screw air end, featuringSullair’s rugged bearing design:tapered roller bearings on thedischarge end and cylindrical rollerbearings on the inlet for high loadcarrying capacity.

Extended Bearing Life

By dividing the compression ratioacross two stages, the two-stagetandem will significantly exceed thelife of the average single-stagecompressor.

Decades of Proven Reliability areTestimony to the Quality of theSullair Air End

Although the principle of rotary screwcompression remains the same, Sullairis continually improving materials,engineering and design of its air endsand compressor packages.

No Loss of Capacity or Efficiency

Sullair air ends have only two movingparts: the asymmetrical profile rotors.Contact occurs only on a lubricatedpitchline, so wear is virtually eliminated.As a result, Sullair compressors do notlose capacity or efficiency.

Longer Air End Life

Controlled pressure lubrication andBearing Fluid Reservoirs (BFR) assurea reliable supply of fluid to rotatingelements.

Lower Operating Costs

Discharge port matches ratios ofvolume and operating pressure formaximum efficiency. Axial air inletavoids preheating inlet air for furthersavings.

It’s a fact: the electric power cost torun an air compressor continuously forone year is often two to three timesgreater than the purchase price of thecompressor itself.

That’s why Sullair developed the two-stage tandem compressor. Bycombining two-stage compressionand a spiral valve, the TS performswith unmatched full-load and part-load efficiency and often providesa two-year payback in energy savingscompared to a single-stagecompressor.

Energy Savings Built In

Sullair two-stage tandem compressorshave been proven to be 13% moreefficient than single-stage screwcompressors at full-load operation.At 60% load, the Sullair two-stagetandems provide up to 30% savingsover single-stage compressors.

How ItWorks

The compression volume varies to suitthe air demand by progressivelyopening or closing internal bypassports on the air end.

Capacity is matched to systemdemand, reducing cycling time andextending component life.

Part-load capacity and efficiencycan produce energy savings up to17%.

Variable Capacity Control SavesYouPower

The compressor displacement ismatched to the output need. TheVCC technology assures precisionoperation for virtually any part loadpoint. It provides significant powersavings at part load conditions,compared to compressors usingsuction throttling, or load/no loadcontrol.

Increases Capacity ControlEfficiency

By activating automatically when theunit is operating under partial load,and allowing the compression of onlythe required quantity of air, the spiralvalve increases the efficiency of thecompression process. The ultimateresult is greater compressionefficiency and reduced powerconsumption.
