    lem Water jeopardizes everything you want yourcompressed air system to do. It ruins product andfouls processes. Heres how: In addition to water, compressed air can also contain dirt, wear particles, bacteria and lubricating fluid.

    Sludge blocks valves and orifices, causing high maintenance and costly air leaks.

    How much water is too much?Any amount of water is too much.

    Relative humidity is the amount of water vapor in air relative to what it could

    hold at a given temperature.

    Moisture in compressed air remains in a vapor state through the compression

    cycle, so it is not a problem until it leaves the compressor.

    Air discharged from a compressor is approximately 150F to 450F.

    At 75F and 75% relative humidity, a 75 HP compressor takes in 46 gallons of

    water vapor in 24 hours. When this air is cooled to approximately 35F at 100

    psig, the water vapor condenses into 46 gallons of liquid!

    The importance of clean, drycompressed air.

    Water mixes with thesepollutants to form an

    unwanted abrasive sludge.

    This sludge, often acidic,rapidly wears tools andpneumatic equipment.

    Sludge corrodes pipingand can foul product and

    air-operated devices.

  • Sullair Desiccant Dryers provide clean, dry air byremoving the water. The result: corrosion and damage are eliminated.

    Productivity improves and maintenance costs are reduced.

    The service life of air tools, motors and cylinders is extended.

    The life of your entire compressed air system is prolonged.

    Eliminates freezing in outdoor compressed air lines.

    Eliminates corrosion in compressed air lines.

    Reduction or even elimination of bacterial growth.

    The benefits of Sullair Regenerative Desiccant Dryers:

    Clean, dry compressed airSullair desiccant air dryers use a bed of high quality activated alumina desiccant toadsorb water from compressed air providing a continuous dewpoint as low as -40F (standard) or -100F (optional). While one tower is drying the air the other isbeing regenerated. The dryer operates continually and automatically with nointerruption of flow and no dewpoint spikes.

    Reliable operation.Conservative design limits, high quality valves, fail safe controls and attention to

    detail assure long, trouble-free service life.

    Clean, dry compressed air is essential to your production or process.

    Sullair SD dryers use activatedalumina desiccant to adsorb watervapor from compressed air. Bycombining the proven benefits ofdesiccant drying with the mostadvanced designs, Sullair offers anextremely compact, reliable system toclean and dry compressed air for themost critical applications.

    Easy InstallationSullair dryers are prepackagedrequiring only air inlet/outlet andsingle point power connections. Sullairrecommends the use of a SullairMPH/PH coalescing pre-filter toensure long desiccant life and MPR/PRparticulate after-filter to catch anydesiccant dust.

    Wide Range of OperatingConditionsThe Sullair SD dryers can operate withinlet temperatures from 80F to 120F,inlet pressures from 80 to 140 psig andflows from 100 to 3400 scfm. Theycan be sized to provide either a -40For -100F outlet pressure dewpoint.

    Market Leading Design Towers are built in accordance with

    ASME Section VIII Div 1. Desiccant is a high quality activated

    alumina with high adsorption andabrasion resistance.

    Towers and piping are shot blastedand then protected with an anti-corrosive acrylic polyurethane.

    Depressurization mufflers offerreduced noise levels

    High strength nylon control linesfeed filtered control air to highquality solenoids. (Copper orstainless steel optional.)

    Heavy duty inlet and exhaust valveshave stainless steel internals andTeflon valve seats for reliability andlong service life.

    Repressurization circuit for smoothchange over and long desiccant life.

    Options Dewpoint Dependent Switching

    (DDS). If the hygrometer sensesthat there is moisture-adsorptioncapacity available in the on-linedesiccant bed before the towerreaches the end of its cycle, a signalis sent to the controller to delay thechangeover and utilize the sparedesiccant capacity. Dryers withDDS can achieve energy savingsfrom 30% to as much as 80%.
