3 Dry Air Systems, Inc. Holds the key for clean, dry air systems

4 Compressed air contains: Water Contaminants Left unprotected –W–Water (temperature) –C–Contaminants (oil)

5 The problems: All air systems trap and contain water moistureAll air systems trap and contain water moisture Water and contaminants harm:Water and contaminants harm: –pneumatic controls performance –their life expectancy –reservoir capacities –affects air compressor duty cycles

6 Typical Offerings Include ChillersChillers –expensive to operate –labor intensive to install –limited efficiencies –space robbers

7 Smaller Offerings Water separatorsWater separators –ineffective –limited capabilities –no dew point

8 Today's Offerings Current desiccant dryersCurrent desiccant dryers –difficult to maintain –limited filtering capabilities –short service intervals –cannibalizes excessive air for regeneration

9 ImprovesImproves system reliability PneumaticPneumatic controls protection IncreasedIncreased life expectancy FullFull reservoir capacities ExpansionExpansion flexibility CompactCompact sizes QualityQuality of workmanship Dry Air Systems Offers:

10 Benefits To Air Quality Filters to 15 SCFM.2 of 1% Regen Clean Dry Continuous molecular sieve regeneration -40 Pressure dew point depression Continuous air flow Built-in moisture indicator (optional)

11 Identifying the Units Components Air dryers (2 min.) Mounting bracket Inlet, outlet, purge & control ports MLT valve or PLC Safety valves Mufflers Moisture indicator (opt.)
