NextGen TW Series Heatless Desiccant Air Dryers
Parker NextGen TW Series Heatless Desiccant Air Dryers remove water vapor from compressed air through a process known as Pressure Swing Adsorption. A standard pressure dewpoint of -40°F (-40°C) is attained by directing the flow of saturated compressed air over a bed of desiccant. The desiccant bed is regenerated by using dry purge air from the system.

The NextGen TW Series is the simplest desiccant air dryer in our offering, the dryer uses heatless pressure swing adsorption for drying the compressed air to -40°F PDP. The pressure swings between a left and a right tower typically on a cycle of 5 to 10 minutes. During regeneration, a percentage of the dry compressed air is used for purge, this helps regenerate the fully adsorbed desiccant.
Features & Benefits of Parker NextGen TW Series Air Dryers:
Basic Controller
• Allen Bradley® PLC
• Compressor demand via external dry contact (CycleLoc®)
• Selectable cycle settings
• Manual Stepping
PowerLoc® Energy Management System
Energy savings of up to 80% can be achieved with the proven PowerLoc® energy management system. Regeneration requirements are dependent on flow, pressure and temperature. The PowerLoc® system allows the cost of drying compressed air to be matched exactly to your plant conditions. PowerLoc® controls the drying cycle by continuously reacting to the loading under which the dryer is operating and minimizes the energy input required. As dryers rarely operate at full rated capacity all of the time (eg. during shift work and periods of low demand), this energy management system can provide considerable savings.
Sizing and Model Selection
To ensure quoted air purity performance is met, a compressed air dryer must be sized correctly for minimum operating pressure, maximum inlet temperature and maximum inlet flow rate using the Product Information Sheet
