Dual-tower desiccant dryers for the continuous dynamic adsorption of water vapor from compressed air. Using pressure swing adsorption technology (PSA)*, air gets dried under pressure by passing through one desiccant bed while the other bed is being regenerated.
Regeneration of the wet desiccant is accomplished without the use of heat. A small portion of the dried process air, called purge, is passed through the wet desiccant bed at near atmospheric pressure. This super-dry air strips the desiccant of all previously adsorbed water vapor.

Fully assembled, packaged unit comes complete with desiccant.
✓ Ready for operation Regeneration purge flow is counter-
current to the direction of air flow during drying.
✓ Maximum removal of moisture and lowest dew point assured during the adsorption process
Prevents line surges and minimizes desiccant attrition.
✓ Controlled repressurization
Compressed air continues to flow through during power and/or pilot air failure.
✓ Fail-safe design
A moisture indicator is provided.
✓ Continuous visual color indication or display
All functions are performed automatically by a PLC.
✓ PSA* fixed 10-minute cycle High-performance activated alumina desiccant.
✓ High surface/volume ratio provides maximum adsorption
Universal 110/240V power supply.
✓ Low power requirement
Coalescing pre-filter and particulate after-filter with DPIs and drains, mounted and pre-piped on most models, supplied loose on others.
✓ Xebec’s filters are best-in-class, ISO/CRN certified
