Atlas Copco Pneumatech PB Blower Purge Desiccant Compressed Air Dryer

Atlas Copco Pneumatech PB series blower purge desiccant air dryers deliver dependable sub-zero pressure dew points for critical industrial processes that require ultra-dry compressed air.

Compressed air discharged from standard plant compressors contains moisture vapour that condenses into liquid water inside distribution pipelines, causing rust formation, control valve freezing, and batch product contamination.

The Pneumatech PB dryer features an engineered twin tower design loaded with premium activated alumina or molecular sieve desiccant beads to adsorb water vapour directly at pipeline pressure. While one vessel actively dries the compressed air stream down to a stable minus forty degrees Celsius pressure dew point, the offline vessel undergoes thermal regeneration.

• Blower purge regeneration: An integrated centrifugal blower and high efficiency electric heater pull ambient air for regeneration, eliminating the costly compressed air purge loss typical of heatless desiccant systems.
• Dew point dependent switching: Monitors desiccant bed saturation and delays tower changeover until drying capacity is fully utilized, delivering substantial energy savings under partial load conditions.
• Heavy duty valve and silencing package: Heavy duty switching valves, reliable non-return check valves, and acoustic silencers ensure smooth, low-noise depressurization and repressurization without creating downstream pressure shocks.
• Digital electronic controller: Provides continuous monitoring of tower switching sequences, heating and cooling temperature curves, operating alarms, and real-time dew point trends.
• Export-grade protection: Standard factory export packaging and heavy duty wooden pallet crating protect structural vessels, electrical cabinets, and desiccant charges from transit shocks and environmental humidity.
