PB 850-3400 Series Blower Purge Desiccant Air Dryer

PB dryers are for customers who focus on energy efficiency and low lifecycle costs, while maintaining the highest standards in air purity. Pneumatech extends its PB dryer range to flows up to 10800 m³/hr with both blower purge and Zero Purge variants.

PB dryers use heated blower purge air to remove moisture from the desiccant material and have therefore no purge loss during regeneration. The cooling phase happens in a closed loop, hereby minimizing the performance impact at high ambient temperature and relative humidity.

Operating costs are reduced to the absolute minimum thanks to PDP control, regeneration & cooling temperature control and compressor synchronization; which are all integrated in the Purelogic™ controller. The Purelogic™ also ensures maximum reliability by monitoring the most important parameters of the dryer and offers impressive control and monitoring capabilities.
