PB Zero Purge dryers have the absolute lowest lifecycle costs, by eliminating purge losses during regeneration and cooling.
dryers are for customers who focus on energy efficiency and low lifecycle costs, while maintaining the highest standards in air purity. PB
dryers use heated blower purge air to remove moisture from the desiccant material and have therefore no purge loss during regeneration. The
Zero Purge variants reduce life cycle cost even further by also eliminating purge loss during cooling. PB 210-635 HE adsorption dryers are
drying air to a PDP of -40°C/-40°F as standard and -70°C/-94°F as option for purge units.
The desiccant is housed in welded vessels, which are coated and can operate up to 14.5 barg/ 210 psig (fatigue load). All dryers are standard equipped with 2 coalescing prefilters before and 1 particulate filter after the dryer. 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. Zero Purge variants are equipped with a purge back-up mode which switches the dryer to purge cooling mode in case PDP could not be met at ambient conditions outside of limitations. The Purelogic™ also ensures maximum reliability by monitoring the most important parameters of the dryer and offers impressive control and monitoring capabilities.
