PB dryers use heated blower purge air to remove moisture from the desiccant material and have therefore no purge loss during regeneration.
PB Series Zero Purge Desiccant Dryers reduce life cycle cost even further by also eliminating purge loss during cooling.
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 costs even further by also eliminating purge loss during cooling. 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. 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.
