Pneumatech Adsorption dryers with zero-purge  with cooling in closed loop

 

PB 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 capable of 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 bar/ 210 psi (fatigue load).
All dryers are standard equipped with 2 coalescing pre-filters
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.
