Incorporating high-quality components, PH heatless adsorption dryers provide you with clean,
dry air to extend the life of your equipment and products. Heatless adsorption dryers use dry,
expanded purge air to remove moisture from the desiccant material. PH 55-550 HE adsorption
dryers are available in 3 PDP variants: -20°C/-4°F , -40C°/-40°F and -70°C/-94°F, each optimized
to provide the lowest purge loss. The unique manifold (patent pending) includes pilot air
controlled 3/2-way valves, which switch fast and reliably.
The pressure drop over the valves is reduced to a minimum.
This does not only result in a low pressure drop over the dryer, but also ensures maximum purge
air expansion during regeneration. The latter makes that the purge consumption of the dryers has
been reduced significantly. The desiccant is spring-loaded and housed in a robust extruded
aluminum body, which can operate up to 14 barg/203 psig (fatigue load). The dryers are equipped
with a mounted pre-filter and after-filter as standard and can also be wall-mounted with a
specially designed wall-mounting kit (optional). Operating costs are optimized at all times
thanks to the availability of compressor synchronization and purge nozzle optimization as
standard and PDP control as option. The full machine status can be checked on the display of
the controller and the vessel pressure gauges on the unit. The controller indicates whether power
supply is connected, towers are pressurized, valves are functioning properly or preventive
maintenance needs to be done. In case the optional PDP control is connected, the PDP value
 can monitored from the display. Alarms and warnings can also be triggered remote with the
available voltage-free contacts. Optionally the PurelogicTM can be used as central brain
of the adsorption dryer.
