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.
The PurelogicTM offers impressive control and monitoring
capabilities, and can communicate with industrial protocols as
Modbus, Profibus or Ethernet/IP.
