ZEKS Eclipse™ ZPB Heatless Desiccant Dryers are designed to
adsorb moisture from compressed air. The dryers are constructed
with two towers, each containing desiccant beads, that alternate
between online (drying) and o
ffl
ine (regenerating) modes,
yielding a continuous stream of dry air at the dryer’s outlet.
During normal operation, wet air passes through the online
tower and water vapor from the air is adsorbed (collected) on the
desiccant beads. While air is being adsorbed in the online tower,
the moisture on the desiccant in the o
ffl
ine tower is removed by
a process called desorption (regeneration). After an initial rapid
depressurization, a portion of dried air from the online tower
passes over the desiccant bed and carries the moisture o
ff
the
bed and out the dryer’s exhaust.
The continuous, alternating process of adsorption and desorption
is controlled using a timer that switches the towers in a speci
fi
c
timed sequence. Very dry compressed air dew points are
achieved through the continuous switching and operation of this
dryer. ZEKS o
ff
ers dryers to provide either -40°F, -80°F or -100°F
pressure dew point outlet air.
