Revision 7/28/0
The ARID-X10C dryer is a fully portable dryer
designed to dry hygroscopic resins quickly and
efficiently. It is ideal for insert molders and
laboritory applications, or where production rates
are 10 lbs./hr or less.
The ARID-X10C dryer is available in 110 volt and
230 volt models. The power requirements for the
110 volt model are a voltage range of 10 -130v
AC at 0/60 Hz., single phase with a 20 amp current
rating and the 230 volt model requires a range 220-
2 0v AC at 0/60 Hz., single phase with a 10 amp
current rating.
Regenera ion Cycle
The ARID-X10 utilizes our HP4-X dual desiccant
bed design that provides a constant supply of dry
air to the material hopper. While one bed is
removing moisture from the process air stream, the
other bed is being regenerated. The entire process
is controlled by an ELC factory programmed with
the tower heat-up and cool down times required to
regenerate the desiccant. When the regenerated
bed completes this cycle, the zone valve switches
the air stream and the newly regenerated bed is now
used for drying the process air. The saturated bed
is then regenerated, repeating the cycle. Please see
the Regeneration Cycle Diagram on page 8.
The airflow design of the ARID-X/HP4-X dryers
makes the regeneration cycle more efficient
because we utilize a small amount of the
desiccated process air, rather than ambient air, to
regenerate the desiccant bed. This reduces the
impact of the high moisture content of the
ambient air, which would contaminate the
desiccant bed, and allows the dryer to attain a
lower dew point. This cycle is depicted in the
schematic on page 8.
HP4-X Design
Our patented HP4-X design incorporates 4
desiccant beds where two are stacked, one over
the other in each tower. This nearly doubles the

Revision 7/28/0
amount of desiccant available for drying the
process air stream, and because of the tower
design, the dryer is able to regenerate the
desiccant in the same time as our ARID-X series.
This allows the dryer to operate in very high
humidity conditions without affecting the process
air dew point. In fact, this design produces dew
point levels of –40° to -80° C for faster more
complete drying of your material. Please see
Airflow diagram on page 7.
Ma erial Hopper Requiremen s
The Arid-X10 dryer can be used with any
material hopper that is designed to allow proper
air flow. Hoppers that are equipped with a
material spreader cone and diffuser basket will
provide the best performance. To obtain optimal
drying performance, we recommend that you
utilize our uniquely designed material hoppers.
Dri-Air’s “all stainless” hopper design utilizes a
stainless steel inner shell surrounded by a
stainless steel jacketed insulation layer. The
easily removable stainless steel spreader cone/
diffuser basket assembly promotes proper
material flow to ensure that the material is dried
efficiently and no undried material is left at the
hopper bottom that needs to be fed out prior to
operating. You must ensure that your hopper is
kept filled, to ensure that you have sufficient time
to dry the material.
Dryer Con rols
The Arid-X10 dryer is supplied with a factory
programmed ELC Control Module and a Digital
Temperature Controller.
ELC Control Module
The ELC Control Module controls the
regeneration cycle described in the previous
section. It has been factory programmed and
does not require any additional input by the
DRYER DESCRIPTION

Revision 7/28/0
operator. The module will automatically monitor
and control the dryer’s operating parameters by
timing the regeneration cycle as well as
monitoring and controlling the regeneration
heaters and dryer alarms.
Digital Temperature Controller
The Digital Controller works in tandem with the
ELC Control module to monitor and control the
process air temperature. The controller’s touch
pad allows the operator to input the dryer’s
process air temperature settings and alarm points.
These are explained in more detail later in this
manual.
Dri-Air Elec ric Ro ary Zone Valve
The Arid-X10 utilizes our exclusive electric
rotary valve technology, which helps make this
dryer truely portable and low maintenance. As
the valve does not need compressed air to
operate, it is far more reliable than valves that
depend on clean compressed air at a constant
pressure.
The valve is designed to be practically
maintenance free, as the seals are self seating and
are designed to provide years of trouble free
service. The electric controls are easily
accessable for trouble-shooting, and are equipped
with lights to indicate the zone position of the
valve.
