Chapter 2: Functional Description
2-1 Models Covered in This Manual
This manual provides instructions for installing and operating your 5, 10 or 15 cfm
compressed air dryer
2-2 General Description
Mini compressed air dryers are designed to generate heated, dehumidified air at carefully
controlled temperatures for use in plastic drying systems. Drying systems are sized to meet
specific requirements stated by the purchaser at the time of purchase.
Moisture removal from hygroscopic (moisture attracting) plastic pellets is an essential step
in the manufacture of high-quality plastic products. This dehumidifying dryer is used to
generate very low dew point air, heated to a controlled temperature for drying plastic
pellets and regrind.
Many variables were considered in the selection of your drying system, including type of
materials, residence time, throughput of the extruder or injection molding machine. Should
your operating environment change, the manufacturer can advise you on necessary
equipment and process time and temperature modifications required for your system.
2-3 Typical Features and Components
•Electrical solenoid valve
•Compressed air filter, regulator, and gauge
•Drying temperature range of 120ºF to 400ºF
•Display of process temperature set point and actual settings

2-5 Safety Features
This section includes information on safety devices and procedures that are inherent to the
10 cfm compressed air dryer. This manual is not intended to supersede or alter safety
standards established by the user of this equipment. Instead, the material contained in this
section is recommended to supplement these procedures in order to provide a safer
working environment.
Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel
from dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to
the design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and the Joint Industrial Council (JIC) are just a few of the
organizations that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the dryer;
however, it is the responsibility of the personnel operating and maintaining the equipment
to familiarize themselves with the safety procedures and the proper use of any safety
devices.
High Temperature Safety System
A high temperature safety system will disable the dryer if the process temperature is too
hot. The high temperature safety is designed so that if it fails, the failure causes a “safe”
condition, and the dryer will not run. The compressed air continues flowing to cool down
the system.
Airflow monitoring Safety System
If the airflow source to the compressed air dryer is below 35 PSI, the unit will shut down and
not run. This is an indication that there is not enough pressure and flow for proper
operation of the unit.

Compressed Air Dryer 882.03168.00 2/13/2023 14
Line Cord Plug (115/1/60 units only)
The line cord plug allows the operator or maintenance personnel to unplug the dryer from
its power source and tag it out. This plug may be tagged with any number of approved
electrical lockout tags. These tags are available at most electrical supply stores. Always
disconnect power before servicing or moving this unit.
DANGER! At no time should anyone remove the lockout or reconnect the twist plug,
other than the person who installed the lockout or who unplugged the
twist plug.
2-6 Drying Hopper Air Trap
Refer to the drying hopper Operation and Installation manual for proper operation of the
drying hopper.

Compressed Air Dryer 882.03168.00 2/13/2023 15
2-7 Remote Membrane Dryer for Low-Dew point Operation
(Optional)
Membrane dryers take a small percentage of the dried gas and direct it back in a sweeping
pattern through the module shell. This provides a driving force to remove the moisture with
the minimum purge required.
The moisture vent membrane dryer consists of thousands of hollow-fiber membranes made
of tough temperature and pressure-resistant plastic. The inside surface of these hollow
fibers is coated with an ultra-thin layer of a second plastic that actually separates the water
vapor from the air. This second coating allows air to pass through it over 20,000 times easier
than it allows water to pass. As a result, moisture is expelled rapidly with very little air loss.
Two-stage drying provides the option of using the moisture vent directly at the point-of-use
in combination with refrigerated air dryer.
As a single stage unit, the dryer provides consistent performance from 60ºF to –20ºF outlet
dew point. When combined with a refrigerated air dryer, the moisture vent system will
suppress or reduce the inlet pressure dew point to below –40ºF with very low sweep
requirements.

2-8 Microprocessor Controls
The compressed air dryer uses a microprocessor-based PID temperature controller for
maintaining process air temperature. The controller is a modular, self-contained unit that
you can remove from the mounting housing. All parameters except for the process air set
point are factory set and adjusted. Normally, no field adjustment to the internal controls is
necessary.

Chapter 3: Installation
3-1 Uncrating the Equipment
The compressed air dryer has a handle at the top of the cabinet to use for lifting. For
hopper-mount configurations, be sure to support the hopper when lifting and placing the
dryer. Use caution and observe safety rules when lifting and placing your dryer. Be sure it is
securely attached and additional bracing is used if necessary.
3-2 Connecting a Hopper-Mount Dryer to a Hopper
When mounting the dryer to an existing hopper, use the adapter and the self-tapping
screws that are provided with the unit to mount the dryer to the inlet of the hopper. The
adapter is pre-drilled with three holes that are used to mount it to the hopper.
Note: In some cases, depending on the drying hopper model, an adapter may not be
required. If an adapter is not required, attach the dryer to the hopper with the
clamps provided, and install the exhaust filter to the drying hopper
outlet/return line.
Use the following procedure to mount the dryer to a hopper using an adapter (See Figure 3):
1. Mark the holes in the inlet tube of the hopper for drilling.
2. Use a 9/64” drill bit to pre-drill for the #8-32 screws that are provided.
3. Spread silicone adhesive over the area where the adapter will mount to the hopper inlet
tubing.
4. Place the adapter onto the tubing and install the three screws to hold it in place. Allow
sufficient time for the silicone to cure before you operate the dryer.
5. Attach the dryer to the hopper with the clamps provided.
6. Install an exhaust filter to the drying hopper outlet/return line.
Figure 3: Typical Hopper-Mount Configuration

Compressed Air Dryer 882.03168.00 2/13/2023 18
3-3 Connecting a Floor-Mount Dryer to a Hopper (Optional)
Use high-temperature flexible dryer hose or rigid tubing to connect the dryer to the drying
hopper. Keep the delivery hose to the drying hopper as short as possible to minimize heat
loss. We strongly recommend insulated hose for maximum energy savings. Make sure that
hoses are not kinked or collapsed.
Use the following procedure to connect a floor-mount dryer to a hopper:
0. Using the clamps provided, clamp a hose adaptor onto the dryer and the hopper.
(See Figure 4.)
Note: Depending on the drying hopper model, the clamp and hose adapter may
not be required. Connect the dryer hose with the hose clamp directly to the process
air inlet of the drying hopper.
1. Install an exhaust filter to the drying hopper outlet/return line.
2. Drying hopper air inlet and outlet locations vary, but always connect hoses so the
dry process air from the dryer enters the bottom of the drying hopper and flows out
the top.
Figure 4: Floor-Mount Configuration

Compressed Air Dryer 882.03168.00 2/13/2023 19
3-4 Making Electrical Connections
The serial tag lists voltage, phase, and amp draw information. Line voltage must be within
plus or minus ten percent of the voltage listed on the serial tag, or damage may occur.
Never supply any voltage other than what the dryer is configured for.
Fulfill all national, state, and local safety and electrical code requirements. A qualified
electrician should make all electrical connections.
Connect main power to the dryer. Install a fused disconnect with a lockout feature in the
power main leading to the dryer. The power drop must include a ground wire. Make sure all
electrical connections are tight.
Note: Due to variances in 220-240 V connections, customers must supply the plug for
these dryer models.
3-5 Making Compressed Air Connections
The compressed air supply must be regulated to 80 PSI (5.5 bars). Low air pressure will
create poor drying performance. If the pressure in the system drops below 35 PSI, the alarm
light will activate and the process heater and solenoid valve will shut off.
Note: For maximum drying efficiency, we recommend a refrigerated compressed air
connection. Not using refrigerated compressed air (to provide pre-conditioned
compressed air to this unit) will affect drying performance and material drying
capabilities.
To achieve the lowest possible dew points, an optional remote-mount membrane dryer
assembly is available. See Section Error! Reference source not found. on page Error!
Bookmark not defined. for more information about the remote-mount membrane dryer
assembly.
Connect a minimum of 3/8” (9 mm) air line to the top of the filter regulator. Compressed air
must be clean, dry, and free of oil. A shut-off is recommended for your in-plant air supply.
In-line filters can handle small amounts of moisture; in-line desiccant filters or packed beds
of granular absorbing polymer can remove oil mist and condensed oil.

Compressed Air Dryer 882.03168.00 2/13/2023 20
3-6 Installing the Remote-Mount Membrane Dryer (Optional)
The membrane drying kit can be mounted anywhere near the compressed air dryer. The kit
is pre-assembled with a bracket that can be mounted to any flat surface with two screws.
Use Figure 5 as a reference for this installation.
1. Remove the large particle filter, including the close nipple, from the inlet of the
compressed air dryer.
2. Attach the large particle filter (including the close nipple) to the membrane drying kit.
Note: The membrane drying kit must have the large particle and the coalescing
filters in place and functioning properly to ensure full drying capabilities of the
membrane. Both filters must be checked and cleaned regularly.
3. Attach the 1/4” NPT elbow to the inlet of the compressed air dryer.
4. Run the 3/8” hose between the outlet of the membrane drying kit and the inlet of
the compressed air dryer. Use thread sealant on all threaded connections.
