What is the Carousel Plus W Series
Dryer?

The Carousel Plus W Series dehumidifying dryer produces hot, low-dewpoint air
that removes moisture from hygroscopic plastics. The dryer pulls warm, moist air
from a drying hopper and circulates it through a dehumidifying desiccant wheel.
The dryer then heats the air to the drying temperature you selected and circulates it
through the material in the hopper.

The dryer’s closed-loop design ensures a continuous supply of hot, dehumidified
air while preventing contamination from moisture in the plant.

Typical Applications

1 Dryer on the floor; hopper on the throat.

2 Hopper on a floor stand; the dryer next to it.

3 Dryer and hopper on a mobile floor stand (MDC version 150 and 200 only).

4 Central dryer, with ResinWorks system.

The W Series Dryer can be used successfully in applications that require:

• A contamination-free drying environment.

• Drying temperatures within the ranges shown in the following table:

Typical Applications (continued)

Model Drying Temperature Range

Low temperature (with precooler)* 100° - 150°F {38° - 66°C}

Standard 150° - 240°F {66° - 116°C}

High heat (with aftercooler)* 150° - 375°F {66° - 191°C}

Low-high (with aftercooler & precooler)* 100° - 375°F {38° - 191°C}

* See page 3-13 and Appendix B and C.

• Throughput rates of 150 to 400 lbs {68.1 to 149.2 kg} per hour (some

materials can be run at a higher rate).

• Dewpoints of -40°F {-40°C}.

Use the aftercooler when:

• You are drying at temperatures over 240°F {116°C}.

• Throughput rates are less than 50% of the dryer’s rated capacity.

• You are pre-drying material at temperatures over 150°F {66°C}

Standard Dryer Features

• Dewpoint monitor / dewpoint control

• Audible and visual alarm

• Temperature setback

MDC Options (models 150 & 200 only)

• Non dry air conveying

• Machine loading only

• Self loading (machine and hopper loading)

When supplied for
central drying appli­cations, the W series
dryer is not equipped
with a process heater.
Therefore, as a cen­tral dryer, the W
dryer will only sup­ply dry air to the hop­pers.

THE

PROCESS (D

RYING) C

YCLE

The process blower pulls moist air from the top of the drying
hopper. The air passes through the process filter and aftercooler,
then into the desiccant wheel, where moisture is removed. The dry
air is delivered to the hopper (after it passes through the optional
precooler, if installed) where a spreader cone evenly distributes the
air through the material.

How It Works

The W dryer achieves continuous, closed loop drying by passing air simultaneous­ly through two heaters and a continuously rotating desiccant wheel.

THE PROCESS (DRYING) CYCLE

The process blower pulls moist air from the top of the drying hopper. The air
passes through the process filter and aftercooler into the desiccant wheel, where
moisture is removed. The now dry air moves through the optional precooler (if
installed) and process heater, where it is heated to the drying temperature selected
by the operator. The hot, dry air is delivered to the hopper where a spreader cone
evenly distributes the air through the material.

The Cooling Cycle

Regenerated desiccant must be cooled before it rotates back into the process cycle.
The process blower pushes a small amount of air through the cooling section of the
desiccant wheel. The cooling air then passes through the aftercooler and repeats
the circuit.

The Regeneration Cycle

The regeneration blower pulls air through the regeneration filter into the dryer’s
regeneration heater. The air is heated to 350° F {177° C} before it is pushed into
the “wet” section of the wheel. The hot air purges moisture from the desiccant. The
moist air is blown out the exhaust at the back of the dryer.

SPECIFICATION NOTES:

* The term SCFM stands for Standard Cubic Feet Per Minute, referenced to a pre-specified pressure, tempera-

ture and relative humidity. In most cases, SCFM is referenced to 14.7 PSIA 68° F and 36% relative humidity.
ACFM stands for Actual Cubic Feet Per Minute, and must be supplied with a temperature reference, due to the
change in air density with temperature. Because dryers operate at a relatively low pressure the effects on air den­sity are negligible.

† Dryers running at 50 HZ will have 17% less airflow, and a 17% reduction in material throughput.

Specifications may change without notice. Consult a Conair representative for the most current information.

• Volatile trap (only in conjunction with aftercooler) - The volatile trap is

recommended if drying materials that produce volitales that condense into a
waxy or oily residue and/or if the material contains excessive fines.

• Precooler - The precooler reduces the temperature of air flow after the desic-

cant wheel and before the process heater.

• Filter check - The Filter check sensor will activate a passive alarm when the

process filter is clogged or needs to be replaced.

• Heater current monitor - The heater current monitor measures the total

amperage across both the process and regeneration heaters and the pre-deter­mined power consumption values for the blowers and the control.

• CFM monitor - The CFM monitor measures the cubic feet per minute of air

flow across the inlet/outlet of the process blower.

• DeviceNet or SPI communications - Allows the dryer to be networked to

industrial control systems. DeviceNet communications are standard. Alternate
communications are available.

Preparing for Installation

The Carousel Plus W Series Dryer is easy to install if you plan the location and
prepare the mounting area properly.

1 Make sure the mounting area provides:

❒❒

A grounded power source supplying the voltage and correct current

for your dryer model. Check the dryer’s serial tag for the correct amps, volt­age, phase, and cycles. Field wiring should be completed by qualified person­nel to the planned location for the dryer. All electrical wiring should comply
with your region’s electrical codes.

❒❒

A source of water, if you have an aftercooler and/or optional

precooler. The W dryer’s aftercooler and optional precooler require 3

gals./min. {11.4 liters/min.} tower, city, or chiller water at temperatures of
45° to 85°F {7° to 29°C}. Pipe should be run to the planned dryer location.
Use flexible hose to connect the water pipes to the aftercooler and/or optional
precooler.

❒❒

Minimum clearance for safe operation and maintenance.

You should maintain 24 in. {61 cm} clearance on all sides of the dryer.

3-4 l Installation

Material and conveying lines

installed. If you plan to use

vacuum or compressed air

loaders to fill the hopper,

install conveying lines to the

drying hopper location.

✒

Positioning the Dryer on the Floor

1 Lift the dryer from the shipping container using a fork truck.

2 Position the dryer on the floor near the processing machine. Make sure the

location allows for the connection of all hoses.

Removing the Cable Tie from the
Desiccant Wheel

1 Open the dryer side panels and remove the cable tie securing the desiccant

wheel, if it was not done while unpacking the dryer.

Connecting the Main Power

CAUTION: Always disconnect and lock out the main power sources before making

electrical connections. Electrical connections should be made only by qualified personnel.

1 Open the dryer’s electrical enclosure. Turn the discon-

nect dial on the dryer door to the Off or “O” position.
Lock out the main power (see Page 1-6 for complete
lock out information). Turn the captive screw, and
swing the door open.

2

Insert the main power

wire through the knockout in the

side of the enclosure or the rear of the dryer. ( The
dryer’s electrical wire connection location was a factory
option and may be connected through the front or the
rear of the dryer.) Secure the wire with an appropriate
strain relief.

IMPORTANT: Always refer to the
wiring diagrams that came with
your dryer before making electrical
connections.

Connecting the Process RTD Probe

The process RTD probe monitors the temperature of the drying air as it enters the
hopper. If the probe is not installed correctly, temperature readings will be inaccurate.

1 Insert the probe at the inlet to the

hopper. The end of the probe must not
touch the walls of the inlet. The tip of the
probe should be approximately in the cen­ter of the tube. Tighten the compression fit­ting to lock the probe in place.

2 Plug the probe’s

cable into the
receptacle
labeled process
on the left side of
the electrical
enclosure. Hand

tighten the con­nector. Coil any
excess cable and
secure it with a
wire tie.

Connecting the Setback RTD

1 Insert the probe in the hopper outlet at the top of the hopper. The end of the

probe must not touch the walls of the inlet. The tip of the probe should be
approximately in the center of the tube. Tighten the compression fitting to lock
the probe in place.

2 Plug the probe’s cable into the receptacle labeled setback on the left side of

the electrical enclosure. Hand tighten the connector. Coil any excess cable
and secure it with a wire tie.

Process RTD

Setback RTD

When configured as
a central dryer, moni­toring the drying air
temperature is not
necessary since there
is no process heater
in the system.
Therefore, installa­tion and connection
of the RTD probe
and/or setback probe
is not applicable.

Checking for Proper Air Flow

This procedure is needed on W 150 - 400 models if the phase detection option was
not ordered with the dryer.

CAUTION: If the air flow direction is incorrect due to improper phase con­nection, material from the hopper can be pulled into the process heater,
causing permanent damage to this equipment.

1 Turn on the main power to the dryer. Make sure the dryer’s disconnect dial is

in the ON position. This powers up the control and the display lights will illu­minate.

2 Select the setpoint temperature by pressing the select category button

under the setpoint temperature display. Once selected, the number will
flash.

3 Set the drying temperature. Press Setpoint Adjust (+) or (-) buttons or enter a

low temperature (150ºF {66ºC}) on the numeric keypad and press enter.

3-8 l Installation

When configured as a central dryer, the drying temperature can
not be set since there is no process heater in the system.

Checking for Proper Air Flow (continued)

INSTALLATION NOTE: Models 150, 200, 300, and 400

These models use a three-phase process blower. If the dryer shuts down and a Process

Loop Break shutdown alarm is indicated within the first few minutes of operation, check

for proper air flow or check the Process RTD for proper installation.

If the air flow is reversed, the process blower is turning in the wrong direc-

tion. Turn off and lock out the main power source. Open the electrical

enclosure and reverse any two leads connecting the main power supply to

the dryer.

WARNING: All wiring, disconnects, and fuses should be installed by
qualified electrical technicians in accordance with electrical codes in
your region. Always maintain a safe ground. Do not operate the equip­ment at power levels other than what is specified on the machine serial
