THE NEXT
GENERATION
IN POLYMER
DRYERS
Conair’s Carousel Dryers just got better. Dubbed the Carousel
Plus -- everything about this dryer is improved to help you stay
profitable in a dramatically more competitive world market. The
product improvements are an extension of the legacy of the
original, workhorse Carousel desiccant dryers.
Model W25
Purchase this dryer and you will find that you have more control
over drying dewpoint and temperature than ever before, in a
package that is simpler, smaller, lighter, more energy efficient,
easier to use and maintain than any other dryer on the market
today.
FLOOR UNIT ON STURDY STEEL CASTERS
These small-sized dryers are small
enough to be used beside the machine, yet powerful enough for central
drying (models 50-100).
■
The Carousel Plus Dryers use molecular sieve desiccant that is bonded into
a fiberglass substrate and formed into
a continuously rotating wheel. The
result is rock steady drying temperatures and dewpoint levels, critical for
processing moisture and temperature
sensitive material.
■
These units are capable of delivering
nominal throughput rates ranging from
10 to more than 100 lb/hour.
The thermo-formed, impact resistant
ABS cover adds to the good looks and
space-saving design of the Carousel
Plus Dryers. Models 15-200 are also
available in Mobile Drying and
Conveying (MDCW) configurations.
Reduced energy costs
The desiccant wheel assembly heats and cools more easily than previous drying
technology saving you up to 35% on your energy bill. Fewer parts, lighter structural mass, less to heat, therefore less wasted energy.
Maximum uptime, maximum reliability
With significantly reduced part count, easy access and less wear you can expect
many years of trouble-free operation. The weight of the desiccant assembly
has been reduced by 70%, the part count reduced by 90%, there are no more
indexing bed plates, no more cumbersome 4-way valves and no more messy
desiccant beads. Shift-after-shift this dryer will deliver the performance you
need to stay up and running.
■
Precise, adjustable dewpoint control
An industry first! The new dewpoint control option built into the microprocessor
control system allows you to select a particular dewpoint value, which the control locks onto. The control then adjusts various dryer functions to precisely
hold the dewpoint selected, virtually eliminating any chance of overdrying
expensive material.

How it works
Regeneration
Blower
Regeneration
Air Filter
The core of the Carousel Plus Dryer is the
Munters® unique fluted desiccant rotor,
which contains molecular sieve desiccant.
The molecular sieve has been grown into
the rotor's porous fiberglass substrate,
preventing the possibility of desiccant break
down and dusting over time.
The desiccant rotor revolves slowly at the
rate of 12 revolutions per hour passing
through three cycles with each revolution.

First, the dry air is dehumidified in
the adsorption cycle, capturing and
removing moisture from the drying
air stream.
2 Next, the desiccant passes into the
high temperature regeneration cycle
where the adsorbed moisture is
heated and purged out of the desiccant to the atmosphere.

Aftercooler/Intercooler
of the rotor produces a resin-drying low

and offers multi-year media life with
virtually no maintenance.
The continuously revolving rotor provides
rock steady temperature and dewpoint
control.
The rotor technology minimizes energy
consumption by reducing the structural
mass, less structural mass to heat means
less energy wasted.

The desiccant is then
advanced to the postregeneration cooling cycle
and cooled with closed
loop dry air. All Carousel
Plus Dryers feature this
unique closed loop cooling
technology to eliminate
moisture that can cause
defects in parts.
Drying Monitor, DM-II option to HY Packages -
Saves you time and money, and from the aggravation of dealing with improperly
dried material.
The DM-II automatically monitors the temperature profile inside your drying
hopper within a pre-set temperature band to protect you from overdrying or
under drying your material. A warning alarm shown on the control display and
light tower alerts you to improper drying conditions. This advanced notice
provides time to diagnose and correct otherwise undetected problems that can
lead to defects in products manufactured from hygroscopic material.
This valuable option can help you uncover common drying problems that may
exist, including: a failed or out-of-place process RTD; improperly sized hoppers
or dryers; drying or loading equipment failures; reduced airflow caused by dirty
filters; kinked hoses and other obstructions, throughput change, loss of power or
overheated material.
The DM-II does not alert you to the specific drying problem, however, the DC-2
control will identify most dryer related faults. Available on models W50 and
above.
FEATURE DESCRIPTIONS
● Audible and visual alarm - A combination of a blinking red alarm light
and a horn alert the operator to any shut down alarm.
● Temperature setback - Automatically reduces the drying temperature to
a lower standby mode when the machine throughput is reduced or stopped.
● Dewpoint monitor - Allows the operator to monitor the performance of
the dryer by providing a digital dewpoint readout of the drying air.
● Dewpoint control - Allows the dryer to lock onto and track an operatorselected dewpoint level. This feature helps prevent overdrying of moisture
sensitive materials such as Nylon. The Carousel Plus is the first dryer in the
plastics industry to provide precise dewpoint control.
● Communications - Allows the dryer to be networked to industrial control
systems. When a dryer is connected to a network the controller on the network
may read actual temperatures, change setpoints, read dryer status, and process
and display this information at a central location. DeviceNet, SPI, Modbus and
Ethernet communications are available.

APPLICATION NOTES:
* Material throughputs are based on typical virgin material with initial moisture content as supplied by the material
suppliers. Consult Conair if specific initial and final moisture content of your material are known for your application.
† The parameters of drying temperature and time may vary depending upon the type, grade and manufacturer of the
material being processed. Consult your material supplier for their precise recommendations.
‡ Unit of measurement for bulk density is lb/ft3. Bulk density listed is the nominal weight for typical pellets. The bulk
density may vary somewhat depending upon the size and shape of the pellets. The bulk density of regrind may vary
widely depending upon the size and the shape of the flake. Be sure to consider the bulk density of the material when
selecting the capacity of the drying hopper and the drying time desired.
§ Throughputs will vary by type of material. Consult Conair concerning throughputs for materials that are not listed here.
**All Conair Dryers are equipped with an aftercooler as standard. The aftercooler reduces the temperature of the return
air from the drying hopper, improving the efficiency of the desiccant. The aftercooler must be connected with the proper
water flow rating and temperature to attain the listed throughput.

When to use central models
Central dryers do not have process
heaters. These models should be used
when drying multiple materials that
require different drying temperatures.
Central models dehumidify the process
air, which is then heated to the correct
setpoint by a Hopper Temperature
Controller (HTC) or a “pre-heater”
mounted on the hopper.
When to use additional filtration
The standard return air cartridge filter is
sized for the airflow of each dryer model
and is suited for most applications. You
should consider adding an optional dust
collector and/or volatile trap if:
●
The material contains excessive fines. An
additional dust collector or cyclone will
extend time between filter cleaning.
●
The material produces volatiles during
drying which condense into a waxy or
oily residue. A volatile trap will help to
protect the desiccant.
SPECIFICATION NOTES:
* Dryers running at 50 Hz will have 17% less airflow, and a 17% reduction in material throughput.
† Total kW listed at a process setpoint of 250°F {121°C} and a regeneration temperature of 350°F {177°C}.
‡ When drying below 150°F {66°C} a precooler is required.
§ Temperatures above or below the recommended levels may affect dryer performance. Tower, chiller or
municipal water sources can be used.
Specifications may change without notice. Consult a Conair representative for the most current information.
