What is the D Carousel Dr yer?
The D carousel dehumidifying dryer produces hot, low-dew point air that removes moisture from hygroscopic plastics. The dryer pulls warm, moist air from a drying hopper and pumps it through dehumidifying desiccant. The dryer then heats the air to the drying temperature you selected and circulates it through the material in the hopper.
The dryer’s three-tank, closed-loop design ensures a continuous supply of hot, dehumidified air while preventing contamination from moisture in the plant.
The D dryer can be mounted beside the hopper on the throat of a processing machine using the optional diving board support frame, or positioned on the floor near the machine using the standard casters. Two mobile floor stand designs are also available.

2 n o i t p i r c s e D
The D carousel dryer can be used successfully in applications that require:
•A contamination-free drying environment.
•Drying temperatures within the ranges shown in the following table:
Model |

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

|
|
|
|
Low-high (with aftercooler & precooler)* |
100° - 375°F (38° - 191°C) |
|
|
|
|
*Note: See instruction on page 4-12 for setpoints over 150°F (66°C).
•Throughput rates of 15 to 100 lbs (6.8 to 37.3 kg) per hour (some materials can be run at a higher rate).
•Dew points of -40°F (-40°C).
If you are drying material at temperatures over 250°F (121°C), you will need the high-temperature package that includes an aftercooler. An aftercooler is standard equipment on the High heat and Low-high models.
Central
When supplied for central drying applications, the D series dryer is not equipped with a process heater. Therefore, as a central dryer, the D dryer will only supply dry air to the hoppers.

How It Works
The D carousel dryer achieves continuous, closed loop drying by passing air simultaneously through two heaters and three tanks of molecular sieve desiccant.
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 optional aftercooler, if installed) into the dryer’s desiccant tank, where moisture is removed. The now dry air moves through the process heater, where it is heated to the drying temperature selected by the operator. The hot, 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.

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.
The Regeneration Cycle
The regeneration blower pulls air through the regeneration filter into the dryer’s regeneration heater. The air is heated to 425°F (218°C) before it is pushed into the “wet” desiccant tank. The hot air purges moisture from the desiccant. The moist air is blown out the exhaust at the back of the dryer.
The Cooling Cycle
A regenerated desiccant tank must be cooled before it is moved back into the process cycle. The process blower pushes a small amount of air through the regenerated desiccant tank. The cooling air then passes through the optional aftercooler, if installed, and repeats the circuit.

SPECIFICATION NOTES:
*SCFM stands for standard cubic feet per minute, referenced to a pre-specified pressure, temperature and relative humidity. In most cases, SCFM is referenced to 14.7 PSIA 68° F and 0% 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.

Preparing for Installation
The D carousel dryer is easy to install if you plan the location and prepare the mounting area properly.
1Make sure the mounting area provides:
A grounded power source supplying the 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 precooler.
The D dryer’s optional aftercooler and precooler can use 1-2 gals./min. (3.8- 7.6 liters/min.) tower, city, or chiller water at temperatures of 40° to 85°F (4° to 29°C). Pipe should be run to the planned dryer location. Use flexible hose to connect the water pipes to the aftercooler and precooler. If the dryer has an optional flow control, see Appendix D for connection information.
Minimum clearance for safe operation and maintenance.
You should maintain 24 in. (61 cm) clearance on at least three sides of the dryer. If the dryer is mounted with a hopper on a processing machine throat, clearance between the dryer and hopper can be 4 in. (10.2 cm).

Mounting the Dr yer and Hopper on a Processing Machine
WARNING: You are responsible for the structural integrity of this installation.
We recommend that you:
Use bolts no smaller than 3/8 inch (M 10) when mounting the hopper/dryer combination to the throat of a processing machine.
Do not mount the hopper/dryer combination on a plate that swings away or slides away from the processing machine throat. Either remove the swing or slide plate, position the dryer on the floor, or mount the dryer to an optional floor stand.
Tools for installation:
Flathead screwdriver
9/16” and 1/2” wrench
Hoist
NOTE: You must position the dryer on the floor or mount it to
an optional floor stand if your processing machine throat requires the small discharge assembly or a mounting plate with less than a 3 x 3 in.
(7.6 x 7.6 cm) bolt pattern and
1 in. (2.54 cm) diameter opening.

The dryer and hopper mount on a support frame / discharge assembly that bolts to the throat of the processing machine, as pictured above.
CAUTION: To prevent accident and injury, lift the empty hopper and support frame onto the throat of the processing machine using a hoist and the lifting lugs provided. After the hopper is mounted, then lift the dryer onto the support frame using a hoist and the lifting lugs provided.
Mounting the Dr yer and Hopper on a Processing Machine
The drying hopper, slide gate, support frame, and discharge assembly may have been shipped fully assembled. You can remove the hopper from the support frame, if you find it easier to lift and bolt the frame and then the hopper to the throat of the processing machine.
1Lift the hopper, support frame, and discharge assembly onto the processing machine throat. Use a hoist to lift the support frame and hopper. Position the frame and discharge assembly so that its bolt holes line up with the holes drilled in the throat. If hole patterns do not match, you can place a mounting adapter between the throat and the support frame.
2Bolt the frame and discharge assembly to the throat. Using four 3/8 in. -16 (M 10) self-locking bolts, fasten the support frame and discharge assembly to the throat. The bolts must be long enough to reach at least 1/2 in. (1.25 cm) into the processing machine throat or mounting adapter after passing through the discharge assembly and support frame.
NOTE: If you removed the hopper from the support frame, lift the hopper onto the frame using
a hoist. Make sure the slide gate is positioned in the recess on the bottom of the hopper base plate. Align the bolt holes and fasten the base plate to the discharge assembly using the four 3/8 in. -16 (M 10) self-locking bolts
provided.
3Lift the dryer onto the support frame using a hoist and the lifting lugs provided. Align the four bolt holes on the bottom of the dryer with the four bolt holes on the top of the support frame. Fasten the dryer to the frame with 5/16 in. -18 bolts.
