WHAT IS THE SC CAROUSEL DRYER? The SC 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 SC Carousel Dryer achieves continuous, closed loop drying by passing air simultaneously through two heaters and three tanks of molecular sieve desiccant. HOW IT WORKS 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 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.

UNPACKING THE BOXES The SC carousel dryer comes in one to four boxes, depending on the models and options ordered.
PREPARING FOR INSTALLATION The SC 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, three-phase power source supplying the correct current for your dryer model. Check the dryer’s serial tag for the correct amps, voltage 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.
MOUNTING DRYER 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, or mount the dryer on a floor stand.
MOUNTING DRYER AND HOPPER ON A PROCESSING MACHINE Remove the hopper base plate and bolts from the bag attached to the mounting bracket/ discharge assembly. 1 Place the aluminum ring on the mounting bracket / discharge assembly. 2 Bolt the base plate to the hopper bottom. Use the four 3/8-16 countersunk bolts provided. 3 Place the slide gate on the processing machine throat. Position the slide gate so that its bolt holes line up with the holes that were drilled in the throat.
MOUNTING THE DRYER ON A FLOOR STAND; HOPPER ON THE THROAT 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) to mount the hopper on the throat of a processing machine.
MOUNTING THE HOPPER You need to assemble the hopper and discharge before mounting the hopper on the throat of the processing machine. 1 Bolt the discharge to the hopper bottom. 2 Place the slide gate on the throat of the processing machine. Use the four 3/8-16 bolts with lock washers provided. Position the slide gate so that its bolt holes line up with the holes that were drilled in the throat. If hole patterns do not match, bolt a mounting adapter between the throat and slide gate.
CONNECTING AIR HOSES Using the two flexible hoses provided, connect the inlets and outlets of the drying hopper to the dryer. If you have mounted the dryer on a floor stand, make sure the dryer is located no more than 5 feet (1.5 m) from the hopper to reduce heat loss. 1 Attach the 2 1/2-inch (6.4 cm) hose to the return air inlet in the base of the aftercooler housing and to the return air outlet at the top of the hopper. 2 Attach the 2-inch (5.
The 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 in the delivery air inlet at CONNECTING THE RTD PROBE the top of the hopper. The end of the probe must not touch the walls of the inlet. Tighten the nuts to lock the probe in place. 2 Plug the probe’s cable into the dryer control box. Coil any excess cable and secure with a wire tie.
MOUNTING A LOADER ON THE HOPPER If you have a Conair loader or vacuum receiver, you can use the flange and mounting clips provided on the top of the hopper. Refer to the manuals that came with your receiver or loader for detailed installation instructions. TESTING THE INSTALLATION You have completed the installation. Now it’s time to make sure everything works. You should perform this test with no material in the hopper. 1 2 Make sure there is no material in the hopper.
5 6 Check for proper air flow. Remove the delivery air hose on the dryer. Hold your hand near the outlet with the dryer on. You should feel air blowing out of the dryer. Moisture exhaust Delivery air outlet Flip the toggle switch to STOP to turn off the dryer. If everything is installed correctly: ◆ The green drying light stays on for two minutes. ◆ The blowers continue running for two minutes to cool the heaters. 7 START STOP The test is over.

PREVENTATIVE MAINTENANCE CHECKLIST Routine maintenance will ensure optimum operation and performance of the SC Carousel Dryer. We recommend the following maintenance schedule and tasks. ● Whenever you change materials ❒ Drain and clean the hopper. ● Weekly, or as often as needed ❒ Clean the process and regeneration filters. You may need to clean filters more often than weekly. Frequency depends on how much material you process and how dusty or full of fines it is.
CLEANING THE HOPPER CAUTION: Hot surfaces. Always protect yourself from hot surfaces inside and outside the dryer and drying hopper. The hopper, spreader cone and discharge assembly should be cleaned thoroughly between material changes to prevent resin contamination. Place a container beneath the hopper’s drain port to catch the material. . 1 2 Close the hopper slide gate. Remove the drain-port plug. Pull the pin and allow the plug to drop. 2 1 3 After draining material, open the hopper door.
CLEANING THE PROCESS FILTER CLEANING THE REGENERATION FILTER Clogged filters reduce air flow and dryer efficiency. Cleaning frequency depends on how much material you process and how dusty it is. 1 2 MAINTENANCE 2 3 Clean the filter box. Remove the filter 4 Reassemble by repeating the steps in reverse order. below the process filter box and remove the box. by turning the metal end cap. Clean the filter. If the filter is worn, damaged or clogged, replace it. Remove the regeneration filter.
If you have the optional aftercooler, you need to clean the cooling coils to keep them working efficiently. Cleaning frequency depends on the type and amount of material you process. Release the latches at 1 the top of the aftercooler. 2 Pull the coils out of CLEANING THE AFTERCOOLER COILS the aftercooler housing. 3 Clean the coils with high-pressure steam, then reassemble. Loose or damaged hoses and gaskets can allow moisture to seep into the closed-loop drying system.

When a malfunction triggers a passive alarm: ◆ The alarm light (or lights) turns on. ◆ The dryer continues to operate. Alarm Possible cause Solution Does the drying hopper contain enough material? Verify that your material supply system is working. Refer to the manuals for your conveying system, if necessary.
You can add an aftercooler to the SC Carousel Dryer by ordering the optional aftercooler coils. Installation is easy. The optional aftercooler requires a source of city, tower or chiller water and a discharge or return line. You can use water at temperatures up to 90˚ F (32˚ C). But the water flow should be at least 3 gallons (11.36 liters) per minute. 2 1 Stop the dryer and disconnect power. 2 Remove the aftercooler housing cover. 3 Insert the aftercooler coils into the housing.
