dX series This new series of mobile resin drying/conveying systems is part of the latest generation of Carousel Plus desiccant dryers from Conair. The systems use dry air to convey resin to the throat of the processing machine. Each system includes a stainless-steel hopper, conveying blower, dust collector and direct-feed vacuum receiver. An optional integral hopper loader allows the dX to load itself. The loaders can be supplied with a sensor to confirm resin fill levels and a ratio valve for loading two materials into the dryer. Units in the dX series come in several sizes, with throughputs ranging from 15 pounds per hour to 200 pounds per hour.
What's new? Numerous features, including an air-to-air after-cooling option and a new controller. Aftercooling reduces the temperature of the air returning from the drying hopper, which improves the moisture-absorption efficiency of the desiccant. With air-to-air aftercooling, the unit can efficiently dry resin while handling return-air temperatures of up to 375 degrees Fahrenheit and dew points of minus 40 degrees Fahrenheit. The new, programmable electronic controller comes in two versions: the DC-C Plus package with a 4-inch touch-screen interface; and the DC-C Premium, which has a 7-inch screen. Both offer dew-point monitoring and control, energy-use reporting, heater on-time trending and predictive maintenance features. The Plus configuration is designed for use with one loader, while the Premium can handle two, typically with one loader serving the primary processing machine and another serving the dryer hopper. Premium models have additional energy-saving features, including temperature setback, which automatically adjusts drying air input temperatures to avoid overheating, and an optional drying monitor, which uses sensors in the hopper to confirm that proper drying conditions are maintained. Premium units also offer remote access and control capabilities and enhanced monitoring and alarm functions.
Benefits Efficiency and convenience. The systems eliminate the need for machine-mounted hoppers and are contained on a convenient cart. Setup, pre-drying, cleaning and maintenance don't tie up valuable time on the processing machine. Worker safety also is enhanced because climbing on the primary machine is not necessary.
