point setting, target moisture level, for example. The Alarms display offers real-time alarm status and a complete alarm history, together with a special panel that allows managers to create a hierarchy of alarm types, generate messages (texts or e-mails) specific to each, and direct/delegate alarm responses to selected individuals or groups of plant personnel. Even as individual users interact with data from their equipment, the Conair SmartServices platform collects, analyses, and stores performance data from their auxiliaries and thousands of others connected worldwide. The result is an ever-grow- ing auxiliary-equipment database that can be leveraged by both processor and Conair personnel to improve efficiency, performance and uptime. Already, that information is beginning to be mined and used to develop algorithms for a range of predictive, diagnostic and comparative purposes. New developments in the operation and
application of Conair’s Wave Conveying material handling system now give processors a wide range of options to achieve control over the vacuum conveying process. One of the newest enhance- ments is an ‘automatic flush’ valve that eliminates valve-sealing problems, reducing receiver fill times and effectively increasing system capacity. The system now makes it possible to move any resin, at
virtually any speed, with higher throughputs over longer distances – without the material and equipment damage normally associated with conventional, dilute-phase vacuum conveying. Conair has also added an advanced auto-flush- ing common line valve to its Wave Conveying system, which is claimed to maximise throughput by eliminating even the briefest valve-sealing problems that can occur with some material types. By ensuring the most rapid and positive valve seal on every fill cycle, the action of this valve signifi- cantly reduces receiver fill times and effectively increases Wave Conveying system capacity. The Wave Conveying system uses Conair LDP Series vacuum pumps equipped with variable frequency drives, which can operate at the precise level of capacity and power consumption needed to maintain a specific material velocity in the system. The hardware, together with the FLX-128 Plus control, regulates material flow, fine tuning both the vacuum level and the influx of material from the material supply point to the conveying system. In addition, there is a conveying speed sensor, which measures the speed of material (not the speed of the air) as it moves. It provides feedback to the FLX control and Wave Conveying system, helping the system maintain even and correct material flows throughout. Material-specific recipes are pro- grammed into the FLX control, which enables the system to automatically change conveying speeds and characteristics to suit the requirements of any material.
Now available as an option for the FLX-128 Plus
Unlike conventional dilute-phase conveying (top), Conair Wave Conveying technology moves resin in compact slugs of material that travel at much slower speeds

material-handling control system or as a stand- alone control package, Conair’s Railcar Unloading (RCU) controller offers processors a time-saving, secure and expandable way to monitor and manage the unloading and storage of railcar-quan- tity resins from any convenient indoor location. The RCU controller enables any authorised user to view and manage the entire process on one touchscreen – railcar unloading, silo selection, material routing, and silo filling – without the need to go outside. The RCU package integrates control
