The goal of model predictive controller (MPC) supervision is to ensure that the MPCs continue to run optimally. Without performance supervision in place, MPC performance often degrades over time, even to the point of being disabled by operations, says the firm. PlantTriage Performance Supervision software now supervises MPCs, using economic information and controller data to calculate assessments that quickly indicate if the MPC is continuing to provide a high return on investment. Within PlantTriage, MPC performance is tracked, trended (photo, upper left), and historized at the controller, unit, plant and site levels. Web-based visualization tools display the information in an intuitive manner. “Drill-down” capabilities are used to drive analysis to root cause. One of the unique MPC assessment features included with PlantTriage is Controller Entropy, which detects and tracks when a controller is making moves, which results in cycling between constrains. — ExperTune Inc., Hartland, Wisc.
Based on the same hydraulically balanced diaphragm principles as traditional diaphragm metering pumps, the Hydra-Cell Metering Solution (photo, lower) can save as much as 20–30% on initial purchase, says the manufacturer. Evaluation of lifetime costs has shown that significant savings can also be made in terms of maintenance, repair and energy costs. The multidiaphragm pump head produces very low pulsation, removing the need for pulsation dampers in many systems, and eliminating expensive multiplexing pump arrangements. Having no dynamic seals, the pump can handle abrasive, corrosive, viscous and non-lubricating fluids. — Wanner International Ltd., Church Crookham,

A new generation of vacuum conveyors and Multijector Vacuum Pumps (photo) were unveiled at Achema by this manufacturer. A new nozzle system, designed using flow simulations and empirical data, is said to decrease compressed-air consumption while increasing the suction capacity. With the vacuum conveying system, cross contamination is avoided because all parts that come into contact with the material to be conveyed can easily be disassembled and cleaned without tools. Washing and CIP functions are also available as a modular upgrade for the conveyors. Unlike pneumatic conveying, which uses a positive pressure, vacuum conveying is inherently dust-free because dust clouds are sucked in and the powder transfer takes place in a closed loop; material flow cannot leave the transport hose or pipe. As a result, the system is especially suitable for conveying very fine powders, such as toner. — Volkmann GmbH, Soest, Germany
At Achema, this company introduced the “premium line”, a new generation of planetary mill, which offers improved handling, power and safety.
