New Products be installed in Zone 1. Both employ the same electronic boards in their plug-in modules. These have now been modernized to comply with the latest ATEX guidelines and standards, while remaining compatible with exexisting devices. Standard buses, such as Profibus, Modbus or industrial Ethernet are available for connecting to master systems. The devices feature new, compact redundant backplanes to save space and reduce costs. Extended intrinsic safety parameters facilitate new interconnections with even more field devices. — Pepperl+Fuchs GmbH, Mannheim, Germany www.pepperl-fuchs.com A laboratory capsule-filling machine gets an upgrade Replacing its predecessor, the new GKF 702 capsule-filling machine (photo, p. 20I-7) has been designed to produce small batches directly in the laboratory. The parameters required later for production, such as machine speed, can be fully simulated. Therefore, the machine can produce small batches for R&D or clinical purposes under realistic production conditions. A special filling station, called the Mini-Bowl, was developed for small product batches (100–300 mL) and delivers high yields, which is important for expensive and limited powder volumes. A slide-gate system is also available for higher batch yields and for filling free-flowing granulates or pellets. — Bosch Packaging Technology, Waiblingen, Germany www.boschpackaging.com An O 2 -sensor for welding The PurgEye 500 Weld Purge Monitor uses a nonchemical sensor that measures oxygen levels down to 10 ppm, but yet is only a fraction of the cost of alternative instruments designed to do the same work. A special pump inside the PurgEye housing extracts samples of exhaust gas for checking the quality of the Weld Purge Gas around the weld root. The instrument has an alarm that activates when the Emerson Process Management 20I-6 CHEMICAL ENGINEERING WWW.CHE.COM AUGUST 2011 O 2 levels around the weld exceed the desired value, and an associated alarm shuts the welding machine off or on again as the O 2 levels fluctuate, to ensure a perfect purge all the time. — Huntingdon Fusion Techniques Ltd., Carms, U.K. www.huntingdonfusion.com This filter tackles difficult liquid filtration challenges The new ZCore depth cartridge filter (photo) is said to offer improved performance, less downtime and reduced operating costs. The ZCore is especially suited for extreme applications where traditional cartridge filters are not effective, such as hot-water sanitizing, high-temperature chemical processing, and very dirty streams where significant pressure drop can develop. The ZCore is available in a variety of micron ratings and lengths, and offers a 90% efficiency for particles as small as 0.5 µm. The filters meet the criteria for use in USP Class VI environments and functions at maximum pressure differentials ranging from 15 psid (1.03 bars) at 180°F to 60 psid (4.14 bars) at 86°C. — GE, Trevose, Pa. www.ge.com GE SensoTech A catalyst extends the shelf life of polymer mixes This company has developed its CSR family of latent acid catalysts to create formulations suitable for production of stable phenolic and furanbased polymeric mixes with more than three months shelf-life at room temperature. These inherently flameretardant bulk and sheet-molding compounds maintain good mold-flow characteristics and can be cured rapidly at 120°C or more slowly at 50°C. Applications requiring flame-retardant moldings include interior fittings for all forms of transportation, electrical insulation products and electronic and electrical systems packaging. — Bac2, Southampton, U.K. www.bac2.co.uk This multimotion dryer is kind to sensitive products The Planex System (photo, p. 20I-7) is a patented, horizontal paddle vacuum dryer developed for vacuum drying of wet powders obtained from a centri-
Bosch Packaging Technology Italvacuum fuge or filter press. The system consists of a fixed cylindrical chamber with an eccentric agitator inside with two independent movements: it can rotate on its own axis and tangentially to the cylindrical chamber as well. This combined double rotation allows optimal product mixing, continuously renewing the surface exposed to evapora- Get Chemical Engineering’s plant cost index to improve plant cost estimates…and delivered in advance of the print edition! For more than 37 years, chemical process industries professionals- engineers, manager and technicians, have used Chemical Engineering’s Plant Cost Index to adjust process plant construction costs from one period to another. This database includes all annual archives (1947 to present) and monthly data archives (1970 to present). Instead of waiting more than two weeks for the print or online version of Chemical Engineering to arrive, subscribers can access new data as soon as it’s calculated. Resources included with Chemical Engineering’s Plant Cost Index: • Electronic notification of monthly updates as soon as they are available • All annual data archives (1947 to present) • Monthly data archives (1970 to present) • Option to download in Excel format Subscribe today at www.che.com/pci tion. As a result, the release of solvent vapor is facilitated and drying times are significantly reduced compared to conventional systems, says the manufacturer. The unique configuration of the agitator and the double rotation provides continuous revolution of the product while limiting the mechanical and thermal stress, preventing 17817 local overheating due to friction. The mechanical stress on the product is said to be three times less than that produced in traditional paddle dryers equipped with concentric agitators. This property makes the system ideal for drying heat-sensitive products, and also leads to a reduction in power consumption by about one third.
