In June, the newly developed, dust-tight OEB version of the DDSR20 2.0 twin-screw feeder (photo) passed the highest occupational exposure bands (OEB) classification certification, OEB5. OEB classifications are used to grade substances accurately into “classes” or “ranges” based on the health effects and efficacy aspects of the chemicals involved. The DDSR20 2.0 OEB is suited for feeding requirements in pharmaceutical applications or handling of hazardous materials, for example in battery manufacturing. To provide dust-tight, reliable seals, all feeder seals feature specially designed sealing systems. The leak check opening in the twin gearbox is sealed with a sight glass to maintain functionality and to prevent ingredient leakage in the event of shaft-seal failure. — Kubota Brabender Technologie GmbH, Duisburg, Germany
With a minimal footprint of approximately 1 m², the compact Aircenter systems (photo) are available for flowrates from 0.34 to 2.7 m³/min and also provide application-specific compressed-air treatment and storage. All Aircenter models are characterized by their exceptional efficiency. At the heart of the two largest models, the Aircenter 22 (11 kW) and the Aircenter 25 (15 kW), is an optimized SK series rotary screw compressor. With a maximum flowrate of 2.7 m³/min, SK models deliver between 11 and 14% more compressed air, respectively, than their predecessors, the company says. This performance boost has been achieved both through airend optimization and the minimization of internal pressure losses. In turn, these improvements have led to a reduction in specific power of up to 5%. — Kaeser Kompressoren SE, Coburg, Germany
The technically advanced LoKr reverse rupture disk (photo) delivers a best-in-class flow-resistance factor, KR, to maximize pressure-relieving performance while delivering superior reliability and service life. The disk’s architecture has been refined and optimized to improve performance in three key areas: keeping pressure drops in relief lines to an absolute minimum, providing maximum reliability and accuracy and being suitable for the widest range of pressures, temperatures and line sizes possible. The reverse-buckling disk combines a dimple on the disk with an innovative knuckle on the holder to offer full-bore opening with exceptionally accurate burst ratings. This enables a higher flowrate on burst than previously possible, demonstrated by the disk’s low KR value of 0.22. This makes it easier to keep pressure drops across the relief line below 3%, when the LoKr is used in relief valve isolation. Process plants can continue to use smaller piping diameters with no loss of performance or efficiency, even at low flowrates. — OsecoElfab, Broken Arrow, Okla.
