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.

This C Series heat exchanger (photo) replaced an older shell-and-tube design that had high operating costs, due to a 2.4 psi pressure drop. While both old and new units have the same capabilities, the new C Series pressure drop is only 0.1 psi. The lower pressure drop will save 50 hp in power, which translates into energy savings of about $50,000/yr. The housing is constructed from stainless steel. The unit will cool at a rate of 5,000 ft3/min at 12 psi from 250°F to 65°F using 55°F cooling water. Features include a washable metal filter ahead of the cooling core, and an aluminum mist eliminator downstream that is removable and washable. The fin-tube core can be removed from the liquid-connection side of the housing for inspection without disassembling the gas duct. A variety of gas connection sizes and types are available. — Xchanger, Hopkins, Minn.
The Delta Hybrid series (photo) offers an innovative solution for the pneumatic conveying of sensitive, powdery and granular media. The rotary lobe compressors or screw blowers can offer maximum energy efficiency, minimum lifecycle costs, 100% pure and reliable process air and high durability even under extreme conditions. Now, the company has expanded the series with a new range of four package sizes. The new additions cover volume flows from approximately 2 to 30 m³/min and drive powers from 7.5 to 55 kW and achieve enormous energy savings of up to 30% compared to a conventional positive displacement blower. Thanks to ATEX certification and hygienic design, the Delta Hybrid machines can be used without any problems in both highly critical, explosive and particularly hygiene-sensitive working environments — Aerzener Maschinenfabrik GmbH, Aerzen, Germany
At Powtech last month, this company presented completely new, more wear-resistant screen cloths that, compared to previous standard cloths, achieve an increased service life with abrasive bulk materials. Matched to the wire thickness and mesh size, the screen cloths are manufactured in a patented process, which significantly increases their wear resistance (photo). A particular advantage here is that, depending on the application, existing screening machines can also be equipped with these robust screen cloths. This innovation increases the plant availability of the users and reduces their downtime and maintenance costs. — Allgaier Process Technology, Uhingen, Germany

The Vertical Cartridge Filter (VCF; photo) is a pulse-jet filter designed to handle medium to high air volumes for industrial dust removal. It is typically used as a nuisance dust collector in applications with light dust loads and a high volume of air flow. An easy-to-use cartridge clamp system on the hinged front doors of the baghouse provides easy access to and rapid replacement of the filter media. This minimizes downtime during scheduled maintenance, decreasing overall cost of operation. The filter is equipped with a smart timer, which includes an on-board sensor that reads the pressure drop across the filtering elements for on-demand cleaning. This results in reduced compressed-air consumption and greater cartridge life, the company says. — Schenck Process LLC, Kansas City, Mo.
