SEW-EURODRIVE has been offering IE3 motors of the DRN… series since the end of 2014. This means that the company meets the efficiency requirements that are mandatory in accordance with the legal requirements that have been in force in Europe since January 1, 2015. Now the one millionth DRN.. motor has been awarded to a customer.

In 2009, the European legislator stipulated the minimum efficiency levels for the use of three-phase asynchronous motors in the European Economic Area in Regulation VO 640/2009. Initially, IE2 motors from 0.75 to 375 kW were required in a staggered timetable as of 16.06.2011. Since 01.01.2015, motors with an output of 7.5 to 375 kW for grid operation then had to be supplied in the IE3 energy-saving class. In the third stage, the EU increased the minimum efficiency to class IE3 as of 01.01.2017 already for motors in mains operation from 0.75 kW.

In February 2021, the company PRG Präzisions-Rührer GmbH from Warburg near Kassel ordered 20 identical KAF87 DRN112M4/TF bevel gear motors. With the third partial delivery, the series counter of the IE3 versions jumped over the limit of one million energy-saving motors delivered in Germany. The company’s managers would have liked to hand over the motor and an anniversary certificate to the customer in person, but this was not possible due to the pandemic situation. Instead, the handover to the managing partner of PRG Präziosions-Rührer GmbH, Frank Dierkes, took place digitally. Patrik Menges, sales management and Gregor Dietz, market manager for motors, handed over the bevel gear motor with certificate and additional identification plate on April 15, 2021 and thanked him for the order.

This quantity of motors represents a significant reduction in primary electrical energy required. Even if no reliable information is available on the time of use and the actual load and unload of the motors in the applications, a good estimate can be used to calculate a saving of more than 400 GWh. Expressed differently, this is more than 135,000 t CO2.

Cooperation for sustainable investment

KHS and Martens are continuing their joint strategy for reducing packaging material. Just last year the traditional Belgian brewery invested in an Innopack Nature MultiPack machine which uses adhesive dots to join PET bottles into stable packs. Now the group is planning to purchase a second NMP machine, which processes cans, from KHS. Thanks to the expansion the brewery will have greater flexibility to meet the market’s growing demand for environmentally friendly packaging. The NMP project is just one example of the Dortmund-based full-range supplier’s steadily growing portfolio of sustainable packaging solutions.

Since 2020 the company has been relying on the material-saving Nature MultiPack from KHS. Together the long-standing partners implemented film-free six-packs made of PET bottles for the retail trade. The response to the alternative to classic shrink film has been very positive:

 

“We were able to convince both our customers and consumers. The high demand shows that environmentally friendly packaging is in high demand.”

– Jan Martens, Brewery Manager

 

Into new markets with Nature MultiPack

Thanks to the new line, the Belgian beer producer will in future be able to process not only PET bottles but also cans into stable yet easily separable packs. This eliminates the need for shrink film or cardboard packaging and reduces material consumption by up to 90 percent. “This benefits both consumers and the environment,” says the brewery boss.

While the brewery produces at an output of up to 54,000 containers per hour, which is sufficient for them, KHS now also offers the Innopack NatureMultiPack machine for the high-performance range. This further developed variant enables up to 90,000 containers per hour – and even up to 108,000 if the capacity is exceeded.

This should make it possible to penetrate new markets. “Retailers are increasingly looking for environmentally friendly packaging options. I am very confident that our resource-saving Nature MultiPack solutions will meet with great interest,” predicts the brewery boss. Now his brewery has the necessary flexibility to meet the current needs of the trade in the best possible way.

 

Secondary packaging: KHS offers an extensive portfolio

The Nature MultiPack is just one example of the continuously increasing variety of sustainable and forward-looking secondary packaging from KHS. The Dortmund-based full-range supplier pursues a clear strategy of taking a holistic view, as Sören Storbeck, Global Product Account Manager Packaging at KHS, explains, “Our overriding aim Page 3 of 6 is to meet every need of our customers in the best possible way. We therefore rely on a comprehensive portfolio of line and packaging solutions, as well as on our global service network, which is available to our customers around the clock.”

The line manufacturer’s latest innovations include the Innopack Kisters Wraparound Shrink Paper Packer (WSPP A), which can pack cans either in paper, cardboard or film. This variety is made possible by the modular design of all Innopack Kisters machines. This allows existing models to be quickly and flexibly retrofitted with additional paper functionality. With its combination of different process modules, a WSPP A, for example, can process three different types of secondary packaging: the wraparound carton, the tray, and the pad, which can be wrapped either in paper or shrink film. As of now, it is also possible to process film made from 100 percent recyclate on Innopack Kisters machines – without any loss of quality or performance.

Another pioneering packaging alternative can be produced with the new Innopack Kisters CNP (Carton Nature Packer). This high-performance, flexible packer uses corrugated cardboard and solid board tops to join cans together to form rigid packs. KHS’ development spirit doesn’t stop there, however: “We’re striving for even more efficient and sustainable solutions – whether in the field of primary, secondary, or tertiary packaging,” says Storbeck. “Together with our customers and partners we’re constantly working on conserving even more resources and further strengthening the recycling loop.”

Innovation from proven technology

Because of the dust which arises when products are created, grinding places particularly high demands on the technology used. The design of a grinding plant with regard to safety, for both machines and their operators. The pressure shock resistant design of the complete grinding system up to an explosion overpressure of 10 bar(g) is the most frequently used version, which, however, is associated with a high level of equipment and corresponding space requirements.

Thanks to the ATEX-compliant Condux® Compact plant concept, the installation of a high performance grinding plant for numerous products is now much easier, since explosion protection valves or explosion suppression devices, explosion isolators, fans and even conventional dust filter systems are no longer required with the newly developed plant concept.

The idea of a compact grinding system is not new but existing solutions show significant disadvantages when it comes to cleaning efforts and hygienic design. NETZSCH has therefore improved the decisive points of its concept once again: The footprint or space requirement of the compact plant is 80 % less than that of comparable standard grinding plants with the same throughput capacities. This also has an effect on the investment costs, which are approximately 30 % lower. By using the newly developed CycloFil cyclone filter in the system, the integrated pre-separation of the grinding stock and the recirculation of the process gas allow a filter area that is over 90 % smaller than that of comparable mill sizes. With CycloFil, the degree of separation can be adapted to the operator’s requirements by means of exchangeable immersion tubes.

These features of the new system result in various advantages. For example, the grinding system can be easily integrated into existing production systems thanks to the minimal space requirement, and the necessary cleaning when changing products is extremely quick thanks to easy access to the parts in contact with the product.

The well-proven Impact Mill Condux® is the basis machine of this grinding system. The products are ground within this mill mainly by impact and shearing action. For use with a wide variety of products and final finenesses, this machine is available in various executions, as either a blast mill, pin-disc mill or wing-beater mill.Press release – NETZSCH Grinding & Dispersing In contrast to conventional grinding plants, the processing gas in the streams in a circular motion. The product is fed directly to the mill via a pressureshock-resistant rotary valve and discharged after the grinding process via a separator with air lock. Parallel to this, the additional rinsing air fed through the valves and mill bearing is continuously discharged through the CycloFil to prevent a build-up of pressure. A subsequent aspiration system generates the vacuum needed to stabilise the system pressure.

Thanks to the innovative CycloFil cyclone filter, the supplied energy is dissipated via the product and the system surface, so that no additional cooling is required. The warmth produced by the grinding process is mainly compensated along with the product when it leaves the machine and to a smaller extent by the system surface, and is therefore throughput dependent.

The expected temperature increase, for e.g. of ground powdered sugar (d90 = 100 μm) is normally in the range of ∆T = 10-25°C. For a large range of products the warming has no influence on the quality or the downstream process. For the grinding of particularly temperature-sensitive products, the system can be additionally cooled with liquid nitrogen. Especially the degree of innovation of the System was confirmed recently by the Fi Europe Innovation Award jury, who awarded the fine impact mill Condux® Compact as the winner of the Food Tech Innovation Award for the most innovative technical processing solution for food ingredients.
