Technology news
Parker and Madison scoop awards Parker Hannifin has earned recognition as one of the United States’ top technology innovators by two influential business publications.
Parker has been named one of the nation’s “largest and most innovative users of information technology” for the tenth year in a row in a recent ranking of 500 IT leaders by Information Week (IW). And Parker was also one of only 16 winners of Start Magazine’s eighth annual Technology & Business Awards, receiving recognition in the “Industrial Equipment” category. The annual Information Week 500 survey, a listing of the most innovative IT users across the country, identifies the best technology and business practices of companies that demonstrate patterns of technological, procedural and organisational innovation. www.parker.com Madison Filters’ Cerafil division has been awarded an IChemE Environmental Award – “impact of innovation” – for its Cerafil TopKat technology, which combines exceptionally high filtration efficiency (<2mg/Nm3) at high temperature (up to 900oC) with the ability to destroy NOx, VOC’s and dioxins in a single filtration step. Cerafil won the ABB sponsored award against stiff competition from, amongst others, AstraZeneca, Merck & Co and Cleanaway.

Mann+Hummel technology targets Euro 4 emissions standard Many commercial vehicles in the world run on diesel, and many – including Germany-based automotive engineering company Mann+Hummel – believe that diesel engines are “unbeatable” when it comes to economic efficiency, service life and reliability. In addition, the tightening of NOx limits in exhaust gases has meant that new inventions are needed. Mann+Hummel reports that according to the EURO 4 standard, the limit for nitrogen oxide emissions (NOx) will be cut by 30 percent in 2005. The standard applies to vehicles with a licensed weight of over 3.5 tons. And the EURO 5 standard has again set its sights on nitrogen oxide emissions for 2008 – the limit will be cut by a further 40 percent. This necessitates companies such as Mann+Hummel working with car manufacturers on solutions to cut emissions, and this happened in the case of BlueTec from DaimlerChrysler, which significantly reduces the pollutants in exhaust flows. Mann+Hummel developed and produced important filter elements for this system. According to Mann+Hummel, two systems can essentially bring about the required reduction in emissions: particle filters, and catalytic converters that work on the selective catalytic reduction principle – SCR for short. DaimlerChrysler decided on the SCR technology at an early stage. One precondition for a functioning SCR system is the injection of a urea additive into the exhaust flow that releases
ammonia due to the heat of the exhaust gases. Ammonia allows the nitrogen oxides to convert into the harmless substances water and nitrogen.
Filters “prolong” service life Mann+Hummel’s new technology allows filtration of the urea/water solution, a source at Mann+Hummel explained in the company’s employee magazine:
Technology of the future, Mann+Hummel’s patent pending urea filter element U58 for commercial vehicles
“This [filtration] prolongs the service life of the urea/water solution metering unit and corresponding urea/water solution injection components. The urea/water solution itself is pumped from a reservoir. The filter element can be optionally mounted on the outlet or inlet side of the pump. The service life of the filter element is equivalent to the service interval for the diesel fuel filter, thus ensuring that the truck spends as little time as possible in the workshop.”
The technical specifications for the filter were drawn up by Mann+Hummel, and are now an “accepted standard in the industry for this new type of filter.” Special solutions are also needed for the choice of materials on account of their material resistance, particularly against ammonia. The effects of temperature must also be taken into account, since liquids expand when frozen, and lines can burst. This is why the
tank, filter, pump and lines, amongst others, have to be heated in winter and at low temperatures. The freezing point of the the 32.5% urea/water solution – with no further additive – is around -11°C. So the urea filter elements, the housing and other system components are designed to be freeze-proof. In addition, the volume of liquid in the housing and filter element is greatly reduced and elements are integrated that compensate the pressure of ice, the company explains. Mann+Hummel has developed the urea filter element U58 through to the start of production for DaimlerChrysler’s BlueTec system. www.mann-hummel.com (See interview with Mann+Hummel’s Dr. Michael Durst, head of filter element developments, on page 16 and 17.)
