SCHEUCH SETS SAIL: ALL AROUND THE GLOBE – STRAIGHT FROM THE INNVIERTEL The target is clear: this year the air technology market leader is once again pushing for a stronger presence in the world markets – the familyoperated company wants to operate on a global scale in the future. “We are at a stage of maturity,” say the two Managing Directors of Scheuch GmbH, Stefan Scheuch and Jörg Jeliniewski. The first steps proved to be extremely successful, and Scheuch is now ready for more.

With an export rate of around 80 per cent, Scheuch has always focused heavily on foreign markets. Out of the company headquarters in Aurolzmünster, Austria, products have been and will continue to be supplied to the whole world, Not only is the global expansion a major goal in the strategic realignment, but also it will give Scheuch two decisive advantages: in the future, simple components are to be produced and processed locally – as a result the company is 04

eliminating long delivery routes covering large distances and a lack of local processing opportunities whenever and wherever possible. Depending on the relevant markets, control of sales, project management and procurement will also be decentralised. There‘s no stopping Scheuch now... internationalisation is in full swing and will continue to be pursued resolutely in the future.

SCHEUCH GOES GLOBAL The acquisition on the US company CAMCORP is proof, how serious Scheuch takes it‘s global goal! The purchase of the firm with over 70 employees offers the ideal starting point for breaking into the North American market. The medium-sized, family-operated company from the state of Kansas is considered to be one of the market front-runners in air technology in the North American region and generated turnover of around 18 million US dollars last year.

was recently founded. Out of the office in Bangkok, Thailand, Managing Director Andreas Köck is determined to support and strengthen local environmental consciousness and can already report initial success.

A CHANCE TO INCREASE ENVIRONMENTAL AWARENESS Generally speaking, Asia is a very promising market for Scheuch‘s portfolio: concentrated economic power, increasing environmental awareness and the ever-growing need to meet new environmental standards lay the groundwork for Scheuch, the pioneer of air purification. In terms of the statutory limit values, China will draw level with Europe in the coming years.

“Transferring know-how from the USA to Austria and vice versa is especially important to us. The technologically advanced product spectrum of our new subsidiary is supported by a great deal of knowledge. In this case, we can both learn and benefit from one another – CAMCORP, for example, is making progress in industries in which we are “Basically, we are open to all regions of Our European customers sell their systems not yet active,” explains Stefan Scheuch, the world, but, of course, we make an across the globe.

THE WORLD IN OUR SIGHTS, HOME IN VIEW On the other hand, Scheuch also has a long tradition of commitment to its home region. “Expanding our international presence promises growth and also strengthens our roots here in the Austrian Innviertel region,” emphasizes Stefan Scheuch. Products with high production demands will continue to be produced in the main plant. Furthermore,basic research, one of the cornerstones of the company‘s success, also takes place exclusively at the site in Upper Austria. Scheuch employs 1000 members of staff globally, with over 600 just at the headquarters in Aurolzmünster. And the company no only focuses on global expansion – also in Austria, Scheuch is growing: last year the former wood division became a separate entity and was rebranded as Scheuch LIGNO GmbH. Together with the expertise of acquired company LBH GmbH from Wolfsegg, Austria, all customer needs, ranging from craftsmen right up to industrial enterprises, can be covered with bespoke solutions. In total, around 8 million euros were invested in the new site in Mehrnbach, Austria, to construct the new office and production buildings for Scheuch LIGNO GmbH.

Moreover, a separate position has been created in Scheuch mana gement for “Business Development”; the “Mergers and Acquisitions” department is taking on the new challenges. Stefan Scheuch: “Future international subsidiaries should be closely networked with the main site.”

A FAMILY-OPERATED COMPANY AS ALWAYS Despite all the efforts made towards internationalisation, Scheuch through and through remains a family-operated company that stands for reliability and innovative spirit. The Research and Development department is continually working on the further development of products in the on-site technical center, thus keeping Scheuch at the forefront of air purification technology.

Expanding our international presence promises growth and also secures our roots here in the Austrian Innviertel region. Stefan Scheuch, Managing Director of Scheuch GmbH

GROWTH WITH CARE Whatever objective you are pursuing, it is important to act with the necessary entrepreneurial caution. The company is currently in a development process and is exploring the opportunities of the relevant markets. Along with technical expertise, a knowledge of and regard for cultural idiosyncrasies and mentalities is indispensable when breaking into new markets. “This is why it obviously makes sense for us to also employ members of staff locally from the relevant cultural circles,” explains Jörg Jeliniewski.

Scheuch GmbH supplies a diverse range of industries worldwide with its air purification technologies: the wood, wood-based panels, energy, metals and industrial minerals sectors, as well as the devices and components business, are all part of the company‘s domain. In addition, agriculture, the food industry and pharmaceuticals are also becoming ever more important – and Scheuch‘s process engineering is acting accordingly.

INTERVIEW CORNER

INTERVIEW:

SCHEUCH ASIA LTD.: NEW HUB IN THAILAND In founding Scheuch ASIA Ltd. in Bangkok, the air purification pioneer from Aurolzmünster has taken another important step in the direction of globalisation. Starting with Thailand, the company group intends to break into the promising market in South East Asia. At the same time, Scheuch would like to be closer to its existing customers and provide them with the best possible local care.

The door is already ajar. Andreas Köck, Managing Director Scheuch Asia Ltd.

In October, members of the Scheuch management team met for the first time at the headquarters in Bangkok. At this meeting, Andreas Köck, Managing Director of Scheuch ASIA Ltd., was able to report some initial success: working together with the sales teams from Austria, a considerable number of orders for the wood-based panels, energy and industrial minerals industries have already been fixed. As a quality provider from Europe, the Scheuch Group pursues very promising projects and demonstrates a reinforced market presence by taking part in relevant trade fairs. The result of this approach is a steady expansion of the customer network.

You have been on site in Bangkok for a good ten months now. Can you describe your experiences so far? Andreas Köck: “Scheuch has already been supplying the region with air technology for many years. In this sense, the door is already ajar. Bangkok is intended to serve as a hub for South East Asia. Many countries in this part of the world are taking the leap into environmental technology and are very interested in this field. However, in some parts there is still an enormous lack of knowledge. In these cases we still need to provide a lot of information and education. In addition, clear interpretations of the law are not always available.” What is your typical daily routine? Andreas Köck: “There is no daily routine – every day is different. I travel a lot and visit customers, authorities and potential sales partners. I aim to get to know as many people as possible and to establish a network for us.”

Andreas Köck, Managing Director of Scheuch ASIA, surrounded by the skyscrapers of the vibrant metropolis of Bangkok.

What does Scheuch ASIA Ltd. focus on? Andreas Köck: “We would like to focus on the wood-based panels and cement industries – flue gas cleaning is also part of this. We haven't settled on any particular industry within the environmental technology sector; instead we concentrate on the products in our portfolio. As a technology leader in many sectors, we are in a position to share our expertise and to combine the best of both worlds with the local presence we now have.” What are your goals for the coming years? Andreas Köck: “In the last few years, we have focused on other markets. With this subsidiary, we are sending out a clear signal to our customers that we want to build a long-term base in Asia. Our office in Bangkok provides our customers and partners with a local contact with many years of expertise within the Scheuch Group.”

INDUSTRIAL MINERALS

ONE OF THE CLEANEST CEMENT PLANTS IN THE WORLD Kirchdorfer Zementwerk describes itself as one of the cleanest cement plants in the world. Proof of this claim made by the Upper Austrian industrialenterprise is found in the world's first DeCONOx system.

INDUSTRIAL MINERALS

“We have invested over 23 million euros in environmental protection in the last 15 years,” says plant manager Anton Secklehner proudly. “We feed the excess process heat into the district heating grid which is used to supply over 1000 families and businesses in Kirchdorf with environmentally friendly heat. Working together with our innovative partner Scheuch, we have now turned another milestone into reality with the world's first DeCONOx system.” Originally, the Kirchdorf plant was only planning a new flue gas catalyst. The system was even already approved. But the idea of Scheuch's technicians to use the energy contained in carbon monoxide (CO) to generate heat for denitrification was so popular that the Managing Directors stopped the existing project and decided to test the function with a pilot plant instead.

Working together with our innovative partner Scheuch, we have now turned another milestone into reality with the world's first DeCONOx system. Anton Secklehner, plant manager at Kirchdorfer Zement

THE PILOT WAS A GREAT SUCCESS Planning began in 2008, and the pilot plant was installed on the cement plant site at the end of 2010. The results impressed the managers of the Kirchdorf cement plant so much that they commissioned Scheuch in the summer of 2014 to convert the pilot into an industrial plant.

TWO SOLUTIONS IN ONE PLANT Two exhaust gas cleaning procedures are combined in the DeCONOx system. In a simultaneous process, nitrogen oxides (NOx) are reduced at the same time as carbon monoxide (CO) and organic carbon compounds (VOC). Stefan Huemer, Team Leader for Technology in the Industrial Minerals Industry division, explains how the new system works. “Crude gas flows into the system from below. It flows through the regenerator layers and is heated to 250–450°C. Denitrification then takes place in the catalyst through the addition of ammonia. The gas is heated to the firing temperature of 850°C with additional regenerator layers. This causes the organic carbon compounds to combust in the combustion chamber. The hot gas flows out of the other side of the system and transfers the heat to the regenerator layers on that side. Then the direction of flow is changed so that the energy just supplied by the gas can be reused.”

THE RESULTS SPEAK FOR THEMSELVES The results of the exhaust gas measurements send a clear signal. NOx is reduced by around 75%. CO and VOC can also be reduced by more than 99%. “Combined exhaust gas cleaning means that fuels and secondary fuels can be used in a much more flexible and efficient manner,” says Alois Hermandinger, manager of the Industrial Minerals division at Scheuch, explaining a further advantage of the new procedure.

COMPACT DESIGN The compact system design is also impressive. The technology can be integrated into existing operating plants without taking up a lot of space. Nevertheless, as assembly of the industrial plant began in Kirchdorf in February 2015, even the small dimensions still seemed 09

INDUSTRIAL MINERALS

too big. “We managed to fit the system into a trench that was scarcely nine metres wide and around 30 metres long,” explains Huemer. “The pipeline routing was a particular challenge. Poor pipe routing leads to pressure loss which is reflected in the operating costs. Maintenance access during operation also had to be borne in mind. Material stress due to the temperature differences from 150 to 850°C was another tricky problem for system engineering. But our team mastered these tasks brilliantly.” Despite the tight space, assembly was completed after just six months through the use of a revolving tower crane and many pre-assembled parts.

FLIP THE SWITCH – AND IT WORKS The new DeCONOx system was commissioned even more quickly. As the managers were still discussing the commissioning process, a plant technician anticipated the decision and simply flicked the switch. “It was as though someone had turned on the light. The system worked straight away in full operation and provided the desired results from the beginning,” says Secklehner, remembering this special moment.

INTERNATIONAL SHOWCASE PROJECT Just a few weeks after it had been commissioned, the new DeCONOx system had developed into a global showcase project. Large numbers of industry colleagues and scientists from all over the world come to visit the plant in Kirchdorf. Alois Hermandinger is delighted that enquiries are coming in from many other cement plants. “Scheuch was also awarded the Energy Globe Award for this innovative technology,” says Hermandinger, who is extremely proud of his company's idea. The new DeCONOx system from Scheuch is ahead of the industry standard and is setting new benchmarks in environmental technology.

FACT BOX: ▪ Simultaneous reduction of NOx, VOC and CO in one

system ▪ Low space requirements ▪ Low energy costs ▪ Low energy consumption through the use of waste heat ▪ Low maintenance requirements

Installing the new bag filter in strong winds at a height of 25 metres presented the assembly crew with significant challenges.

SCHEUCH DEMONSTRATES SOLUTION EXPERTISE HeidelbergCement, one of the world's biggest building materials companies, produces cement in the Czech municipal district of Radotín, Prague. The electrostatic precipitators at the Ceskomoravsky cement plant had to be replaced with bag filters in order to meet environmental standards. Scheuch was commissioned with this task and was confronted with the “problem child” of this historical plant in the form of its gas towers.

“The plant near Prague is an industrial gem. However, the conversion specifications from the plant management were anything but outdated – they were extremely challenging,” reports Georg Lechner, Sales Manager for the Industrial Minerals Industry division at Scheuch. “The order involved two elements. Each of the two dust extraction units has two components: a gas conditioning tower to cool and condition the gas so that it can be cleaned in the electrostatic precipitator afterwards, and then the electrostatic precipitator itself.

The plant near Prague is an industrial gem. Georg Lechner, Head of Sales Industrial Minerals

We were given the task of converting the electrostatic precipitators to bag filters one year after another. But the conditioning towers proved especially problematic. The inflow was very unfavourable, which led to a large amount of deposits and limited the function accordingly. To ensure that our bag filter systems could work at an

optimal rate, we had to find a solution. This was the only way of guaranteeing that the required specifications and performance values were met,” says Lechner, describing the situation.

SIMULATING THE FLOW OF THE REAL-LIFE PLANT To find the optimal inflow, Scheuch's flow specialists simulated the real-life plant. A solution was found which assured the desired improvement with relatively little mechanical reconstruction work. Once the concept had been developed on the computer, it was ultimately applied to the real-life plant. At the same time, the outdated spray lances were replaced with a modern bundle-head lance system together with a new pump station, pipework and control. This enabled the plant to meet the specification to reliably reduce the furnace exhaust gas to outlet temperatures below 130°C.

FIRST CONSTRUCTION STAGE COMPLETED SUCCESSFULLY

IN PROFILE GEORG LECHNER, Head of Sales, Industrial Minerals Georg Lechner knows Scheuch inside out, having worked for the company for over 20 years. The native Styrian studied machine construction at the Secondary Technical College (HTL) in Zeltweg, Austria. After completing military service, Lechner applied to Scheuch in 1991. He began in filter construction and later switched to sales. Lechner has been Head of Sales in the Industrial Minerals division (regional & international) since 1st September, 2015. It is not only Scheuch's customers who value his ability to explain extremely complex processes in a simple and understandable way. His colleagues also hold Georg Lechner in high regard as a trustworthy man who is always full of ideas. His innovative approaches are always in tune with the latest trends – whether he is introducing new sales activities or presenting the latest technology in the industrial minerals industry. He enjoys spending his free time hiking with his wife and three sons in Styria, Austria.

In the first construction stage, both gas conditioning towers and an electrostatic precipitator had to be converted simultaneously. Only 10 weeks were available for work on the electrostatic precipitator. The period of production downtime in which both gas conditioning towers had to be modernised was even shorter, with merely three weeks allotted. The tight schedule and additional behind-the-scenes “renovation work” presented the whole assembly crew with major challenges. “The team has accomplished a true masterpiece here,” Lechner enthuses. Around twelve employees were working on site. Working conditions were made even more difficult by the fact that the electrostatic precipitators had to be modified 25 metres above the ground and the strong winds often restricted work. “I would also like to thank the plant employees who actively supported us throughout the entire modification,” Lechner continues.

FULFILLING STRICT SPECIFICATIONS Not only the tight time specifications, but all the parameters that had been set by the Ceskomoravsky cement plant were fulfilled, some even exceeded. The second electrostatic precipitator is currently being modified. “Scheuch's turnkey strategy pays off when solving tricky cases. Very few manufacturers can offer everything from a single source. It is only through the cooperation of a good engineering team and an effective assembly team that we can solve such complex customer problems,” Lechner says confidently.

INDUSTRIAL MINERALS

FREE FROM MERCURY WITH XMERCURY To reduce mercury emissions, Scheuch has developed a technical innovation together with the company A-TEC and the W&P Group: the Xmercury split preheater system. The first system has been in operation for a year at the cement plant in Wietersdorf, Austria. The results are astonishing.

Mercury is a natural element and mainly occurs as a bound mineral. Due to its adverse effects on health, strict guidelines govern the use of mercury, especially in industry, trade and medicine. As traces of the heavy metal also occur in the rough stone used for cement production and in many fuels, A-TEC, W&P and Scheuch have joined forces to develop an especially efficient mercury reduction system.

RESEARCH PROJECT WITH AN INDUSTRIAL PLANT After an intensive development phase, construction of the first plant began in October 2014 as part of the unique process-integrated procedure. To achieve relevant airflow rates, the pilot system, which was developed in the context of a research project, was designed straight away as an industrial plant. After around half a year of construction, the new technology was ready to commence operation on the site of the Wietersdorf cement plant in April 2015.

BETTER HEAT BALANCE WITH AN INTEGRATED SYSTEM The great advantage of the new system lies in the integration of the procedure into the existing preheating process. During cement production, raw meal is ground in the raw mill and dried. Then the meal is put in the preheater tower. The thermal process causes volatile heavy metals to escape in gas form. These return to the raw mill in the gas stream. The mercury condenses as a result of the reduction in temperature and combines with dust particles. Until now, the isolated filter dust was fed back to the preheater tower. This meant that the concentration of mercury steadily increased with each cycle. The new Xmercury system interrupts the circulation of mercury in an innovative way.

INDUSTRIAL MINERALS

MERCURY SEPARATION IN PASSING STREAMS Georg Lechner, Head of Sales for the industrial minerals industry at Scheuch, explains the procedure: “The filter dust enters the split preheater. Put simply, this is a small preheating system. 3–4% of the hot gas from the lower part of the actual preheater is diverted at approx. 800°C and fed into the Xmercury system. There the filter dust is reheated, causing the mercury to escape.” The hot mercury-free dust is then separated in a high-performance cyclone and the newly developed hot gas filter. The dust is eventually guided to the main preheater tower and remains in the actual clinker burning process without losing any heat. The mercury-laden, dust-free gas is then quickly cooled with an injection of water to a final temperature of 100–120°C and the sorbent (e.g. activated carbon) is added, which binds to the mercury. A bag filter then separates the additive from the clean gas stream. When more sorbent is added to the process, it is enriched with an unusually high concentration of mercury. In turn, this ensures maximum usage of the sorbent and leads to extremely low consumption. As a result, the disposal volume of the enriched activated carbon is also very low. The mercury-laden sorbent can then be disposed of or treated. In this way, the isolated mercury is made available to the chemical industry.

SMALL SYSTEM, BIG IMPACT Florian Salzer, who is responsible for technology and development in the Wietersdorf cement plant, is delighted: “The system provided the predicted high degree of separation from the first time it was switched on. We are really happy with it.” Herbert Scheuringer from Scheuch provided some of the ideas for the project: “Before filtering the dust, you used to have to cool it down to a maximum of 250°C. We developed a hot gas filter for this system that withstands process temperatures of 500°C. We are sure that this filter will soon find an application in other sectors too. We are significantly improving the heat balance in mercury separation with the new Xmercury system and are also saving valuable fuels.”

FACT BOX: ▪ Up to 80% reduction in emissions ▪ Minimum costs for sorbent due to

low consumption ▪ Energy-saving system (no additional heat loss) ▪ Low gas quantity (3–10% of the total quantity) ▪ Process-integrated installation

Ultimately, an extremely high degree of separation can be achieved in the main kiln with the small Xmercury system.

ALL-INCLUSIVE SERVICE: THE KEY TO SUCCESS As a complete supplier, Scheuch proves its extensive expertise across all project phases – recently in two big orders in France and the Netherlands. With its innovative technologies, Scheuch has been supplying its customers with the key to success for more than 50 years. And that's not all: as a complete supplier, Scheuch is the one turning the key in the lock – by taking perfect care of each step of the process from planning right up to assembly. Scheuch was recently able to prove its turnkey expertise in two big projects which have just been put into operation. The Head of Sales, Klaus Emprechtinger and his team were responsible for the smooth implementation of both systems.

Precise planning, precise production, precise installation – this is what defines Scheuch's top quality. Klaus Emprechtinger, Head of Sales for the Energy & Metals industry at Scheuch

PERFECT IMPLEMENTATION FOR THE HIGHEST CUSTOMER DEMANDS Among Scheuch's most recent showcase projects is the implementation of a complete flue gas cleaning system in an existing combustion plant south of Paris. As part of the modernisation and adaptation to the new emissions guidelines, the company was responsible for supplying more than just two filter systems. As a turnkey supplier, Scheuch also took on the installation of an additive dosing system for the separation of acidic gases and heavy metals, including the supply of all components such as the pipework, insulation, as well as the cabling. The mechanical assembly and the integration of the flue gas cleaning system in the French end customer's existing system also required a high level of expertise and technical know-how. 15

The scope of delivery contained not just the two filter systems, but also the additive dosing system and all the additional components such as the pipework, insulation and cabling. Scheuch was also responsible for the assembly and integration of the flue gas cleaning system into the existing system. The entire turnkey project was managed by Scheuch's subsidiary in Paris.

Scheuch was able to meet the demands of this challenging scope of delivery thanks to its decades of experience and the perfect cooperation of the teams in Austria and France.

in the form of flue gas condensation. Using this type of system leads to a higher energy yield and therefore to higher efficiency, which in turn significantly increases the profitability of the complete plant.

The system solution was prepared with the customer in advance at a highly technical level. “A crucial factor in our success in projects of this size is precise planning,” explains Klaus Emprechtinger. “After we had analysed the customer's requests as precisely as possible, all subsequent steps were carried out to their full satisfaction.” The timely implementation of this project within just a few months was primarily down to Scheuch's well positioned French subsidiary, which is to be expanded in the future. Further orders on this scale are already on the horizon in France.

“Every project is unique in terms of the opportunities and hazards that it presents,” says Emprechtinger. “As a complete supplier for this project, we were responsible for delivering a complete turnkey plant on time which handled everything from economiser emissions to the chimney. Along with a strict adherence to the extremely demanding clean gas emissions requirements, a further challenge was to design all components in a way that would be suitable for installation in the tightest of spaces and then to carry out the installation with pinpoint precision.”

PRECISION IN THE TIGHTEST OF SPACES

Scheuch is able to develop solutions that inspire confidence even for the most demanding of customer requirements thanks to its comprehensive technical know-how. The importance of this wealth of expertise and experience becomes especially evident in the some times delicate assembly phase as well as during commissioning. “The fact that little to no fine-tuning is required after commissioning proves that perfection is a top priority at Scheuch,” reveals Emprechtinger. “Precise planning, precise production, precise installation – this is what defines Scheuch's top quality.” In combination with reliable project organisation, Scheuch is the perfect partner for challenging turnkey projects.

Scheuch also recently served as a complete supplier with distinctive all-round expertise for a Dutch project. “For this system, we provided everything that Scheuch's product range has to offer,” says Emprechtinger. The project also involved a piece of technology which was new for Scheuch in the biomass sector: “The dedusting plant was fitted with a filter including an additive dosing system. The innovation consists of a downstream catalyst system which reduces nitrogen oxides and NH3. This allows the customer to operate the plant with optimised costs and low pressure loss,” explains Emprechtinger. In addition, a heat recovery stage was implemented in order to use the latent and sensible energy contained in the flue gas 16

IN DEMAND: TURNKEY PROJECT IN FRANCE We spoke to Yoann Martchenko (COFELY) and Aurélie Burel (ENORIS) about the recently installed turnkey flue gas cleaning system in the south of Paris.

Why did you perform this upgrade? For technical, environmental and economic reasons, COFELY wanted to replace clean timber with old timber as this kind of wood is readily available around Paris. It actually has a better heating value, it focuses on energy efficiency, and is much more cost-efficient than woodchip. In addition, the heat produced by old timber is declared as renewable energy when it is recycled in a district heating grid, which reduces the value added tax in the heating price.

Why did you decide to work with Scheuch? In an extremely competitive field, Scheuch stood out from the other competitors with its expertise, experience and reliability – we knew that Scheuch would implement this project successfully from beginning to end. In the end, Scheuch turned out to be the perfect choice of partner due to their ability to adhere to the schedule, the professional manner in which they dealt with the complexity of the task and the project management in the Paris subsidiary.

Contracting out a turnkey project presumably requires a certain amount of trust? Definitely – the contract for this turnkey project is a clear vote of trust for Scheuch. And that trust has certainly paid off: despite the very demanding schedule, the Scheuch team has been able to meet all the deadlines on time.

IN PROFILE KLAUS EMPRECHTINGER, Head of Sales, Energy & Metals The new Head of Sales, Klaus Emprechtinger, on enjoying his job and the challenges of internationalisation. It is the tangible results that Klaus Emprechtinger values about his job. “To see a system that you have worked on for months finally installed in full size in front of you is confirmation of a successful project,” says the expert, explaining his enthusiasm. Emprechtinger has been a valued Scheuch employee for ten years now. As Head of Sales since summer 2015, he is responsible for the global energy and metals industries. His team also has an international focus – Emprechtinger works closely with company sites in Sweden, France and Germany, for example. For the passionate technician and father of two kids, an appreciation of staff members is just as important as this close cooperation with the field offices. “Among other values, Scheuch's company philosophy is based on solidarity, tolerance and a strong sense of unity. A strong team spirit is especially important to me when you consider the many staff members located on different company sites,” says Emprechtinger. “Everyone should affiliate oneself with Scheuch - here in Austria as well as in France and at all the other company sites. This allows us to remain true to our roots as a family-operated company even as the business grows, ensuring that our work is efficient and highly productive.”

METALS

METALS INDUSTRY RELIES ON SCHEUCH Whether there is little space for assembly or little time for implementation – it is challenges such as these that separate the wheat from the chaff. As a technology leader, at Scheuch these conditions are not seen as an obstacle but as an incentive. This is proved by two recent projects with voestalpine Stahl GmbH in Linz, Austria and Montanwerke Brixlegg, Austria.

voestalpine Stahl GmbH was looking for a replacement for an aging electrostatic precipitator in the sinter plant for iron ore agglomeration. Scheuch recommended two bag filters that could significantly increase suction capacity. Each of the two filters has a dedusting configuration of 340,000 m3 air per hour. Our partnership with Scheuch goes back many years. This project provides yet more evidence of good cooperation. Wolfgang Hennerbichler, Investment Project Management, voestalpine Stahl

As ore and coal dust is very abrasive, Scheuch opted for special wear protection in this case, which has already proved its worth in the industrial minerals sector. Around 400 tonnes of ore and coal pass over the conveyor belts in the sinter plant every hour. Using the new room dedusting system, one to three per cent of the material – up to twelve tonnes – can be recycled and fed into production again in the same period.

The tight space placed huge demands on the Scheuch assembly team. Nevertheless, years of experience and know-how ultimately ensured a smooth installation procedure.

INSTALLATION: A MOUNTAIN OF A TASK Installing both filters into the existing system was especially challenging. Space was extremely tight, which is why many large components had to be pre-assembled and then hauled to the correct location and position with a 500-tonne crane. The filter was placed in the system's electrical room to save space. Scheuch assembled the fan and chimney with a minimal footprint. Production was not jeopardised by the installation: both filters were connected during planned standstills, after which the sinter plant was able to continue normal operation. Wolfgang Hennerbichler of voestalpine Stahl (Investment Project Management) is extremely satisfied: “Our partnership with Scheuch goes back many years. This project provides yet more evidence of good cooperation.”

added to the converter if necessary. The energy costs for dedusting were reduced by around 30 percent due to a reduction in system pressure loss.

Scheuch also proved to be a competent problem solver during its project with the Montanwerke refinery in Brixlegg. Montanwerke's history in copper smelting spans over 500 years, and the refinery is now a leading recycling company for copper and precious metals.

During a five-week planned converter standstill, the new filter was assembled and put into operation. Montanwerke and Scheuch worked on this hand in hand: in the first two weeks the customer took care of demolishing the existing system and made preparations for the new one, including the construction of a concrete substructure.

A copper converter is used in the transformation of scrap metal into unwrought copper. The project involved replacing the existing 50-year-old filter system in the converter with a modern kiln deduster. This was no mean feat: kiln dust is very fine and does not flow freely. Emissions come out at a temperature of up to 600°C. In addition, the project had to be planned and implemented within four months.

GOOD ADVICE IS HALF THE BATTLE One of the priorities was consultation. By taking measurements over several days, the current situation was defined and a system concept was designed that was tailored exactly to the customer's requirements. The system was planned in such a way as to enable future expansion: this means a secondary suction system could be

The ball was in Scheuch's court for the remaining three weeks – and they complied with the tight schedule: the converter was able to resume operation on time. “Montanwerke Brixlegg now have a stateof-the-art filter system that will last for the next few decades,” says Franz Murauer, System and Process Technician at Scheuch.

IN PROFILE THOMAS KREUZHUBER, Head of Sales, Panels The native Austrian from the Innviertel region works all over the world and has sold Scheuch products for the wood-based panels industry on nearly every continent. His career began in November 2003 in field sales. During his years as Senior Sales Manager, the qualified business administrator was able to continually expand his wealth of experience. Last year he took another huge step up the career ladder: Since October 2015 he has held the position of Head of Sales for the wood-based panels industry. With a flair for the industry, his customer network now spans the entire globe. Thomas Kreuzhuber is especially valued for his reliability. His domain covers the entire spectrum of wet scrubber systems used for the cleaning of presses and dryer exhaust gas. As a depend able partner, he has rightly earned the complete trust of his customers and sales team. The high-flyer also aims high in his free time: he enjoys spending his time in the mountains and has undertaken numerous hikes in the last 20 years.

A CLEAN AFFAIR Since a SENA wet electrostatic precipitator was retrofitted in the drum dryer of the chipboard manufacturer Laminex in Dardanup, Western Australia, white smoke is literally rising from the chimneys.

When chipped wood is drying, the resulting flying ash, fine wood dust and aerosols – known as the “blue haze” – needs to be filtered out. For Laminex, situated 200 kilometres south of Perth in a popular holiday region, the challenge of finding a cleaner solution was especially great. After initial customer contact at the LIGNA trade fair in Hanover, Thomas Kreuzhuber, Head of Sales for the wood-based panels industry at Scheuch, got a good idea of the requirements on site in Dardanup. It quickly became clear to him that only a wet electrostatic precipitator would solve the problem. The dryer's cyclones cannot meet the required dust limit values. Bag filters and dry electrostatic precipitators are not suitable filter technologies due to the resins and wood dust contained in the gas.

Separation with a venturi wet scrubber would only work for a certain particle size and, in this gas composition, the particle size is much smaller. “At Scheuch, we see ourselves not only as sellers, but also as generators of ideas and as a partner for our customers,” explains Thomas Kreuzhuber. It took two years to clarify the technical matters, and the filter was tailored exactly to the customer's requests. The customer also viewed a reference plant in Europe in parallel. In the SENA wet electrostatic precipitator, the dryer exhaust gas leaves the dryer and is sprayed in the crude gas duct. After entering the filter, the gas is optimally distributed over an additional, permanently sprayed wet scrubber layer and is cleaned of any coarse particles. In an electrostatic filter stage operated with high voltage,

aerosols and dust are separated and clean gas will be emitted. SENA is normally a one-off investment due to its long service life. The filter is safe to operate, guarantees adherence to limit values and normally only needs to be cleaned once or twice per year. In addition, the customer was supported on site by Scheuch's experienced staff members during the filter assembly work. During the work, which took four months in this particular case, a supervisor was always on site. Scheuch staff members also monitored the correct operation in the first month after commissioning. From planning right up to commissioning and beyond – always a clean affair.

DEVICES AND COMPONENTS

SCHEUCH FANS: MOVING INSIDE Fans are truly indispensable components. They form the core of every emissions, extraction and dedusting system. They are also used in flue gas cleaning and compressed air conveyors. More than 50,000 radial fans have left the Scheuch factory since the company was founded in 1963 – and each of these was and still is precisely tailored to the customer's wishes and needs.

“At the beginning, we always carry out a precise analysis of the requirements that a fan must meet,” says Werner Pfifferling, head of the Components business unit. Details of the volumetric flow, pressure increase and the medium to be conveyed (clean gas, gas containing dust or material) determine the technical details of the fan, such as the shape of the impeller, the drive or the suction speed and impeller rotation speed, for example. Specialist technicians from Scheuch are on hand to evaluate this data and offer the customer advice – in order to achieve the ideal design with the best possible efficiency. The fan can be precisely adjusted to all customer requirements by the in-house construction department using software developed by Scheuch. In addition, the fan can be adapted to structural conditions.

THE COMPONENTS BUSINESS UNIT: The Devices and Components business has been established as an independent unit in the Scheuch Group since last year. The Components branch, under the leadership of Werner Pfifferling, is responsible for the project planning and sales of Scheuch's own components such as fans, discharge devices, compact filter units as well as Scheuch's control units. The target group comprises both international plant manufacturers and end customers from all over the globe. 22

DEVICES AND COMPONENTS

“Designing the fan correctly helps to keep invest ment and operating costs low,” says Pfifferling. A three-shift industrial enterprise can save 500 euros per year in electricity costs just by using 1 kW less energy. It is also worth remembering that a fan from the Scheuch factory has an above-average service life: some devices from the 1970s are still in use today. But time has not stood still at Scheuch: the in-house Research and Development department is constantly working on new developments, incorporating technical know-how gathered from five decades of plant manufacturing and practical experience. As a forerunner in environmental technology, it is important to the company that it continues to increase energy efficiency and improve general efficiency. The volume of patent applications filed by Scheuch shows that it is on the right track.

CFD simulations, for example, are used to calculate the ideal inflow and outflow of a fan, which has a positive effect on energy consumption and efficiency. Frequency converters control the speed of the fans – reducing the revolutions also limits the noise level and wear on the equipment. In general, we try to limit wear and tear as much as possible using special overlays, for example, which improve the resistance of the fans' impellers. A lot of energy also goes into developing heat-resistant fans: in the future, devices which work at more than 550°C (the current record temperature) will be available. Scheuch is also demonstrating its innovative strength by developing completely gas-tight fans used to transport hydrogen and other noble gases. If you take all these factors into account, it is hardly surprising that Scheuch's fans are extremely reliable and durable. If anything does need to be repaired or replaced once in a while, this will not take long at all: in-house production ensures that standard shafts or impellers can be produced within one day. Scheuch also takes care of assembly, training staff members and servicing. No fan is the same as another. In total, more than 2000 configurations are possible, ranging from those as small as a kennel right up to the size of a house, or, technically speaking, fans with a volumetric flow from 500 to 650,000 Bm3/h and pressure increases of up to 25,000 Pa. Fans can be used in many different fields: in the wood, wood-based panels, metals, industrial minerals and energy industries, as well as in the food, pharmaceutical and animal feed industries. Fans are also needed in industrial furnace construction, the glass industry and municipal vehicles. Scheuch has been supplying these industries reliably for more than 50 years.

A NEW HOME: SCHEUCH LIGNO HAS RELOCATED At the end of last year, Scheuch LIGNO GmbH's production department moved into its new home in Mehrnbach. The new site provides Scheuch's subsidiary with three times as much production space as there was at the main plant in Aurolzmünster. Space that is definitely needed: Scheuch LIGNO is making good progress barely a year after it was founded and is in a good position in terms of orders. “In our first year, we were able to score points with new, innovative products on the one hand and with an excellent, committed team on the other,” explains Alois Burgstaller, Managing Director of Scheuch LIGNO. The relocation went without a hitch and was completed in record time. There is now not only more space for production, but also significantly more room in the warehouse. At the same time, travelling distances are shorter, as, unlike on the original site, every thing is now packed into one location. The workshop, which is more than 4000 m2, mainly produces galvanized products. This includes LIGNO filters and LIGNO's pipe range, which consists of pipe and moulded parts, as well as duct parts. A new, modern coil cutting system with integrated duct and pipe production completes the production department.

LOGISTICS ENJOYS A NEW LEASE OF LIFE We are also proud of the newly acquired, company-owned vehicle fleet which includes three delivery trucks and trailers. Up until now, materials were always delivered by a forwarding agency and the assemblers travelled separately, which could be difficult to coordinate. There were sometimes incorrect deliveries and cases of customers having to store unnecessary material for long periods of time. Production now has the space that it needs to be able to work effectively. And the shorter distances mean that coordination between the departments is much easier. Alois Burgstaller, Managing Director, Scheuch LIGNO

Now things have changed. Florian Brandstätter, Head of Service at Scheuch LIGNO, explains the advantages: “With our own vehicle fleet, we can ensure that both the materials and the assemblers arrive at the customer's site at the same time. After the order has been completed, we take the remaining material back with us straight away and leave the construction site in a tidy state. All in all, we can react more quickly and be more cost-effective.” 24

ADVANTAGE WITH RESEARCH AND DEVELOPMENT Another advantage of the new location is the additional storage capacity, both under cover and out in the open. An area of over 4500 m2 is now available. The majority of the galvanized pipe part range is here in the warehouse and is immediately available for customers when needed. Especially interesting for customers is the in-house Research and Development division, in which materials and products are tested for their practicability. Devices such as extractors, chippers or sanding cabins are assembled on site and can be viewed by customers and sometimes tried out as well. “We effectively have our own small inhouse exhibition here,” says Managing Director Alois Burgstaller. Scheuch LIGNO's positive development is also reflected in the number of staff members: the Project Engineering and Service departments are expanding again with the aim of employing more than 100 people in total by early summer 2016. A core team of assemblers is supported by production staff members as and when required. The aim is to have all installations performed by our own personnel.

PARTNER FOR INDUSTRY AND HANDICRAFT Last year, Scheuch's former wood division joined forces with LBH GmbH from Wolfsegg to form Scheuch LIGNO GmbH. LIGNO is the perfect partner for customers from industry as well as those from the handicraft sector. The company supplies complete solutions for the fields of extraction technology, conveyor technology, surface technology, disposal technology, heating technology and control technology in the wood industry and other related sectors. Customers also benefit from the relocation of the production department and offices to Mehrnbach, as the communication distances are shorter, and procedures more flexible and therefore quicker. This is especially important in this sector of the market, as short delivery times are required.

IN PROFILE THOMAS LACHER, Head of Sales, Scheuch LIGNO After completing a course in machine construction at the Secondary Technical College (HTL) in Vöcklabruck, Austria, the native of Upper Austria joined Scheuch in 1992. He worked in project engineering for the wood industry for eight years before switching to sales. Last October, Lacher took up his position in the newly founded Scheuch LIGNO and shortly after became Head of Sales, bringing almost 25 years of experience at Scheuch to the role. He spends a lot of time working in the German-speaking countries and Russia, and has also visited Brazil several times on business trips. Thomas Lacher likes to work independently and values the freedom that his job at Scheuch affords him. He was born in the Hausruck viertel region of Austria and is married with two grown-up sons.

IN CLOSE CONTACT WITH CUSTOMERS Scheuch LIGNO GmbH's premiere at the BWS trade fair in Salzburg: Scheuch's former wood division made its first appearance as an independent company at the trade fair. Managing Director Alois Burgstaller and Head of Sales Thomas Lacher were delighted with how things went. Many of the 13,000 visitors paid a visit to LIGNO's exhibition stand and made the most of the opportunity to gather information and hold intensive technical discussions.

“We are very pleased with the response at our stand,” says Managing Director Alois Burgstaller, who, together with Head of Sales Thomas Lacher, spoke to over 200 visitors to the trade fair. “We noticed that people took a lot of time to gather information,” notes Lacher. And there was a lot to see: a complete dedusting system with deduster for indoor installation, chipper, silo discharge device, sanding table and sanding cabin made the LIGNO exhibition stand extremely eye-catching.

BACK TO SCHEUCH'S ROOTS As a leading trade fair for wood and wood crafts, BWS is an important platform for Scheuch LIGNO, which was founded last year. The fair features 250 exhibitors from ten countries. As well as maintaining existing customer relationships, many new contacts were also made. Staff members of the LBH GmbH sales team, which is now integrated into Scheuch LIGNO, were also at the fair and were able to meet their long-term customers. Following the merger with parts of LBH GmbH from Wolfsegg, Scheuch LIGNO now has a very broad structure. In previous years, the focus has been on cooperation with the industry; now Scheuch wants to remember its roots and give more attention to handicraft 26

and trade. As a result, the main aim at the trade fair was to develop contacts with smaller handicraft enterprises.

SPECIAL SOLUTIONS AND NEW PRODUCTS There was a great deal of interest in the swivelling workbench and the SEPAS 8000 flexible exhaust system with the compact and powerful 8000 m3/h dedusters. The special solutions that Scheuch LIGNO has developed for existing bricked silos also met with a lot of interest. “We are fulfilling current market requirements with our innovative products. And the many enquiries that we have received show that our product range is heading in the right direction,” says Alois Burgstaller. Scheuch LIGNO GmbH offers its customers complete solutions in extraction technology, conveyor technology, surface technology, disposal technology, heating technology and control technology. Everything comes from a single source – from consultation, to project planning and production right up to logistics, assembly, commissioning and services. “Structured in this way, we make the perfect, flexible partner for industry and handicraft,” explains Thomas Lacher.

THE CONTROL UNIT FOR PROCESS FILTERS MADE BY SCHEUCH It was the right decision 40 years ago to establish on-site development, production and testing of control units for filter systems. Having the right control unit is vital in order to ensure that the cleaning system for separating dust particles will operate efficiently. We incorporate our engineers' comprehensive expertise on filter cleaning, the information exchanged between the individual internal departments and also the information resulting from applications in various fields into the development of our control units at Scheuch.

PULSEMASTER PREMIUM – THE PREMIUM CLASS OF CONTROL UNITS The high-end filter control unit “PulseMaster Premium” was specially developed to meet the cleaning control requirements of large line and chamber filters with EMC technology up to 2.5 million Bm³/h. Depending on the operating mode (EMC technology, offline, online) and on the overall customer-specific process, the latest-generation filter control unit ensures the best possible customised cleaning of the filter system.

THE BEST SYSTEM AVAILABILITY THANKS TO INNOVATIVE SAFETY EQUIPMENT An integrated emergency program ensures exceptional operational safety. Individual chamber modules switch to automatic operation if necessary. In this mode, the relevant module takes on the function of cleaning control. A further feature of the PulseMaster Premium is that data can be exchanged easily by integrating the control unit into

the customer's central control systems using a fieldbus interface (ProfibusDP, DeviceNet, ProfiNet, Ethernet/IP). Specially developed for the cleaning control of process filters, the PulseMaster Premium ensures the best possible customised cleaning in different operating modes. The integration of sensors into the filter means that process-specific values such as temperature, volumetric gas flow and pressure are continuously measured in order to set the optimal filter operating point. This means that, even under fluctuating operational conditions, the required cleaning pressure can be set automatically, thus reducing operating costs.

THE PULSEMASTER PREMIUM STANDS FOR: ▪ Excellent operational safety and system availability ▪ Easy maintenance and commissioning ▪ Low operating costs ▪ Intuitive operation with logical menu navigation ▪ Data exchange via standard fieldbus interfaces

SMC: THE FUTURE OF COMPACT BAG FILTER TECHNOLOGY With the newly developed IMPULS-Filter with a horizontal flat bag design, Scheuch is offering the perfect fine and super-fine dust exhaust system for use in production halls with limited space. The compact system design, quick assembly and efficient performance of the Space Minimizing Concept (SMC) promise tangible benefits during daily operation.

INNOVATION

HIGHEST SEPARATION PERFORMANCE ACCORDING TO INDUSTRIAL STANDARDS After around 22 months of development time, Scheuch is setting a new benchmark where fine dust extraction is concerned with the Space Minimizing Concept (SMC). Known until now for high-quality devices with vertical arrangement of the filter bags, Scheuch's new system provides key benefits for the specific demands of fine dust in the metal processing industry, for example. The horizontal filter bags and the top-down exhaust air current achieve a significantly improved filter surface load and separation performance. Tried-and-tested Scheuch technologies are employed for this purpose, such as the typical twin-nozzle arrangement and the control. For the first time, the optimised pressure tanks with integrated valves are also being put to use – this leads to a cleaning system with maximum performance.

INNOVATION THAT REAPS REWARDS The new IMPULS-Filter is the first product with new technology which was designed at Scheuch by a core team of experts in Process Technology and Product Development in close cooperation with the Production and Assembly department. A fundamental aspect is the adherence to a consistently low differential pressure even with the most difficult dust. During the test phase, further optimisation was undertaken to guarantee the best possible operational safety. The result is an especially

CORROSION PROTECTION IN ACCORDANCE WITH THE LATEST STANDARDS For a long time, the subject of corrosion protection for steel structures has only been considered superficially. The internationalisation of the markets and the multitude of individual requirements have brought about a proliferation of application variants and a vast pricing structure. New certification according to EN 1090 and EN ISO 12944 is now setting binding quality standards and enabling maximum transparency when calculating costs.

CERTIFIED QUALITY: ADDED VALUE WITHOUT ADDED COSTS With the implementation of the new standards, precise guidelines are being defined for corrosion protection and the necessary application quality in all relevant areas – from pre-treatment and surface preparation (achieving the necessary roughness depth) right up to the actual primer, undercoat and top coat. The requirements are based on different categories of prolonged exposure to corrosion (C2–C5), which are in turn defined according to several central criteria. These primarily include the location of the structure to be protected (indoor or outdoor), the intended period of usage (2–5, 5–10 or 10–15 years) and the properties of the sub stances responsible for the corrosion (smoke emissions, air humidity, atmospheric salinity, etc.). 30

To ensure that components maintain as much of their value as possible, it is best to work with clear standards with regard to corrosion protection – and this is exactly what we can guarantee our customers with this certification. Christopher Stockenhuber, Team Leader Surface Treatment

The certification in accordance with EN 1090 and EN ISO 12944, which is checked annually by accredited organisations such as the TÜV, is not only advantageous for the company in question but also primarily for the customer. Application of corrosion protection in accordance with defined quality standards ensures safety and a clear definition of specifications, without incurring any additional costs in comparison to uncertified implementation.

INNOVATION

EMPLOYING EXPERTISE RATHER THAN GUESSWORK As a certified company, Scheuch will not only apply corrosion protection in the most suitable quality for each order, but will also ensure absolute cost transparency and safety. This begins with the systems (the company recently invested in a new sand blasting system) and covers the relevant procedures right up to ensuring that personnel is certified. It also applies to the pricing, which is structured in five clearly defined classes and is based on the optimum method of application in each case. This prevents the risk of undercoating or overcoating and the resulting added costs. Scheuch has made every effort to secure its position as a forerunner in the field of corrosion protection, having spent over three years preparing for the certification. The result is quality arising from expertise you can trust.
