Voith has developed a new generation of sensors with regards to availability, reliability and maintenance handling. As the main components of the Quality Measurement System, the sensors measure the most important quality parameters of the paper being produced, such as basis weight, moisture, caliper and ash. The Quality Control System reduces as much as possible the variability in machine direction (MD) and cross direction (CD). This allows paper manufacturers to move quality targets in the most profitable operational zones – for example to maximize the moisture content of the paper.

  • Higher product quality due to modular and fully independent sensors with optimized housings and integrated temperature stabilization
  • Increased reliability and availability of the MD-Controls
  • Delivering more power within smaller and lighter sensors that require less machine space
  • Minimized maintenance effort through new plug & play standards

Higher product quality due to modular and fully independent sensors with optimized housings and integrated temperature stabilization
The sensors and components are designed to operate in challenging environments under harsh conditions of the paper mill. Special, high-temperature housing options are no longer needed. The new temperature-stabilized housings are designed for ambient temperatures up to 100° C / 212° F.

The new sensor generation features a compact, lightweight design and increases the reliability and availability of the machine direction controls.The new sensor generation features a compact, lightweight design and increases the reliability and availability of the machine direction controls.

Increased reliability and availability of the machine direction controls
A distinctive feature of Voith’s control concept are the machine direction controls based on physical models of the paper machine. Voith’s supervisory controls replicate the physical behavior of the process. The controls manage even high-frequent process disturbances. They also effectively reduce the time for grade changes and therefore minimize production losses.

Delivering more power within smaller and lighter sensors
The new sensor slots have been optimized in their width from 13 cm to 7.5 cm, which leads to smaller and lighter sensor packages, allowing more sensors to be installed in the available machine space.

Minimized maintenance effort with new plug & play principle
The heart of the new sensors is a processor board that provides precise and fast signal and data processing. Sensor features are easy expandable via firmware upgrades. Configurations and calibration parameters are stored inside the sensor and can be changed remotely. Furthermore, the new plug & play functionality reduces complexity in maintenance.

Papierfabrik August Koehler SE has engaged Voith to comprehensively modernize the PM 5 paper machine at its main paper mill in Oberkirch. This vote of confidence in Voith is further evidence of the long-standing successful business relationship between the two companies.

  • SpeedSizer AT improves competitiveness and increases flexibility
  • Fewer downtimes and web breaks 
  • Contactless high-performance qDryPro Compact dryer increases efficiency
  • Upgrade to pave the way for future speed increase and second expansion phase

Voith worked with Koehler to develop a customized concept for the PM 5 that improves competitiveness and increases flexibility. Downtimes and web breaks will be reduced and efficiency increased. The upgrade with high-tech components will allow paper coated on both sides to be produced in a larger operating window in future. The paper machine is also being prepared for a speed increase in a possible second expansion phase.

To achieve these ambitious project goals and improve the customer’s competitiveness, Voith’s upgrade incorporates the applicator unit SpeedSizer AT, which is ideal for fast running paper machines, the energy efficient, contactless high-performance dryer qDryPro Compact, and the PrevoSystem for short and reliable threading. For the pulpers in the press and reeling section, new pulping units are to be installed for even more effective pulping of the broke.

Voith PM 5 August Koehler SE Oberkirch, Germany.Voith PM 5 August Koehler SE Oberkirch, Germany.

“The main reasons for upgrading our PM 5 are to increase efficiency, improve flexibility to allow a wider range of paper grades, and reduce costs.”, says Hartmut Felsch, Mill and Division Director Oberkirch at August Koehler SE.

SpeedSizer AT: Optimum film application at all times
SpeedSizer AT enables uniform, flawless application of sizing and coating films and improves paper qualities, penetration and surface coverage. The carbon fiber support beam is dimensionally stable regardless of external temperature fluctuations. It maintains maximum straightness and allows uniform film application over the entire operating period. The doctor rod holder used will be the patented modular system SpeedRod M, in which doctor rod, doctor bed, pressure hose and clamp hose are integrated in one component. Any type and diameter of doctor rod can be selected without necessitating laborious machine adjustments. Because individual components can be replaced, malfunctions can be fixed quickly and easily, downtimes reduced and production losses minimized. The SpeedSizer AT has already proven effective in more than 300 customer installations.

qDryPro Compact: Energy efficient, contactless high-performance drying
The qDryPro Compact is a high-performance dryer for paper and board grades with single or double-sided coating. There is usually very little space available for paper machine upgrades. This is why the air system of the qDryPro Compact was designed to be especially space-saving. The air circulation fan is integrated into the dryer. The combination of infrared and hot air drying is extremely energy efficient, because it uses only the waste heat from the infrared heaters to heat the air hood.

PrevoSystem: Reliable and short threading processes
Voith’s scope of supply also features the Prevo threading and cutting system including the PrevoThread C vacuum threading belt and a PrevoCut DTC double tail cutter. Because an inefficient threading process can stop production for up to an hour for every web break and restart, Voith developed the fully automated PrevoSystem, which ensures reliable threading processes and short threading times. It reduces production losses after every web break and increases productivity. 1,000 Prevo solutions installed worldwide testify to its benefits.

About the Koehler Paper Group
With a history that goes back some 210 years and a turnover of around EUR 900 million, the Koehler Paper Group is one of the few independent family-owned German companies in the paper industry.

At its headquarters in Oberkirch and paper mills in Kehl, Greiz and Weisenbach, its workforce of 1,850 people uses cutting-edge technology to produce more than 500,000 metric tons a year of specialty papers and board for the worldwide market.

Ilim Group, Russia's largest pulp and paper producer with an annual production volume of more than three million tons, will significantly expand its production capacity in a project now underway. As part of an extensive investment program, the company plans to produce up to 600,000 tons of kraftliner per year at its new plant in Ust-Ilimsk, Eastern Siberia, starting in 2021. The key partner in this project is the technology group Voith, which is working with Ilim Group on this scale for the first time.

  • Production of up to 600,000 tons of kraftliner per year
  • Project scope includes two BlueLine refining lines, one XcelLine system, drive components, comprehensive training measures and the Process Line Package (PLP)
  • Integrated Papermaking 4.0 components increase efficiency, product quality and machine availability

As part of the Process Line Package (PLP), Voith assumes full responsibility for the project. The experts for the entire papermaking process ensure that the plant in Siberia starts up safely, on schedule and with precisely coordinated components. The PLP reduces the number of required interfaces and contact persons and simplifies the entire project handling, which ultimately also reduces costs.

As a full-line supplier, Voith is able to provide all system components including screens for each section, as well as comprehensive Papermaking 4.0 digitizing technologies. In addition, the globally positioned group is responsible for the electrical equipment and the entire drive system of the plant. A comprehensive training program on the new machine is also part of the project scope.

With XcelLine paper machines, Voith offers efficient paper production of every paper grade on a new level.With XcelLine paper machines, Voith offers efficient paper production of every paper grade on a new level.

“Voith is partnering with Ilim Group in this historical and outstanding project. It will become a milestone for the Russian pulp and paper industry, and we are proud to contribute with our deep experience and latest innovations,” says Christoph Müller-Mederer, President Projects EMEA at Voith Paper.

The centerpiece of PM 1 in Ust-Ilimsk is a XcelLine of the latest generation. With a wire width of 10,300 millimeters, the Ilim Group plans to produce up to 2,150 tons of kraftliner per day with basis weights between 80 and 175 grams per square meter. This will make the new machine the most powerful of its kind in the world. The production speed of 1,200 meters per minute also represents a top performance.

OnCare.Health and OnCare.Asset as well as OnEfficiency.Strength are among Voith’s Papermaking 4.0 digitalization technologies that ensure consistently high product quality and reliably efficient manufacturing. In Ust-Ilimsk, OnCare.Health monitors the current status of the system at all times, registers even the smallest malfunctions and their causes, alerts the papermaker and independently works out optimization measures. In combination with the intelligent maintenance management system OnCare.Asset, this enables a significant increase in machine availability.

In addition to the record-breaking XcelLine machine, two BlueLine stock preparation systems are also included – one for hardwood pulp, the other for softwood pulp. They ensure exact compliance with the composition of the pulp. Voith's technology thus sets the course for maximum product quality right from the start of the process.

The preassembled equipment will be erected directly at the construction site in Ust-Ilimsk. In addition to the XcelLine and the BlueLine, components supplied by Voith will include a FlowJec dosing system for additives, the former section with two Fourdrinier machines equipped with MasterJet Pro F, a ModuleJet II and DuoShake, EcoCal hard calender, the drying section with CombiDuoRun dryers and a Sirius reel with EcoChange and VariFlex Performance winder. The delivery of the 79-ton Nipco-P roll represents a particular challenge for the project.

“Ilim sees its leadership role not only as the largest pulp and paper product manufacturer, but also as an investor into state-of-the-art innovative technologies. This investment decision was based on impressive results demonstrated by Ilim Group in the Asian market”, said Xenia Sosnina, General Director of Ilim Group. “We know this market well and see its opportunities. The contract we have signed is one of the largest contracts in the history of the Russian pulp and paper industry. Voith Paper, a leading manufacturer of paper and board machines with the highest level of automation and digitalization, has become our partner under this project. Our project will be one of the most advanced high-tech projects in the global pulp and paper industry, and will provide the Asian market with the volumes of high quality products it demands.”

With its new gas-fired HelioX infrared emitter, Voith is offering a particularly efficient solution for contactless drying along with impressively low emissions. Not only can the new emitter be used to increase productivity, the reduced fire risk also improves safety in paper production.

  • Productivity increase thanks to output of up to 14 kW
  • Gas consumption and emission values considerably reduced
  • Reduced fire risk in the event of web breaks for improved safety

The new infrared emitter HelioX promises to deliver higher productivity with lower emissions and a reduced fire risk.The new infrared emitter HelioX promises to deliver higher productivity with lower emissions and a reduced fire risk.

The key component of the new HelioX infrared emitter is its incandescent body, which has a highly efficient ceramic structure with a notably large surface area. The special geometry ensures improved combustion, resulting in both higher drying efficiency and a 50 percent reduction in nitrogen oxide (NOx) and carbon monoxide (CO) emissions. These low emission values are becoming increasingly important in view of the German air pollution control regulations (TA Luft) and more stringent emission limits in various countries, so as to obtain long-term operating approvals.

The HelioX infrared emitter is designed for an output of 14 kW. Consequently, it achieves a better drying efficiency, which enables higher machine speeds and more flexibility to produce different paper grades, and as a result, increases the productivity of the plant. With up to 10 percent better efficiency, the emitter also leads to lower gas consumption, lower running costs and a reduced CO2 footprint. Because of the low mass of the incandescent body, the HelioX infrared emitter offers a particularly fast heating up and cooling down time. This improves safety in production, as there is a much lower risk of fire in the event of web breaks. This means that the operating risk is also reduced, and shorter downtimes can be expected.

The design and highly efficient ceramic surface structure of the incandescent body ensure very homogeneous heat transfer, so that a maximum of energy is converted to infrared radiation.The design and highly efficient ceramic surface structure of the incandescent body ensure very homogeneous heat transfer, so that a maximum of energy is converted to infrared radiation.

The gas-fired HelioX infrared emitter is now available. It can be used for contactless drying in any Voith paper machine and also in those of other manufacturers. It is also possible to use in other areas of application such as drying fiberglass mats or technical textiles.

Increasing production capacity by over 90 percent and switching to more economic raw materials while increasing cleanliness of the end products – these were the two goals of the Serbian paper manufacturer Umka d.o.o. when upgrading its cardboard machine BM1. Part of the project was thereby an upgrade of the stock preparation with an InjectaCell Compact flotation unit and InfiltraDiscfilter disc filter from Voith’s BlueLine portfolio. Due to the excellent performance of the new products, the company has laid the groundwork to achieve these goals.

  • Compact flotation – minimum space requirement and excellent technological results
  • Robust disc filters with wide operating window

The whole rebuild project was part of Umka’s initiative to expand its production from approximately 105,000 metric tons of cardboard per year to more than 200,000 metric tons. Until that time, Umka has supplied 30 European countries with cardboard in three quality grades. The increased capacity gives the company, founded in 1939, the opportunity to tap into other markets.

On the lookout for cost-effective raw materials
During the rebuild, not only was the capacity on the agenda, but so too was the quality of the raw materials. The demand for the bright white recovered paper used by Umka had increased significantly in recent years. Also, it was becoming more and more difficult to buy raw material, and prices were continuously rising. Plant operators were therefore setting their sights increasingly on more cost-effective raw materials such as newspaper and magazine paper, which were available on the market in sufficient quantities. However, the technology required to process such raw material grades is considerably more advanced compared to conventional approaches. Investing in a new stock preparation system was therefore an important first step toward implementing the corporate strategy. “Previously, we worked with one loop and without a flotation system, but the planned changes were inconceivable with this arrangement. Our long-term goals could only be realized by integrating a flotation unit into a second loop,” explains Dragoslav Nešković, Project Leader at Umka.

The Voith team’s first task was to extend the existing stock preparation to deal with the new challenges, like reliably removing contaminants such as inks, stickies and glue from the paper suspension. To increase storage capacity of the stock preparation and to separate water loops from paper machine for improved paper machine performance, a disc filter was installed.

Compact flotation – minimum space requirement and excellent technological results
As a smart solution to effectively integrate the new machines into the existing building, Umka selected the InjectaCell Compact flotation unit ICC2/44 in combination with InfiltraDiscfilter IDF370. The new compact flotation system from Voith’s BlueLine range is based on InjectaCell (ICC) technology. It saves up to 50 percent energy compared to Voith’s famous EcoCell, which was the standard until 2012.

Schematic drawing of the InjectaCell Compact flotation systemSchematic drawing of the InjectaCell Compact flotation system

In InjectaCell Compact, secondary flotation cells are omitted. The first primary cells take over their task in addition to their normal duty. Due to this combined function, they are called fiber recovery (FR) cells. The foam from the consecutive primary cells is re-aerated by special injectors in these fiber recovery cells, thus maintaining the yield on an excellent level. A further important aspect of the InjectaCell Compact is the InjectaPump (ICP). InjectaPump is a combination of foam destroyer and pump that brings the foam from the primary cells to the fiber recovery injectors. As this is installed close to the flotation cells and no foam tank is needed any more, the whole InjectaCell Compact unit can be mounted on one floor.

The essential components of the flotation unit date back to the late 1960s. Profound knowledge in the properties of deinking foam and customer needs led to the development of this unique concept of fiber recovery cells. “The compact flotation technology is quite new. However, the feedback from all customers which operate InjectaCell Compact has always been very positive,” Dr. Antje Voiron from Voith points out. Despite their compact design, the quality of the results is comparable to that of conventional two-stage flotation systems. Thanks to the innovative technology, Umka can produce a fiber suspension with precisely the properties that the company requires for its products.

Robust disc filters with wide operating window
The wide range of raw materials and the successive increase of the production by more than 40 percent were also special challenges in this project. Thanks to the robustness of InfiltraDiscfilter, it can accommodate broad production ranges and varying freeness of the used furnish. In conventional filters using polypropylene (PP) filter bags, such conditions need extremely close operator attention in order to avoid damage of the PP bags. The BaglessPlus discs take such variations easy. Its design is based on many years of experience with over 500 installed filter discs. Their unique bagless technology makes the InfiltraDiscfilters robust and reliable – two characteristics that are most wanted in the paper industry.

Both InfiltraDiscfilter and InjectaCell Compact have proven to be highly reliable, simple to operate and virtually maintenance-free. The operating costs, which are lower compared to conventional technologies, were a further argument for Umka to decide to work with Voith stock preparation equipment again after many years.

The board machine currently produces about 130,000 metric tons of paper, and Umka is already taking a positive view: “The performance of the InjectaCell Compact and the InfiltraDiscfilters has fully met our expectations. Our employees also appreciate the easy operation and reliability of Voith products,” says Dragoslav Nešković, Project Leader at Umka.
