Editorial Issue 25

With Heart and Soul: Focusing on People

The service company NEAC Compressor Service has played a key role within the NEA GROUP for 25 years. Two important events prepared the ground for this successful development. By additionally purchasing the Halberg product line in 1977, NEUMAN & ESSER managed to re-enter the field of large reciprocating compressor construction. Moreover, the Halberg brand was the first of a total of eleven legacies which were to follow up until today. The second important event was the foundation of NEUMAN & ESSER Customer Service and Sales Company and the resulting separation of aftermarket and new machines business in 1983. During the first ten years, starting in 1988, NEAC was a joint venture with Atlas Copco. The global sales network provided by the large partner enabled us to move directly into international business. The clear split between aftermarket and new machines business provided both greater transparency and a clear focus on the company divisions. It became apparent at an early stage that the NEAC employees are the representatives of the company – it depends on the people!

Quality, innovative technology and the reliability of the product form the basic prerequisites for survival within a market. Therefore we have invested intensely in the global infrastructure in the past: in measurement technology, health & safety measures as well as tools, also for information and data processing.

In addition to technical equipment, know-how and experience is important to the employees. Many of them remain a "Neuman" for the rest of their lives – our customers also benefit from this as they can always rely on their contact person.

The competence at our worldwide locations forms the decisive criterion for successful cooperation with the customer. We wish to be and remain the reliable partner – both for our customers and employees. As a family company, we value partnership on a long-term basis and will continue to invest in the development of local competence. Read more about the formation of NEAC and the opportunities which have arisen from it for NEUMAN & ESSER.

NEAC Compressor Service

The Competent, Visionary OEM Service Provider

After 25 years’ customer service, the “jubilarian” NEAC Compressor Service can look back on a history of success which is equally eventful and multifaceted. It is not only that the Service Division has developed to become a supporting pillar of the NEA GROUP since 1983 with its separation from operative new machines business, but also that NEAC Compressor Service has become established within the market as an OEM Service Company with a global network of ten Service Centers. The foundation of NEAC Compressor Service in April 1988 as a Joint Venture with Atlas Copco took place during a tumultuous period of consolidation, during which large suppliers concentrated on turbo compressors as a result of changes within the market and discarded reciprocating compressors as excess capacity – the suitable platform for NEA Holding, to incorporate “stranded” reciprocating compressors as licenses and the transfer of aftermarket maintenance of these machines to NEAC Compressor Service. Today there are eleven, chronologically listed in the order of acquisition: NEA, Halberg, Linde, KSB, Erhardt & Sehmer, Demag, Mafa Wurzen, Chicago Pneumatic, GHH Esslinger high pressure compressors, Borsig for the former reciprocating compressor series built in Berlin until 1995 and finally Penn Process Compressors. NEAC has ample breathing space to incorporate further licenses.

What can a customer expect from a Service Company with an OEM profile such as NEAC Compressor Service? This question was intensely discussed with compressor system operators at the NEAC company anniversary symposium on June 4, 2013. If Chemical and Petrochemical companies incorporate the “total cost of ownership” concept in their assessment, it is also financially worthwhile to commission OEM specialists. Who is not interested in the up to 80-year-old compressors working unrestrictedly and providing their full output? Bernd Wagner, NEAC Compressor Service Managing Director, could not express it more fittingly: “When compressors are “young”, they can also be maintained in-house and parts which “almost” fit can be built-in. However, if this happens repeatedly over a longer period, the customer loses the connection to the original state of his compressor. If ad-hoc repairs then result in unsatisfactory meantime between maintenance, only an OEM is able to assess the differences to how it should be and return the compressor to its original state. The original documents, experience and knowledge of the machine as well as technical resources necessary for it are exclusively within an OEM’s scope!“

Service intervention or an overhaul, preferably as part of a service contract with NEAC, becomes a predictable factor, for example for Air Liquide in Antwerp. Even better, they primarily value 24/7 availability, flexibility during interventions and overhauls and, above all, the certainty that wear parts based on the running behavior are continuously improved with the latest design or material matrix. Why is this global market leader for technical gases prepared to pay a premium for an OEM? Machine outages are a sensitive factor which costs a great deal of money in production losses. The customer expects a quantifiable improvement in reliability from an OEM, including, for example, a longer guarantee period and commercially more attractive terms.

With a portfolio of some 5,000 compressors to maintain worldwide, irrespective of the brand, NEAC Compressor Service is currently preparing for its next challenge: consolidation. On the one hand, this refers to the consolidation of the structures of the global NEAC Centers, enabling each location to develop to a competence center with the leading know-how. The establishment of worldwide Repair Coordination Centers was an initial important step towards achieving this. However, on the other hand it is also important to summarize the multitude of machine data. Especially for this purpose, NEAC has developed a web-based platform for the servicing and spare parts activities for a machine during its lifetime. The technical documentation such as operating instructions, parts lists, service reports, reconstruction and complaints information is also stored there; in short the full life documentation and status for every machine. This enables the reconstruction of every single change to the machine, no matter how small its scope is. This enables NEAC Compressor Service to fulfill its mission of “Passion for Detail” in hardware and in software.

25 Years' NEAC

Back to the Future: Special Event for the Company's Anniversary

The symposium for reciprocating compressor operators for which NEAC Compressor Service had sent out invitations on the occasion of the company’s 25th company anniversary held a program with “lively” contributions in store for the 150 invited guests. Therefore part of the works premises was transformed into a show stage with an Atrium and an OEM exhibition park for June 4, 2013, thus enabling the staging of the anniversary’s leitmotif “25 Years’ NEAC – Back to the Future” accordingly.

The leitmotif and its significance for NEAC but also for the entire NEA GROUP were made clear by the Managing Partners Stefanie and Alexander Peters in their welcoming speeches, thus providing a clever transition to the next program item: a panel discussion with the protagonists from the moment of NEAC’s foundation, with Klaus Peters and André Schmitz, now both senior consultants for the NEA GROUP and respectively Atlas Copco, as well as Bernd Wagner, today’s NEAC Compressor Service Managing Director. It was chaired by Martina Frenz, Head of Corporate Communications. She took the listeners on a journey through time using targeted questioning techniques to the attendees, a journey which imparted an insight into the eventful phase of the “reciprocating compressor renaissance” during the 1980s and 1990s and at the same time in the step-by-step development of NEAC Compressor Service to an OEM specialist.

During the spot landing of explanations in the present, Johan Klipper, Regional Maintenance Manager and Dirk van Roosbroeck, Purchase Manager Benelux Centre, two experienced experts from Air Liquide from Antwerp, Belgium, were incorporated into the discussions. They showed what criteria are important for the selection of service providers and the critical point where a change can even become a test of courage. During the ensuing lively discussion, all participants agreed that the “total cost of ownership” determines the quality of service assignments.

»The original documents, experience and knowledge of the machine as well as technical resources necessary for it are exclusively within an OEM's scope!«

The fact that sometimes a few hundredths of millimeters can be decisive for a professional service assignment was proven by the NEAC engineers Harry Lankenau, Engineering Manager, Stefan Damberg, Project Manager as well as Ilya Asser, Sales Manager East Europe in their technical presentation of the wide range of calculation and measurement techniques. The participants followed the live demonstration of object scanning on a cylinder – an innovative technique for measuring surfaces which will decisively influence NEAC’s digital future – with amazement, whereas the numerous exhibits in the OEM exhibition park were able to show more history than innovation. However the means of showing the eleven licenses really brought both the tradition and technology of these “old treasures” back to life. Not only the NEAC staff presentations from headquarters but also NEAC Managing Director Claudio Corea and know-how carrier Bruno Correa from Brazil as well as Brian Bertelsen with Richard Frischgesell from the USA rendered a substantial contribution, arriving from afar. Thus, the less well-known brands Demag, CP, and PPC were also seen in a special light. Only an OEM service provider, living in the structures of “unfamiliar” worlds, simultaneously and consequently following the desire to maintain passion for even the smallest of details, is in the position to build this bridge. This is at least proven by the numerous personal congratulations and entries in the guest book which Bernd Wagner and his team were very happily allowed to accept and which strengthen them in their policy.

Power to the People

Audi Installs the World's First Industrial Plant Using Power-to-Gas Technology

NEUMAN & ESSER delivered three compressors for one of the currently most exciting and promising future projects. The Audi e-gas plant is designed to manufacture about 1,000 metric tons (1,102 US tons) of synthetic renewable methane per year. For this purpose, the NEA compressors assume various tasks.

Highly efficient storage media is urgently needed for wind power and photovoltaics. Fluctuations caused by weather and seasonal variance can only be compensated using such storage. The power-to-gas concept which stores and transports regenerative energy as hydrogen or methane is promising. Using this, these renewable resources can be made optimally useable and fossil sources can be replaced reliably.

The world’s first industrial plant for generating synthetic methane (e-gas) from CO2 and renewable electricity is under construction in Werlte, Germany. It draws electricity primarily when an excess is available. “This power-to-gas technology opens up new possibilities for sustainable mobility and tomorrow’s energy industry. The e-gas project marks a transition toward alternative forms of energy for automobiles,” explains Reiner Mangold, Head of Sustainable Product Development at AUDI AG.



»This power-to-gas technology opens up new possibilities for sustainable mobility and tomorrow’s energy industry.«

The Audi e-gas plant, which can convert six megawatts of input power, will utilize renewable electricity for electrolysis. This process splits water molecules into oxygen and hydrogen, which could one day power fuelcell vehicles. Because there is not yet a widespread hydrogen infrastructure, however, a second process step follows: the hydrogen is then reacted with CO2 in a methanation unit to generate renewable synthetic methane.

CO2 required for the e-gas production is a waste product from a nearby biogas plant operated by the energy provider EWE AG. The biogas plant is fed with organic waste as opposed to energy crops, avoiding any competition with food production. The e-gas plant will produce about 1,000 metric tons (1,102 US tons) of e-gas p.a. and chemically bind some 2,800 metric tons (3,086 US tons) of CO2.

The Audi e-gas plant in Werlte is being built on a site owned by energy provider EWE AG measuring 4,100 m² (44,132 sq ft) overall. Ground was broken in September 2012. As the owner, Audi is constructing the plant in cooperation with the equipment manufacturer etogas GmbH (formerly SolarFuel GmbH).

Three NEUMAN & ESSER systems are part of it all. The vertical e-gas compressor 2TZS25GT is new in NEA’s range and supplies 350 Nm³/h. The 2-crank and 2-stage machine is a pressure-resistant supplement for low volumes. A V-type biogas compressor has a supply quantity of 700 Nm³/h. The second V-type compressor with 1050 Nm³/h can compress both e-gas and biogas. The NEA compressors are on the one hand involved in feeding the processed biogas and on the other hand when passing the renewable methane on.

EWE has already cooperated with NEUMAN & ESSER for several years. Initially, NEA supplied the energy company large boxer compressors for natural gas storage. As the biogas sector developed, EWE inquired regarding compressors for feeding in the high pressure area more and more frequently. EWE has a reliable partner with NEUMAN & ESSER.

NEAC Compressor Service purchased a “Biogas Caddy” two years ago for servicing existing systems. The proven specialist Dirk Rühlmann has everything together that he needs for his daily work here because often enough the plants are a long way away from the next possibility to obtain tools. The Biogas Caddy makes him independent and punctual.

Currently, the plant is in the commissioning phase. e-gas production will start this summer. From autumn 2013, the synthetic gas will be fed into the EWE NETZ GmbH grid. The potential of coupling electricity and gas will then be proven. Should excess capacities of wind energy or solar energy be passed on or stored as e-gas in large quantities in the future, the NEUMAN & ESSER compressors can also prove helpful because these are further applications where NEUMAN & ESSER is the technology driver.

Carefree Production Flow

Wehrhahn uses Pendulum Mills in Plants for Aerated Concrete

Aerated concrete, also described as gas concrete, is a high-quality, versatile construction material which is manufactured as stone, layout element or sheet and is used almost throughout the entire construction industry. Due to its low weight and comfortable processing options, aerated concrete is often the best choice when renovating or re-constructing older buildings, also for half-timbered houses.

The construction material is manufactured from unhydrated lime, water, cement and siliceous sand as well as a small quantity of aluminum. The mortar mix is poured in tubs where the metallic aluminum hydrogen gas develops. Several small gas bubbles are formed and foam up the material. The blocks are cut to the desired stone or construction component sizes using wires. By hardening it in the steam autoclaves, the aerated concrete is provided with its final properties.


Grinding Systems Avoid Bottlenecks

Due to these excellent properties, aerated concrete is establishing growing acceptance as a preferred material for buildings worldwide. Wehrhahn is the global market leader for production plants to manufacture aerated concrete. In addition to standardized systems, the company develops and manufactures individual system concepts which are formed taking special consideration of respective requirements and on-site conditions.

The production conditions for construction materials vary widely. Wehrhahn takes all relevant factors such as the production quantity, location, available space and much more into account. The challenge is to guarantee a perfect manufacturing process under the respective conditions, whilst taking the raw materials available into consideration. For example, unhydrated lime is a raw material which is not available in sufficient quantities in all regions. Wehrhahn therefore supplies production systems with lime kilns and grinding systems for own unhydrated lime production. This avoids bottlenecks.

More information about Wehrhahn

In the meantime, four NEA PM05 pendulum mills and one PM08 have been integrated into Wehrhahn’s production systems and support the trouble-free manufacturing of quality products. Heino Drewes, Project Engineer at Wehrhahn, says: “Our customers expect first-class technology “Made in Germany” from us and that is precisely what they have received from us for more than 120 years. The NEUMAN & ESSER mills fit perfectly into our concept. They are low-maintenance, stable, and supply the quantity desired with a narrow particle size distribution.” At the most, eight percent of the ground material exceeds the grain size of 90 μm. However, not only the NEA pendulum mills’ fineness convinces. NEA guarantees a minimum throughput of 4,000 kg/h for the PM05, for the larger PM08 even 9,000 kg/h. The exceptionally short stop periods for servicing and repairs are important for users.

»Our customers expect first-class technology "Made in Germany" from us and that is precisely what they have received from us for more than 120 years.«

Manufacturing an All-rounder

Unhydrated lime is manufactured on an industrial scale, whereby carbon dioxide is extracted from limestone at a temperature of more than 1,000°C, so-called lime burning. Burnt lime, caustic lime, calcareous earth and slack lime are further names used for unhydrated lime. With water, it reacts when heated strongly and becomes slaked lime. For Frank Verreck, NEUMAN & ESSER Mahl- und Sichtsysteme Area Sales Manager, unhydrated lime is an all-rounder: “After burnt lime is ground, it has a wide variety of industrial applications. Moreover, the better it is ground, the more precisely its properties can be fixed.”

Indeed, the area of application for the raw material is multifaceted: in the construction industry unhydrated lime serves as an admixture for mortar, plaster and paint, for the industrial manufacturing of lime sand bricks and for cement clinker. In the chemicals sector, the substance is used as a drying agent and for the absorption of carbon dioxide. The further areas of use for dehydrated lime include fertilizer lime, the desulfurization of crude iron and flue gas desulfurization. One important area of use is for manufacturing soda.

A clear view of Deep Oil

Petroleum Geo-Services uses the new BLUESAPS Technology

For their next two new builds the Norwegian company PGS will be using new BLUESAPS technology from NEUMAN & ESSER for seismic offshore searching. The oil-free compressor systems serve as a source of energy for the air guns on the seismic vessels. On the one hand, the non-lubricated NEA Seismic Air Power System saves a large quantity of oil. On the other hand, the oil-contaminated condensate developed by lubricated compressors no longer needs to be stored and disposed expensively.

The oil price, energy supplies and pipelines have had a significant influence on world politics for a long time now. The question of the energy supply today and in the future is a central factor in foreign policy, the economy and industry, environmental policy and traffic planning in most countries.

In 2011, global daily consumption rose to more than 90 million barrels for the first time and has remained more or less constant at this level. This is in excess of 14 billion liters per day to generate electricity, as the fuel for nearly all means of transport and transport equipment, for manufacturing plastics and several chemical products.

The exploitation of these huge quantities subjects the environment to dangers which must be minimized with all efforts, because at the latest since the oil platform Deepwater Horizon catastrophe in the Gulf of Mexico it is clear that the entire production chain from crude oil to the ready fuel must be carried-out with the highest degree of attention and foresight.

The production chain starts with locating crude oil reservoirs. For example, explosive charges were used for offshore searching up until the 1980s. Explosive devices generated the acoustic waves required to acquire seismic data and explore the sea floor. Stricter guidelines and regulations only reduce the burden for marine organisms due to seismic offshore activities as a result of the increased interest in protecting the oceans.

Today, the “seismic vessels”, as the search ships are called, virtually all use high-pressure air guns as pulse generators. A number of kilometer-long streamers filled with several hundred underwater microphones measure the reflected sound waves or blast waves and provide a detailed insight of the geological structure. The result of the seismic data acquisition can be depicted with a 2D or 3D image of the sea floor. The process is not only considerably safer for the staff, but also keeps the environmental damages lower. However, it ought not be denied that the use of seismic sources can be disturbing or damaging to marine organisms, under certain circumstances even lethal.

PSG Commitment

This is why Petroleum Geo Services (PGS) has written an environmental declaration. The Norwegian company offers a wide range of seismic services and products for the crude oil industry. These also include seismic studies and analyses, data recording and data processing.

In the declaration, PGS explains the environmental management across the Group according to the international Management Standard ISO 14001. The company, with its headquarters in Oslo and subsidiaries in more than 30 countries, is committed to the continuous improvement of the environmental compatibility of the seismic vessels. PGS measures, monitors and evaluates the worldwide applications in order to minimize the environmental risks and simultaneously to increase the efficiency of the exploratory activities.

Just by monitoring and observing the marine fauna, due to safety zones and restricted areas as well as appropriate time and weather windows, PGS has reduced the negative influence considerably. Above all, the so-called “Soft start” process has proven to be highly successful. The output of the air source is only increased gradually in order to provide the animals the opportunity to leave the sound source in good time.

The Norwegian company invests in new technologies such as the optimized fuel consumption of the seismic vessels for example. The revised design of the drive for the Ramform S Class has a higher effectiveness than the predecessor class, increasing its life time by 25% and its production capacity by 60%. The PGS Computer Center in London has received several awards for its low-energy concept. These include the “Environmental Project of the Year” and “Green IT Innovation of the Year” awards in 2009.

In the latest project, two new vessels of the most advanced RAMFORM TITAN series are equipped with NEUMAN & ESSER BLUESAPS systems, which are at present the cleanest solution for providing the Air Guns with compressed air.


The compressor manufacturer NEUMAN & ESSER (NEA) offers a comprehensive product range of high-pressure compressors as energy source for air gun systems. The NEA Seismic Air Power System (NEA SAPS) can either be equipped with electrical or diesel drives and can be installed both on and below the deck. The extremely compactly constructed systems are cooled by a closed cooling water system. Plate heat exchangers transfer the heat from the cooling water circuit into the sea water.

NEA SAPS combines a screw compressor with a reciprocating compressor. The screw compressor compresses the air from atmospheric pressure to approx. 15 bar; the reciprocating compressor compresses the air to the desired discharge pressure for seismic applications.

The NEA SAPS system range incorporates eight construction sizes as electrical version and six construction sizes with a diesel engine drive. The smallest system provides 20 m³/min (700 cfm); the highest capacity so far is around 78 m³/min (2,700 cfm). The higher the capacity, the shorter the possible intervals for shooting with the air guns. This provides more precise data by the systems and saves time.


Some 50 lubricated NEA SAPS systems serve as energy source for air guns on seismic vessels on all the world’s seven oceans. The new development BLUESAPS which is used for the Titan series by PGS is the oil-free variant of the Seismic Air Power System. The special feature of the NEA BLUESAPS units is that they provide clean air up to a pressure of 200 bar (3,000 psi) with a 2-stage oil-free screw compressor and a 3-stage oil-free reciprocating compressor.

The compressor is designed to avoid oil entering the compression chamber and therefore contaminating the compressed air. Per 1,000 operating hours, this variant saves up to 450 liters’ oil and 110m³ oil-contaminated condensate which would have to be stored and disposed expensively if lubricated compressors were used. Top manufacturing and production precision of the oil-free compressors ensure optimum efficiency.

Both the lubricated NEA SAPS systems and the BLUESAPS are water-cooled and equipped either with a water-cooled e-motor or a diesel engine. Without the oil trap for the lubricated screw compressor, the oil-free SAPS system is even smaller than the traditional variant.

One of the largest suppliers of seismic vessels had requested an oil-free version from NEUMAN & ESSER. The environmentally friendly version of the SAPS systems is absolutely well in line with the NEA BLUE concept which focuses on resource saving compressors. Not only these concrete enquiries but subsequent market analysis in the seismic area has shown a clear tendency for oil-free compressors. Thus, NEA developed the oil-free BLUESAPS concept, utilizing their many years of offshore and seismic experience. NEA has the new BLUESAPS in its program since summer 2011.

Sales & Product Manager Siegfried Meyer explains the advantages for the customer: “The awkward separation and storage of the oil-containing condensate is no longer required with BLUESAPS. In addition to the ecological aspect, the huge lubricating oil savings are a decisive argument from an economic view.” In order to avoid corrosion in the humid and saline environment, all parts of this oil-free compressor system which come into contact with air are made of stainless steel. In case of longer idle periods for the seismic vessels, for example during transportation, the oil-free BLUESAPS systems are purged with the nitrogen on board and conserved with closed valves, again with nitrogen.

Arno Thomas, NEUMAN & ESSER Sales Manager explains: “More than 80 years ago, NEA developed the first oil-free dry running compressors. They have become an indispensable component for breweries and for the food industry as well, but also for the chemical industry. I expect similar developments in the seismic sector.”

New investments

In 2011 Petroleum Geo-Services ordered two new generation Ramforms at Mitsubishi Heavy Industries Ltd. (MHI) one of the world’s largest shipbuilder that produces specialized commercial vessels. Delivery of vessel number one and two is scheduled for 2013.

Two additional vessels will be vessel number three and four in the Ramform Titan Class; planned delivery is 2015. Petroleum Geo-Services equips the two latest seismic vessels with a total of six BLUESAPS systems from the 62 series. These are then part of the eleven Ramform Fleet seismic vessels. The decision regarding the renewal and extension of the fleet comes at a time when the demand for seismic services is increasing.

After the market for seismic offshore survey regained momentum following a quiet phase since 2011, other suppliers also started to increase their investments in new equipment. The reason: according to the Seismic Offshore Report 2012, the demand for offshore survey is increasing rapidly, 10 – 20% in the past two years and in the coming year. The number of seismic vessels will only increase by 5% during the same period, as the study explains.

The increased demand results on the one hand from the higher deep sea oil requirements as the improved drilling technology can advance to greater depths. On the other hand, the more precise measurement devices also discover deeper located oil fields. This more efficient measurement technology is now used to re-explore fields. In this way, one of Norway’s largest fields was recently discovered in an area which was considered to already have been fully exploited.

The Ramform Titan Series has decisively developed success factors such as large spreads, long streamers and towing efficiency further. These factors make that little, decisive difference in geologically complex areas such as Brazil, West Africa, and the Gulf of Mexico. In areas which have been exploited as far as possible, such as the North Sea, the higher data precision reveals the new geological opportunities mentioned. Therefore, the Ramform Generation strengthens PGS’ market leader position with improved productivity and efficiency in seismic data acquisition.

The Service Team from NEAC Compressor Service

NEA ensures the permanent availability of the NEA SAPS systems, the compressed air sources for the air guns, with a specially trained team from NEAC Compressor Service. The service specialists have completed a challenging offshore training. Customers are provided with competent service for the compressor systems directly upon request, spare parts in accordance with a service agreement even within 24 hours.

Customers are also given specific individual training, either before or after commissioning and either on the vessel or at the packager’s. A further option is also possible: at the Training Center in Übach-Palenberg, Germany. The participants here gain deep theoretical and practical knowledge by implementing what they have learnt directly on the compressor block.

NEA is Socially Committed

NEUMAN & ESSER supports several charities and educational programs worldwide. Before the Christmas holidays, NEA USA and NEAC USA took the opportunity to partner with a local hunger relief charity, the houston foodbank, to hold a food drive to help families in dire need of food.

More about the Houston Food Bank


Hunger in US America exists for over 50 million people. That is 1 in 6 of the US population – including more than 1 of 5 children. The houston foodbank is the nation’s largest size Feeding America food bank and source of food for larger hunger relief charities in 18 southeast Texas counties. They have been named one of 10 Top-Notch Charities across the nation by Charity Navigator, as the houston foodbank reports. Powered by donors and with a network of 500 food pantries, soup kitchens, senior centers and other agencies, the houston foodbank is able to feed a total of 137,000 people each week and provides 50 million nutritious meals annually. NEA GROUP USA donated a total of 4,309 pounds of food. This equates to more than 70 pounds of food per employee and to 12,927 contributed meals. In addition to the food donation, NEA agreed to match $2.00 per pound to final donation weight. As a result, the US sister companies contributed an additional $8,618.00. According to the Houston foodbank, for every $1.00 donated they can fix three meals. Based on 4,309 pounds of food and the $ 8,618 match agreed to, this should provide nearly 40,000 meals.

INDUTEC Acquisition Extends Product Range

When NEUMAN & ESSER purchased the construction licenses for pendulum mills from the insolvent company Mehler more than 80 years ago, that was the starting signal for the construction and modernization of grinding and classifying systems of various construction types. In the meantime, the NEUMAN & ESSER GROUP has acquired the company INDUTEC from INDUTEC Industrietechnik GmbH’s assets in insolvency in order to ensure the future operation of the INDUTEC systems as OEM too.

Since March 1, 2013, the NEUMAN & ESSER GROUP is the new owner with the legal entitlement to manage the company and therefore the registered INDUTEC brand. With the acquisition, the NEUMAN & ESSER GROUP in particular owns the rights for the original drawings and patents for the INDUTEC products as well as the construction and order-related documents (e.g. manufacturing documents, machine history, and operating instructions).

Manfred Salgert, NEUMAN & ESSER GmbH Mahl- und Sichtsysteme Managing Director, values yet another aspect: “INDUTEC’s customer and supplier relationships are naturally interesting for us. The sales areas acquired from INDUTEC provide us with a more direct access to certain markets such as those in the Middle East or North Africa.”

However, also the technical know-how gained for the INDUTEC products is viewed as highly promising. In addition to the mills, these include in particular primary crushers and filters which NEUMAN & ESSER GmbH Mahl- und Sichtsysteme did not have in its product range to-date. These products are currently being examined in detail and tested for possible application.

Global Strategy for Tomorrow's Markets

Recognizing Technology Trends, Improving Purchasing and Sales

This year’s Global Purchase Meeting took place at the company’s headquarters in Übach-Palenberg on March 6 and 7 and the Global Sales Meeting on March 7 and 8. Franz-Josef Ritzen also reported on “Global Sales”, Rüdiger Schaaf and Mike Gorgas on “Future in CAD and Database”. Dr. Klaus Hoff presented new developments in compressor technology and Andreas Hahn the latest trends in revamp and modernization.

The topic of energy efficiency is being increasingly put to the fore. Therefore, the NEA GROUP puts forward various control systems for reciprocating compressors. These optimize the efficiency for new machines and can also be retrofitted to reciprocating compressors which are already installed such as BLUEStroke. Through the performance-adapted and virtually loss-free flow control in accordance with the actual requirements, only the actually required energy is used. Depending on the compressor size and workload, this can mean a considerable reduction in running costs for the operator.

Some workshops were held, too. One of these was “The Development of New Marketing Strategies”. Here, the cultural differences and product perception in the respective sales areas should be analyzed in order to design future marketing activities in a targeted manner. In the meantime, the buyers took an excursion to the company Boll & Kirch Filterbau GmbH, a worldwide NEA partner for the filtration of liquids and gases.

Safety Certificate for Field Representatives

The SCC is an international standard for safety, health and environmental management for providers of technical services. In order to obtain the unrestricted SCC(P) certificate for petrochemicals, both the normal evaluation criteria and specific requirements must be met.

In addition to their practical knowledge, employees also need a theoretical background. The SCC standard also requires that the operative managers must take a written examination of their work protection knowledge. There is a questionnaire for this and then the certificate is awarded. This examination is recorded on a database and entered in the employee’s safety pass. This examination must be repeated every ten years. Without this proof, some customers refuse admission to their premises, being the reason why all field representatives – engineers, mechanics and sales staff – are certified.

Stefanie Peters

40th Birthday

»Shush, shush, here she comes!«

“Shush, shush, here she comes!” was murmured through the dimmed canteen on Dec. 11, 2012. The entire workforce had gathered there early in the morning to surprise Stefanie Peters with a densely packed birthday program which was thematically tuned to her. To judge by her astounded facial expression, this was also more than successful. Thus she was welcomed first by the apprentice Janine Otten with her favorite song sung professionally, followed-up by amusing speeches by her father Klaus Peters and her brother Alexander who presented her a Santa-clad NEA Type 2S5/D company compressor dating from 1972, her year of birth, and – to the amusement of all – drew parallels between the compressor during its stubborn operation at NEA and his sister.

In a theatrical act, the “British Ladies” Martina Frenz and Inge Kaaf presented the joint birthday present from the family and the workforce: a “cleverly pre-planned” one week “UK to go” spring trip in a Jaguar E-Type.


Watch the Jaguar E-Type at “Deutsche Welle TV”

The colleagues from all locations around the globe had also packed their congratulations in the respective native languages in video clips and sent them. “The trip was a dream! “ as Stefanie Peters beamed when she returned in May this year. “The Cotswolds, Bath, the Derby in Ascot and the Morgan manufacture – we will never forget having had the privilege of experiencing these ports of call or other unforgettable moments in my favorite old-timer. All of this thanks to a committed group of people in Übach-Palenberg who already started working on the program “with a secret mission” back in September. Simply sensational!”

»Simply sensational!«

For all who have not been at the surprise party on December 11, 2012, gets a glimpse in the video below.

Healthy and More Relaxed

"Fit for Life" NEA GROUP Started the Second Health Day

The world is moving faster, more frantically and time appears to whizz by. Work piles up, both at work and at home. E-mails, appointments, the family: most of us are stressed. If the stress wins the upper hand and remains in the long-term, it can overstrain mind and body.

That is why NEUMAN & ESSER devoted itself to the topic of stress management for this year’s health days at the German locations Übach-Palenberg, Wurzen and Stassfurt. This time, prevention and information, for example, about donating organs and stem cells provided the focus of attention. The various topic areas and the multitude of stimuli were presented in lectures, courses and workshops during working hours.

The kick-off of the health days was always a healthy breakfast. All employees tried out the substantial variety of open whole-grain rolls and dark rye bread as well as yoghurt, muesli and fruit. Nutrition expert Jessica Dinter from the Institute for Corporate Health Promotion (BGF) showed the employees in Übach-Palenberg the hidden sugar and fat content innate in unhealthy food. The workforce’s great interest was noteworthy, not only in the healthy breakfast but in the overall Health Day. Stefanie Peters, Managing Partner, also emphasized this. She opened the Health Days with warm words: “We want you to feel well and healthy”.

During the further course of the Health Day, several participants used the opportunity to inform themselves in short lectures. For example, the German Bone Marrow Donor Center DKMS informed about stem cells and also as potential stem cell donors. They were provided the opportunity for this directly on-site.

More information about DKMS


Information booths from the health insurance companies AOK and BARMER, Addiction Help Center Aachen as well as AHG ASSIST Corporate Health Management were available to the employees the entire day and provided advice on general topics as well as personal questions.

AHG ASSIST Corporate Health Management

On the focus of stress management, Bettina Heinecke and Bernd Wittmann from AHG ASSIST presented informative lectures on “Coping with Stress – Every-Day Assistance”, thus arousing interest in this problem. Their lectures animated thoughts on personal early detection of stress-related health risks and possible dangers both within the vocational and private surroundings.

Since March this year, the medical and psychological advice of AHG ASSIST is provided to the NEA employees at all three German locations – 24/7. AHG ASSIST also handles problems within the social and family surroundings including legal questions. All information is treated strictly confidentially.

Yvonne Michel from the Addiction Help Center Aachen offered the NEUMAN & ESSER apprentices workshops for the problem of “Online addiction and new media”. The reports and experiences of a former Internet addict were particularly impressive. Stimulating questions and informative answers on computer addiction, Internet addiction or online addiction fascinated the apprentices.

The advent of the new media and the risks associated with them effect young people in particular. The extent to which the media have changed everyday life during the past years was not clear to several participants. Their imminent dangers and addiction potential to still fewer.

Relaxed, Healthy and Productive

The general check-up was a full-day program item. The preventive health examinations which were open to the entire workforce enjoyed a healthy response. Virtually all employees occupied themselves with various aspects of preventive health care. Blood pressure, sugar count and cholesterol were measured and urine tested. Even screening for the early detection of intestinal cancer was offered.

In Stassfurt, a local Lung Clinic participated, offering a lung volume test or so-called alveolar carbon monoxide measurement. This showed immediately who smokes and who manages without the unhealthy “ciggies”. The lung volume test will probably have given some of the smokers food for thought.

“The fact that the second Health Day was also received so favorably proves that our employees really confront themselves with the topics”, according to Stefanie Peters. “And naturally that we have selected the right topics.” “We had an exciting Health Day”, as Human Resources Manager Yvonne Vormstein confirmed. She was also delighted by the unanimous positive feedback. “I am certain that some of the employees will use the tips in order to handle stress in a more relaxed manner in the future.”

The NEA-nderthals invite

2nd NEA Soccer Tournament

Despite the seasonal break for the German Premier Soccer Division ‘Bundesliga’, the ball started rolling again on June 22, 2013 as of 10.00 a.m. The reason: as for the previous tournament four years ago, the GROUP company sports club the “NEA-nderthals” have invited to a 2nd soccer tournament at the VFR Übach-Palenberg stadium. Despite all sporting ambitions, the focus on fun and fairness is in the foreground. Unusual team names such as that of the previous winner Rapid Logismus (Company Robertz) or the Daimler Bä(h)ren (Company Mercedes Bähr) illustrate this intention. The STASSKOLER Dichtungsgeschwader and the Wurzener Kolbenfresser (NEA Wurzen) were there and measured their sporting prowess with the colleagues. Not only the hunger for goals, but also for cake and barbecue specialties was satisfied as physical well-being was catered for excellently. Everybody involved enjoyed exciting matches and the support of numerous fans and colleagues as the “12th player”.

The first six places of the tournament achieved:
1 The company Schlafhorst
2 Leo Robertz
4 NEA Wurzen
5 Daimler Bähr
6 NEA Übach-Palenberg Team 1

Big thanks to the organizers and the hardworking volunteers who planned and supported the soccer tournament.

NEA Supports Families

Child Care for Employees’ Children

The family patterns have been on the move for several years. Different family situations arise, professional circumstances change. Women not only wish to enjoy the same rights in their working life, but also actively use opportunities. Therefore, more and more parents have the desire to reconcile family and career. NEUMAN & ESSER wishes to support the employees and their families effective here. For some time now, NEA has made efforts to provide child care for employees’ children under three years old. Thanks to a cooperation agreement with the non-profit organization pro multis this has now succeeded at the Übach-Palenberg site. pro multis supports five daycare centers for children close to the headquarters. Three NEA children already make use of the offer, a fourth will follow suit soon.

Elivia Sinem Peters

Hello, I am new here …

Allow me to introduce myself. My name is Elivia Sinem Peters and I am the youngest offspring in the Peters family. Take it from me: most things start small and some large. Here the smallest is the largest! Even if not measured in centimeters as I was only 51 cm tall, and that with a weight of 3160 grams when I saw the light of day on September 28, 2012. Since then, I have already worked hard and have grown. My profile: a lively girl with considerable powers of self-assertion and, as far as I can judge from my view, my family is extremely happy to be backed-up by me! I have attached my job application photo.

New Staff Facilities

“For Hygienic Freshness and Powerful Cleanliness”

As a former advertising slogan phrased it. This is more than true for the last substantial investment for the time-being in the company building at its Übach-Palenberg location because reconstruction work for the staff facilities at the headquarters could be concluded in October 2012. In total, 138 new lockers and ten new showers and toilets were constructed for the workforce. The Peters family handed over the symbolic key to the workers’ councils on Oct. 17, 2012. Following renovation of the canteen in 2011, a further step was taken to considerably improve the employees’ surroundings. With the staff facilities, a miniature “wellness temple” entered everyday working life. Everything shines and gleams.
