"Compression" is a good word to describe everything that Aerzen does. It describes our core business: compressing gases. And it characterizes our path as a company: concentrating on our customers' applications and the demands that come with them so that we can help increase the performance of their processes. 150 years of company history have gone into our new guiding principle: "Expect Performance". In other words, you can expect only the best for your processes -- and "Made in Germany" as well!Innovation, customer contact, focus on service: typical virtues of a mid-sized company.Aerzen began life in 1864 as Aerzener Maschinenfabrik. In 1868 we built Europe's first rotary lobe blower. The first turbo compressors followed in 1911, and the first screw compressor in 1943. We have always succeeded in reinterpreting our machines' basic technology to make them even more efficient and capable of handling the hundreds of applications that our customers bring to us. With our structure a mid-sized company -- and we place great value on this, even in the era of globalization -- we are motivated to become increasingly innovative, to concentrate fully on our customers' processes. Focus as a form of compression.Aerzen machines transport, compress, and measure gases. There is practically no industry that can afford to be without machines like these. Our portfolio of rotary lobe blowers, rotary lobe compressors, rotary piston gas metres, screw compressors, and turbos covers almost all of today's industrial applications -- for intake volume flows from 1 to 120,000 m3/h. Behind this are 150 years of process work and industry experience. Aerzen machines, running continuously under difficult conditions, do their job precisely, efficiently, and reliably -- year after year, decade for decade.

Aerzen, one of the internationally leading manufacturers for blowers and compressors, successfully sold its product division rotary piston gas meters to RMA Rheinau GmbH at the end of the year 2018. As part of its growth strategy and future orientation, the traditional Lower Saxony-based company will concentrate more on its core products and markets.The AERZEN rotary piston gas meter has been a product rich in tradition at Aerzen since 1930. Due to their design, however, demand and sales of measuring instruments were concentrated primarily on the German market. On the basis of the international growth strategy, which mainly focuses on compressor technology and application specialization, the AERZEN gas meter no longer fits in with the future target orientation. Against this background, the management decided to give up the product division and sell it to a successor with industry know-how."For AERZEN it was very important to find a buyer who would offer the product range to our partly long-standing customers in the usual quality", says the CEO, Klaus-Hasso Heller. "We are very pleased that we have now found a reliable partner in RMA, based in Rheinau, who will not only continue the AERZEN technology, but will also develop it further in this way", Heller continues.The transfer of the gas meter product division took place successfully on 31.12.2018. For new inquiries AERZEN kindly asks for direct contact with the company RMA.About Aerzen USAAerzen USA is a wholly-owned division of the German manufacturer, Aerzener Maschinenfabrik GmbH, and has been a recognized world leader in the production of rotary positive displacement machines since 1868.

The successful screw compressor generation Delta Screw from AERZEN gets an addition: With the VM 100 compressor package, the versatile E-Compressor series now comprises seven model variants. Its distinguishing features: the efficient technology for use in the upper volume flow range and the integrated electric acoustic hood fan.The new development of Aerzen will be presented for the first time at COMVAC 2019, the leading international trade fair for compressed air and vacuum technology in Hanover. The new compressor type is designed for a volume flow range from 1500 to 7620 m3/h and covers a maximum differential pressure of 3.5 bar. The application specialist AERZEN is thus responding to specific practical requirements in the low-pressure range and the constantly growing demands for high-performance and efficient technology. All in all, the broad product range of E compressors includes 7 sizes in the volume flow range from 330 to 7,620 m³/h and drive capacities from 30 to 630 kW.A special feature of the new model type is the already integrated acoustic hood fan. Another new feature is the space-saving horizontal position of the discharge silencer. Like all E-Compressors of the series, the VM 100 has an acoustic hood with internal supply and exhaust air louvers, which favors the compact design. Flow-optimized intake channels minimize pressure loss significantly. A significant improvement in performance can be achieved by supplying cool outside air directly into the intake filter. Unique is the absolutely oil- and absorbent free compressed air technology of AERZEN. Oil-free operation is certified according to ISO 8573-1/Class 0. The patented principle of the built-in reflection silencer protects against contamination and ensures process reliability over the entire service life of the system. And the latest addition to the E-Class also impresses with its flexibility. Various equipment options and a comprehensive range of accessories complete the VM 100's operational capability.Efficiency and performance of the Delta Screw E-Compressors are safely controlled by the AERtronic software. The integrated panel reliably and conveniently monitors the intake, discharge and oil pressure as well as the discharge and oil temperature.According to the manufacturer, all Class E screw compressors score points with a strong energy balance. The technology leader from Aerzen calls the sophisticated concept of performance optimization and resource utilization, profitability and flexibility "efficiency plus". With a saving of up to 6 % in energy costs over an operating period of 10 years, the investment volume is almost covered.The specialization in application-oriented customer solutions testifies to the competence and experience of the renowned mechanical engineering company. Special solutions, also ATEX-compliant, prove the excellent references from various industries and fields of application. Even under difficult environmental conditions or with special gases, the best possible results can be achieved.Therefore, Aerzenis of the opinion that individual consultations should already be conducted at the beginning of the planning phase. With the invitation "Let's talk" the company would like to invite to an expert dialogue and reduce inhibitions. At the COMVAC stand, planners, decision-makers, buyers and operators will have the opportunity to do so.About Aerzen USAAerzen USA is a wholly-owned division of the German manufacturer, Aerzener Maschinenfabrik GmbH, and has been a recognized world leader in the production of rotary positive displacement machines since 1868.

From the start of 2017, for driving the AERZEN vacuum blowers a new drive motor is used. In future, only one motor design (HM) will be available for neutral and aggressive gases. This synergy effect reduces the variant diversity of vacuum blowers to only one motor drive with hermetically sealed drive.The AERZEN vacuum blowers (previously called canned motor blowers) suitable for permanent operation and with hermetic drive make particularly short pumping times possible and are used in industrial high vacuum technology for a vacuum range of 200 bis 10-5 mbar together with one or two backing pumps. These blowers work with a fully hermetic drive. The drive shaft is sealed by an integrated motor without connecting passage to atmosphere. Due to the almost doubling of the speed for smaller sizes, very short pumping cycles result compared with vacuum blowers with a speed of 50 Hz, which leads to a considerable acceleration of the production processes for the operator. Even if, for increasing the performance further, two backing pumps and one vacuum blower are integrated into a pumping set, the entire unit still distinguishes itself by a particular compact design - a special advantage concerning multi-systems with numerous pumping sets.Vacuum blowers made by AERZEN are available in type of construction HM for neutral gases in 9 sizes for theoretical nominal intake volume flows from 406 to 15,570 m³/h. These systems are used for the generation of industrial vacuum, for example in chemical and process engineering, in foil and glass coating, evacuation of hydrogen, in helium leak detection systems. In addition, these blowers are working in the semiconductor industry, in microelectronics, in the manufacture of flat screens, in laser technology and in solar technology. The blowers can convey in both directions - vertical and horizontal. Due to the standard water cooling they are appropriate for application under clean room conditions. An excellent mechanical resistance (up to 150 mbar) reduces the pumping times. Moreover, the application of a frequency converter makes a high control range (1:5) possible, and therefore, the use of smaller blower sizes. Thanks to different motor variants for cyclical and continuous operations, an individual solution can always be found, even for special applications.The CompanyIndustrial plants all over the world are provided with gaseous media using AERZEN blowers and compressors. The innovative AERZEN machine technology represents experience of more than 150 years company history. The range of products includes rotary lobe compressors, positive displacement blowers, turbo blowers, screw compressors and gas meters. AERZEN blowers, compressors and gas meters are tested and certified according to DIN EN ISO 9001. There is a variety of product offerings from standard products to customised solutions.In addition, the AERZEN After Sales Service offers the complete range of services - from the full maintenance contract to repairs and upgrade of existing plants.

AERZEN set standards with the Delta Blower positive displacement blowers and raised the bar ever higher for performance, economic efficiency and environmental protection. To expand upon the success of the blower series, an exciting new design sets energy saving records. The innovative assembly concept combines proven features and newly-gained advantages. Delta Blower G5plus achieves up to 5% more energy efficiency and offers more flexibility to meet even special requirements.AERZEN Delta Blowers Generation 5 are positive displacement blowers for almost any application and have already convinced many users by their robustness and long-life cycle. Especially, their performance data are impressive. They reach intake volume flows of 30 to 15,000 m3/h at a control range of 25 to 100 % and overpressures of up to 1,000 mbar. The Delta Blowers convince in many industries, for example during water and wastewater treatment, aeration, filter backwash, pneumatic conveyance, gas conveyance, degassing or dedusting.AERZEN has developed the successful concept with the new Delta Blower G5plus and raised it to the next technological level. Apart from the known advantages of the series, it is the new compact design that attracts attention. It allows a space saving side-by-side installation and requires less space in the machine room. All blowers achieve oil-free operation class 0 as per ISO 8573-1 according to the AERZEN Environmental Concept. They are free of absorption material up to 100 % and require oil change only after 16,000 operating hours. Energy-efficient motors class IE3 are used as standard and suction is still at the cold side of the assembly.What is absolutely new with the Delta Blower G5plus is up to five per cent energy saving by means of an optimised intake filter silencer with lowest flow losses, high-efficient electrically driven fans and an optimised standard base support which makes reduced pressure losses possible. The warm exhaust air is routed over the roof of the acoustic hood to connect a separate channel for optional heat recovery. But the “plus” also refers to the additional comfort of Delta Blower G5plus: The new acoustic hood concept reduces the installation surface area by up to 10 % depending on the size and the acoustic hood door makes easier and faster access possible to facilitate the maintenance of the assembly. The multifunctional, extended base support creates a plus of flexibility by an integrated spark arrester (ATEX), the preparation for installation of a start unloading device, components for installation of third-party motors and a patented reactive silencer.AERZEN supplies the technically optimised and conceptionally enhanced Delta Blower G5plus positive displacement blower in four sizes for volume flows of 440 m³/h up to maximum 3,600 m3/h.

The ASME PTC-13 test code outlines the process used to determine the “wire-to-air” performance of packaged blower systems.

Stating the fact that the economical operation of a wastewater treatment plant depends largely on the design and interplay of the aeration and process controls, this paper takes a pragmatic approach and presents information that will help the engineer to appropriately define both the design and the evaluation criteria of various blower technologies suited for wastewater aeration. Four types of blowers are examined; two dynamic and two positive displacement machines, including a comparison made specifically based on the treatment of wastewater. The paper details how energy usage minimization can be achieved by adopting the approach of right-sizing, defining the operating range and matching the blower technology to the application, and comparing operating data over time.

Illustrating how Aerzen USA has achieved 17 per cent annual growth since 2011 in order intake and headcount by 75 per cent over the same period, this paper presents the company's ongoing process improvement plan, wherein the organization initiated a culture that put employee development at the top of the agenda. It highlights Aerzen USA's new facility powered by a solar array of almost 700 panels, that was named one of the Best Places to Work in Pennsylvania in 2013 and 2015. Having invested heavily in lean training and leadership development, it states that the challenges of growth and success was met by focusing on giving Aerzen employees the education, training, skills and tools they needed to manage their work toward common goals. Covering the Team Leadership and train-the-trainer program, it presents the costs to the company for this initiative as 2 per cent of the payroll, and concludes that the way forward to meet all challenges in the company is by developing people.

For civil, environmental, and mechanical engineers in the wastewater treatment industry, turbo was a sea change from Positive Displacement and centrifugal machines driven by NEMA motors. This paper highlights how purchases were made from fledging manufacturers initially in the belief that this new technology would be energy efficient, and easy to use. It reveals that the failure of some turbos produced by these manufacturers were so spectacular that they attracted negative feedback ranging from people not wanting any part of this technology, to those who believed that airfoil bearings were less robust than magnetic bearings. It concludes that there is nothing to fear from the turbo and that Aerzen would like to clear the misconceptions about this technology, present the advantages and challenges faced, include the lessons learned by Aerzen from their earlier installations, and offer practical guidelines for successful implementation of the technology.
