At the German sites in Übach-Palenberg, Mülheim an der Ruhr, Staßfurt and Wurzen state-of-the-art production machines are extremely flexible in response to changing customer requirements. The machine inventory allow to comply with manufacturing tolerances in the range of a few hundredths of a millimeter of compressors up to 100 t. NEUMAN & ESSER has also adapted the testing technology to the growing quality demands of its customers. On the crack test units, fluorescent test particles detect even the smallest defects on the surface of the component. By means of 3D coordinate measuring devices, the production companies are able to measure critical components with extremely tight tolerances in shape and position. Measuring accuracy is within a range which is smaller by the factor 10 than the diameter of a human hair.
Numerous simulations during the design ensure the long life time of the compressor and grinding systems. These include among others the finite element method as well as static and dynamic analysis such as flexural vibrations or torsional stresses. For many years, the NEA GROUP has also been using the self-developed KO3 lay-out software, which even allows to optimise sleeve bearing lubrication.
NEUMAN & ESSER GmbH & Co. KG is the production site at the NEA headquarters in Übach-Palenberg. It is the heart of the NEA GROUP. Here, NEUMAN & ESSER manufactures high-performance machines “made in Germany” such as reciprocating compressors, mills, classifiers and spare parts. The “Maschinenfabrik” supplies all NEA GROUP locations worldwide. With currently more than 230 highly trained, specialized personnel, this company employs more staff than any other company of the GROUP. Under the roof of the machine factory are the central staff offices R&D, IT, HR, Finance and Marketing for the entire company group.
As a large, certified service company, NEAC Compressor Service has supported its customers with installation, commissioning, maintenance and repair services as well as with the supply of spare parts for all types of process gas and industrial gas compressors for 30 years. In addition to these standard services, NEAC offers special support in the fields of modernization, machine monitoring and troubleshooting. Based on the OEM licenses, the more than 70 service technicians provide both spare parts and first-class service for several former reciprocating compressor product lines.
If required, a competent engineering team establishes a good value solution between repairs and spare parts at short notice. They work out solutions to minimize downtimes and repair costs within the scope of technical discussions. With the tailor-made service agreements, NEAC guarantees high availability of the system to be supported. Thanks to their global network of specialists and support from the NEA GROUP R&D area, NEAC can access piston compressor know-how that always tallies with the current state-of-the-art.
NEUMAN & ESSER Deutschland was outsourced from NEA Maschinenfabrik at the end of 1998. Since then, the team of 60 employees deals with the areas of plant engineering, project engineering and the sales of NEA compressor systems as well as the revamping and modernization of own and third-party compressors and compressor systems. NEA Deutschland supports customers in the countries of North, West and Central Europe, the CIS States, in Africa as well as in Israel and Japan. The procurement and assembly of the entire periphery for the compressors “Made in Germany” is processed by the company in accordance with the local technical regulations. The systems are primarily used in the gas and oil, oxygen and hydrogen compression, chemical processing, petrochemicals and energy areas.
With the customers’ and their markets’ individual requirements, NEA Process Technology has developed from a mill manufacturer to a solution provider, including upstream and downstream system components. To-date, more than 1,000 NEA milling and classifying systems are in use worldwide. On the one hand, they are used in the traditional ceramics, pigment, preparation and fertilizer industries, but also for manufacturing sweets, for chemicals and powder coating production. In addition to its 50 employees at the Übach-Palenberg location, NEA has founded independent companies in Brazil and the USA for sales and plant engineering and sales offices in Egypt and China.
NEA carries out experiments with the customer’s material at its generously dimensioned Test Center; After Sales Service and individual solutions for the modernization and revamp of existing grinding systems round off the performance range.

Alongside the independent NEA companies STASSKOL and HOFER and the Übach-Palenberg headquarters, the machine factory in Wurzen is the fourth production location in the GROUP. The NEA Wurzen location, close to Leipzig, has some 130 employees. Here, NEUMAN & ESSER produces the compressors for the lower output range up to 2,700 kW actuating power. In addition to API 618 compressors, reciprocating compressors are also manufactured at Maschinenfabrik Wurzen in accordance with the NEA standard. One special area of expertise is the demanding oxygen compression as well as the construction of acetylene compressors. Founded as “Schütz & Hertel” in 1879, the company looks back on a history of some 140 years. The successful company has been an important pillar of the NEUMAN & ESSER GROUP since 1991.
