Arcanum Energy Systems GmbH & Co KG


Renewable energies, gases from renewable sources, comprehensive services in gas processing plants and process engineering

The transaction
Arcanum Energy Systems GmbH & Co KG (Arcanum), based in the town of Unna near Dortmund, became part of the NEUMAN & ESSER GROUP (NEA) on 30 April 2020. The company was transferred by way of a share deal. The merger will enable both SMEs to combine their services and in future provide solutions covering the entire process chain, from biogas plant and biogas treatment to grid feed-in, including further processing into green hydrogen.

The company
As a leading service provider and consulting firm, Arcanum provides energy supply companies, agricultural operators and municipalities with customised strategies and business models in the field of renewable energy. Its portfolio includes identifying locations and technical advice along with the approval, implementation and commissioning of end-to-end biogas systems, particularly biogas treatment and grid feed-in systems throughout the value chain. The company also manages what are termed “biogas pools”, in which a number of municipal utilities and biogas plants come together for the purpose of utilising biomethane in an eco-friendly way in combined heat and power plants for electricity and heat generation.

The buyer
The NEUMAN & ESSER GROUP (NEA), based in Übach-Palenberg near Aachen, is a leading manufacturer of piston and diaphragm compressors, compressor systems for air and all technical gases, and a provider of a wide range of services. The family-owned company’s strategic business units are Compressors, Services, Process, Sealings and Digitals and currently employs more than 1,100 people at four production sites across Germany as well as 22 engineering and service companies in ten other countries. By acquiring Arcanum Energy, the group intended to strengthen its competence in the field of “green gas”. With Arcanum, the NEA GROUP will in future position itself as a solution provider for the entire process chain, from biogas plant and biogas treatment to grid feed-in, including further processing into green hydrogen.

The role of benten capital

As part of this process involved the immediate market environment, the utmost confidentiality and diligence were required. In the course of the project, intensive negotiations in parallel to the M&A process succeeded in “developing” several interested parties at an international level. Thanks to the many shared strategic opportunities available, including the further development of market trends such as power-to-gas and bio-LNG, the seller – who will continue to manage Arcanum’s business activities – opted for the merger with NEA. Within benten capital, Dr Florian Eisele and Frank Galgenmüller were responsible for overseeing the transaction process.
