About en2Aix
en2Aix – energy engineering Aachen GmbH was founded in August 2006 by Dr. Bernd Hillemacher and Univ.-Prof. Dr. Reinhold Kneer as a spin-off of the Chair of Heat and Mass Transfer (WSA) at RWTH Aachen University. The company offers engineering and testing services for complex tasks in energy and process engineering. The spectrum ranges from fundamental experimental model investigations to analytical and theoretical/numerical CFD calculations, through to application-oriented evaluation and optimization of thermal and process engineering applications. Further service areas include building simulation for the energy optimization of buildings as well as pyrometry, i.e. non-contact, largely surface-independent and fast temperature measurement; here en2Aix supplies both its own hardware (e.g. the en2Aix Fire III pyrometer) and services for a wide range of use cases. Customers are companies and public institutions from energy and process engineering as well as mechanical engineering, including, among others, Bosch, Siemens, ThyssenKrupp, RWE, Volkswagen, MAHLE, Lufthansa, GEA, FEV and RWTH Aachen. The company is headquartered in Würselen near Aachen, with direct access to current science technologies through its close ties to RWTH Aachen University.
