The Gesellschaft für thermodynamische Prozesse, Entwicklung und Consulting mbH (GetPEC) was established in 2016 as a spin-off from the Institute of Technical Thermodynamics (TTD) of the Technical University of Darmstadt. We offer tailor-made solutions for your technical questions as well as advice in all thermodynamic areas. You can benefit from the many years of experience of our employees in both analytical-numerical and experimental areas. We provide you with a perfect interface between the scientific understanding necessary for research and development tasks and the economic and customer-specific requirements.


Martin Freystein Executive Partner

Martin Freystein is the managing director. As a research assistant at TU Darmstadt, he investigated the atomization behavior of complex fluids on rotary atomizers and also led several research series on fluid boiling in weightlessness as part of parabolic flights by the European space agency ESA. Through his subsequent work in the energy industry, he specializes in the coherent consideration of technical, economic and legal questions in the entire energy technology area.

Axel Sielaff Founder

Axel Sielaff is a technical expert and founder of GetPEC. He did his doctorate at TU Darmstadt with a focus on two-phase heat transfer. At the TTD, he assumed responsibility for the experimental methods and measuring techniques as well as the group leader boiling and vaporization. He is a proven specialist in all questions of heat transfer as well as experimental investigations and plant optimization. The design and construction of experimental components for the International Space Station (ISS) is just one example.

Felix Brinckmann Senior engineer

Felix Brinckmann did his PhD at TU Darmstadt with an experimental and numerical work in the field of drying processes. The calculation methods he developed were then transferred to the commercial simulation software ANSYS. Due to his subsequent employment with a medium-sized automotive supplier and a market-leading medical technology company, he is our specialist for all questions regarding product safety, quality assurance as well as standards and guidelines.

Peter Stephan Advisory partner

Peter Stephan has headed the Institute for Technical Thermodynamics at TU Darmstadt since 1997. He is co-founder of the Cluster of Excellence "Smart Interfaces" and spokesman for the profile area "Thermo-Fluids & Interfaces" and the Collaborative Research Center "1194 - Mutual Influence of Transport and Wetting Processes" . He has published over 250 articles in specialist journals and at conferences , is chairman of the editorial board of the VDI Wärmeatlas and the ProcessNet specialist group on heat and mass transfer, and is a board member of several international journals. Peter Stephan is a consultant in all scientific questions.
