Digital Engineering

  • for Thermal, Process and Energy Systems

Simulation. Complex Dynamic Systems.

We simulate thermal systems and energy systems with physically based models. Thereby, we can investigate different concepts in early stages of development or comprehend and improve existing systems with all its interactions.

Control. From Concept to Implementation.

For reliable and efficient operation of thermal systems a multiplicity of feedback control problems must be considered. We support you in the development and implementation of the best control concept for your system. We take appropriate measures to meet your specific requirements: from classic PID controllers to model-based methods.

Optimization. Maximum Efficiency, Minimal Costs.

Almost every engineering task can be described as a mathematical optimization problem. We support you in describing and solving the optimization problem. In combination with your knowledge and experience, you gain valuable tools to improve your systems to the best costs and conditions.

Our intern Joy has drawn up a CO2 balance for us for the year 2018. In her calculations, she comes up with 0.93 tons CO2/person for all three scopes. To account for uncertainties in our balance we compensated twice the amount at atmosfair. But how can we get even better and avoid emissions instead of compensating them? The only thing we came up with, is to switch to green gas for heating. But especially for scope 3, we don't see much room for improvement. Do you have any ideas or remarks? Just drop us a line.



Still, emobility suffers from a strong reduction in range on cold winter days. TLK Energy is researching latent heat storage concepts for BEV in collaboration with e.GO Mobile, DLR and Access to ensure that the heating of the vehicle is no longer at the expense of the battery. In the LatHe.GO research project, we are responsible for modeling the vehicle cabin and integrating the storage system. If you like to learn more about the project and want to know what you can achieve with system simulation, just contact us.
This project is funded by the European Regional Development Fund (ERDF).
