Modelon is excited to announce that [TLK Energy GmbH](https://tlk-energy.de/en) has joined as an official reseller of Modelon Impact. This partnership also brings expanded compatibility and support for [TIL Suite](https://tlk-energy.de/en/software/til-suite) and the [Process Simulation Library (PSL)](https://tlk-energy.de/en/software/process-systems-library), enhancing dynamic simulation capabilities for thermodynamic systems.

TLK Energy GmbH, a leading consultancy specializing in thermodynamics and energy systems, has expanded its collaboration with Modelon to offer broader compatibility and access to its Modelica-based libraries through Modelon Impact, Modelon’s cloud-native system simulation platform.

TIL Suite (developed and owned by TLK-Thermo) enables detailed modeling of thermodynamic systems, including heat pumps, battery cooling, and air-conditioning. The Process System Library (PSL) supports the design and optimization of advanced Power-to-X processes. Now fully compatible with Modelon Impact, both libraries can be used alongside Modelon’s extensive library suite, empowering engineers to model, simulate, and collaborate in a cloud-native environment without local installations or manual maintenance.

This partnership addresses a long-standing challenge in system simulation: the need to source and integrate specialized libraries from multiple vendors using disparate tools. By bringing TIL Suite and PSL to Modelon Impact, teams now gain seamless access to powerful libraries within a modern, cloud-based environment, saving significant time and IT resources. Additionally, with Modelon Impact’s post-processing capabilities and connectivity to custom web applications, engineers will be able to get more out of their simulations.

As part of this expanded partnership, TLK Energy GmbH is now an official global reseller of Modelon Impact and will offer training courses using the platform. Engineers can not only access the tools they need more easily but also upskill faster, ensuring they get the most out of their simulation investments.

“Our partnership with TLK Energy GmbH is a meaningful step forward for the Modelica community. By combining TLK Energy’s deep domain expertise and trusted libraries with the flexibility and accessibility of Modelon Impact, we’re removing long-standing barriers to simulation. Together, we’re empowering engineers with a seamless, open-standard experience that accelerates innovation across thermodynamic applications.”
 — Gustav Nyrenstedt, Product Manager, Modelon

“Our cooperation with Modelon allows us to further enhance the user experience of our libraries by leveraging Modelon Impact’s cloud-based technology and intuitive user interface. This partnership brings the original vision of Modelica to life—giving customers the freedom to choose between professional simulation tools based on their specific needs and preferences.”
 — Manuel Gräber, CEO, TLK Energy GmbH

The collaboration aligns with Modelon’s strategy to build the largest ecosystem of Modelica-based libraries compatible with a commercial system simulation tool, empowering users to fully leverage the breadth and power of Modelica modeling and simulation.
