TLK Energy product offering
Product offeringCore offering
TLK Energy develops and licenses Modelica-based simulation libraries (TIL Suite, TIL Adsorption, Process Systems Library) and a cloud simulation platform (sim.TLK) for thermal, refrigeration, HVAC, and process engineering applications. The company also delivers project-based engineering, modeling, hardware-in-the-loop testing, and energy optimization consulting to industrial manufacturers, alongside Modelica training courses and the ThermoSim conference.
Product overview
TLK Energy offers a platform-plus-modules architecture centered on the TIL Suite, a Modelica-based simulation library for thermal and process engineering. The core TIL Suite provides foundational modeling capabilities, supplemented by specialized modules including TIL Adsorption for adsorption processes and the Process Systems Library for additional process components. The company also provides sim.TLK, a cloud-based simulation platform that delivers these simulation capabilities via web access. All products are built on the object-oriented Modelica modeling language and leverage the TIL Suite-Bibliothek library models.

Products and services
- TIL Suite Comprehensive Modelica-based simulation library for thermal and process engineering applications, providing models and tools for simulating thermal systems across various engineering domains. Targeted at R&D engineers in industrial manufacturing, HVAC, automotive, and process engineering.
- TIL Adsorption Specialized Modelica library for adsorption processes and thermal energy storage, supporting applications such as Direct Air Capture and dry rooms. Sold as an add-on module to the TIL Suite for engineers working on adsorption-based thermal systems.
- Process Systems Library Modelica-based library developed in collaboration with LTX Simulation under the SBC.sim joint venture, providing specialized process system components (compressors, expanders, process control) for simulation models. Used by engineers requiring hardware-in-the-loop and process-engineering simulation.
- sim.TLK Cloud-based simulation platform that delivers TIL Suite models and simulation capabilities through a web interface, built on Modelica and Weiss Technik simulation models. Enables engineering, sales, and marketing teams to access thermal simulation without local installation.
- Engineering and Simulation Services Project-based modeling, simulation studies, and consulting services for digital design and optimization of complex thermal, refrigeration, HVAC, and process engineering systems. Delivered to industrial manufacturers on a quote-based engagement.
- Energy Consulting (EnEfG / BAFA Module 5) Industrial energy efficiency consulting services including Energieberatung (energy advisory), EnEfG (German Energy Efficiency Act) compliance consulting, and BAFA Module 5 Transformationsplan support. Targeted at industrial clients needing regulatory compliance and funding program documentation.
- Modelica Training Courses Instructor-led Modelica training courses and workshops covering physical modeling fundamentals and advanced thermal system simulation using the TIL Suite. Delivered to engineers and technical staff at customer sites or company facilities, with a compact Pinch Analysis course also offered.
- ThermoSim Conference Annual Fachkonferenz (expert conference) on thermal system simulation focusing on Modelica and FMI standards. Generates revenue through registration fees (standard 695 EUR net; early bird 495 EUR net through June 2026), sponsorship, and exhibition. Includes presentations, networking, and serves as a thought-leadership platform.
- Hardware-in-the-Loop Testing Services Real-time hardware-in-the-loop testing service for validating thermal components and control systems with physical hardware under simulated operating conditions. Developed in collaboration with Forschungszentrum Jülich and NEUMAN & ESSER under the HyControl project, funded by the Ministry of Economic Affairs of North Rhine-Westphalia and the EU with 1.96 million euros.
