thermotec

What thermotec does

thermotec engineering services GmbH is a privately held German engineering services firm headquartered in Garching near Munich (with an operational office in Oberschleißheim) that provides specialized simulation, calculation, and experimental testing services for thermal and thermofluidynamic processes. The company serves technology-leading customers primarily in the German automotive industry and, to a lesser extent, aerospace, defense, industrial and chemical sectors, addressing development questions around cooling systems, oil circuits, thermal engine models, vehicle-level heat management, CO2 reduction and fuel-consumption optimization.

Its service portfolio is structured around 1D thermohydraulic network simulation (using GT-SUITE, Flowmaster, LMS AMESim, Dymola, MATLAB/Simulink) and 3D CFD simulation (using STAR-CCM+, COMSOL, RadTherm, OpenFOAM), supported by mesh generation (ANSA), measurement data processing (NI DIAdem, TurboLab, Agilent VEE Pro) and internally developed automated pre- and post-processing for evaluating many design variants. Concept development, feasibility studies and physical testing complement the simulation work, allowing customers to validate product functionality before prototyping. The firm maintains ISO 9001:2015 and ISO 27001:2017 certifications and a cooperation with the TU München Chair of Thermodynamics.

thermotec generates revenue through project-based professional services, with pricing tailored per engagement and not publicly disclosed. It goes to market via direct sales engagement with the development departments of enterprise customers (Audi, BMW Group, Mercedes AMG, Porsche, Continental, ZF, Bosch, MAN, Behr, Faurecia, Renault, EADS, MTU Aero Engines, Rohde & Schwarz, Siemens, Linde, Hilti, Evonik Degussa, KraussMaffei, Gore), operates regionally within Germany, and is led by two Managing Directors (Dipl.-Ing. Fabian Hoseit and Dr.-Ing. Robert Tauscher). The firm is small (1–10 employees), bootstrapped, and has no disclosed external investors, parent company, or M&A activity.

Broad incumbents

• COMSOL Inc. Provider of the COMSOL multiphysics simulation platform used by thermotec. As a software-led incumbent with an adjacent consulting/services network, it is a comparable player in the thermal/fluid simulation market.
• Altair Engineering: Simulation software and services provider spanning structural, thermal and fluid dynamics. Altair offers engineering services alongside its software, competing for the same type of thermal-management simulation engagements.
• Ansys Inc. Global simulation software leader (Fluent, Maxwell, etc.) used across thermal, fluid and structural analyses. While not a direct services competitor, Ansys shapes the tooling ecosystem thermotec operates within and competes at the high-end simulation services tier.
• ESI Group: Simulation software and services firm focused on manufacturing, materials and virtual prototyping, with overlap in fluid/thermal simulation for automotive and industrial customers. Broad incumbent alternative to specialist engineering services providers.
• Siemens Digital Industries Software (Simcenter): Simcenter portfolio (including STAR-CCM+, which thermotec uses) covers 3D CFD, thermal and systems simulation, with adjacent services. As a broad incumbent it competes for the same thermal/fluid simulation budget that thermotec addresses, especially at Siemens' own industrial customers.
