DOT TCEM Climatic Systems for TEXA

‎‎ ‎ ‎

Il Disgelo developed for TEXA two DOT TCEM climatic systems dedicated to electric motor and electric drivetrain testing: a 1.5 m³ chamber for E-Motor applications and a 6.0 m³ system with separate ACU for e-Axle, powertrain and larger systems.

Both configurations allow temperature and humidity to be controlled directly around the DUT while maintaining integration with dynamometers, cooling circuits and data acquisition systems.

‎

Developed Solution

The 1.5 m³ chamber is designed for integration with a test bench and dynamometer, with the air-treatment and refrigeration units installed externally and connected through flexible ducts.

The 6.0 m³ system uses a modular structure with a separate ACU, developed for larger DUTs and higher thermal loads.

The solution includes:

• 1.5 m³ and 6.0 m³ systems;
• −40/+125 °C temperature range;
• humidity up to 95% RH;
• temperature change rates up to 4 K/min;
• integration with dynamometers and test benches;
• feedthroughs for shafts, wiring and fluids;
• DUT thermal-load management;
• CliMaLogic® control;
• integration with external data acquisition systems.
