DOT TCEM-40 | 2.9 m³ – eAXLE

CLIMATIC CHAMBER

DOT TCEM-40 | 2.9 m³ – eAXLE

Climatic chamber designed for thermal and climatic testing of e-Axle systems and integrated motor-transmission assemblies, developed for high-precision automotive applications and direct integration with dynamometer benches.

The 2.9 m³ configuration provides optimized internal volume for functional and endurance testing of complete assemblies, ensuring stable thermal control and repeatability of cycles under dynamic operating conditions.

Structural Architecture
