Three DOT TCEM Climatic Chambers for Maserati

‎ ‎ ‎

Il Disgelo developed for Maserati a platform consisting of three DOT TCEM climatic chambers dedicated to motor and powertrain testing: two 1 m³ chambers and one 2.7 m³ chamber.

The systems allow temperature and humidity to be controlled around the DUT while maintaining integration with dynamometer test benches, drive shafts, electrical connections and fluid circuits.

‎

Developed Solution

The chambers feature a modular structure designed to simplify DUT installation and integration with the test bench.

The system also integrates nitrogen inerting and oxygen monitoring to increase safety during specific test configurations.

The solution includes:

• 2 × 1 m³ DOT TCEM chambers;
• 1 × 2.7 m³ DOT TCEM chamber;
• −40/+120 °C temperature range;
• 20–95% RH humidity;
• temperature change rates up to 4 °C/min;
• integration with dynamometers and test benches;
• dedicated feedthroughs for shafts, wiring and fluids;
• nitrogen inerting;
• O₂ concentration monitoring;
• overpressure protection;
• CliMaLogic® control;
• Ethernet, VNC Viewer and Modbus TCP/IP.
