Large Climatic Chamber

The Large Climatic Chamber features an exceptionally long test section capable of accommodating vehicles up to an articulated bus. It is equipped with a 900-horsepower Mustang chassis dynamometer and a solar array to simulate sunlight. The chamber can also connect to the Climatic Wind Tunnel (CWT) and the Small Climatic Chamber (SCC) through an inter-chamber door, creating a three-chamber testing configuration for larger or more complex test setups.

Key features

  • Ideal for snow testing, featuring advanced snowfall simulation capabilities and an exceptionally long test section for full-size vehicles, including articulated buses.
  • Temperature range from -40°C to +60°C with 5% to 95% relative humidity. 
  • Specialized snowfall simulation system.
  • Equipped with a chassis dynamometer.
  • Solar simulation system with irradiance up to 1,200 W/m².
  • Inter-chamber door connecting to the Climatic Wind Tunnel (CWT) and the Small Climatic Chamber for integrated three-chamber testing.
  • Direct dry-transfer connection to the Climatic Wind Tunnel (CWT) and the Small Climatic Chamber (SCC).
  • Complete suite of ancillary systems supporting conventional, electric and hydrogen-powered vehicles.
