High Altitude and Climate Test Bench

Reproducible measurement results under extreme conditions are getting more important in the engine development. The high altitude and climate test bench at St. Valentin covers a large spectrum of possibilities. It is possible to perform all investigations, which are necessary for the development or application of extreme altitudes up to 5000 m above sea level.

The temperature in the test chamber can vary between -30°C and +50°C as needed. In addition it is also possible to regulate the humidity. Beyond stationary programs, the test bench is able to perform transient driving cycles as well as customer specific test cycles.
