A drive-in altitude test chamber is a special test facility for testing the effects of different altitudes and climatic conditions on complete vehicles and individual components.  

The chamber simulates air pressures as they occur at different altitudes above sea level. This can be combined with climate simulations for all climate zones on Earth, enabling vehicle manufacturers to simulate a wide variety of conditions in one location. Altitude test chambers are used worldwide in the automotive industry.  

An altitude test chamber is also referred to as an altitude chamber, pressure chamber, altitude climate chamber, or  

altitude environmental simulation chamber. 

Functionality and safety tests on vehicles and components are carried out in a drive-in altitude test chamber 

under various altitude and climate conditions.  

This includes checking the engine and battery cooling systems. 

Drive-in altitude test chambers allow tests under different air pressure and climatic conditions to be conducted in one location. This reduces costs and helps vehicle manufacturers to make vehicle development and quality assurance more efficient.  

To achieve comparable test results, altitude test chambers must provide reliable and reproducible simulations of the required parameters, such as altitude and climate. Depending on requirements, the altitude test chambers meet various specifications and international standards of the automotive industry.  

Air pressure decreases by 25% up to 2,500 meters above sea level and by 50% up to 5,000 meters. For precise and reliable test results, altitude test chambers are equipped with control systems that ensure stable and homogeneous climate control and air pressure adjustment.  

The required climatic conditions are achieved with pinpoint accuracy. The tried-and-true, versatile control and regulation system also contributes to this.
