The FKFS operates three climate test benches with different performance ranges, which can be used for a wide variety of tests. These can be used, among other things, for thermal management and climate comfort, contamination investigations, as well as for performance measurements and component function tests. Depending on the test bench, there are different options for controlling air temperature, humidity, and irrigation, allowing flexible adjustment for customer-specific test scenarios.

The Climatic Wind Tunnel and the Thermal Wind Tunnel are Göttingen type wind tunnels including powerful 2-axis dyno test benches. Here, a wide range of different full-vehicle tests can be conducted independently of season and weather conditions, and driving tests can be realistically simulated. While the Climatic Wind Tunnel is primarily used for thermal tests in normal to hot temperature ranges, the thermal wind tunnel allows for the investigation of all aspects of rain simulation and waterproofing.

The climate chamber can be used in a temperature range from −35 °C to 55 °C and, taking into account sun simulation, can be used for investigations of interior comfort and air conditioning.
