North America Wind Tunnel

North America Wind Tunnel

Our climatic wind tunnel provides fast, accurate results without blowing your testing budget.

Cost effectiveness and accuracy are factors everyone looks for in a vehicle climatic wind tunnel testing facility. Air International is both cost effective and accurate. In fact, our facility will exceed your expectations. It's independent and secure with a state of the art data acquisition system. Plus, our climatic wind tunnel provides accurate results without blowing your testing budget. We save you money by cutting instrumentation costs and we use a custom LabVIEW based acquisition system so the quality and accuracy of your test data is never compromised. Every necessary component that obtains test data from your vehicle is accessed through a 200-channel patch panel. Then all of the test data is processed and stored for all of your HVAC or PTC testing needs. We can perform custom tests easily, because we can program virtually any programmed test cycle including simulated hill profiles for any passenger vehicle. A complete formal report is automatically generated in Excel format. Each report includes raw data, graphs, and heading information that allows for quick data analysis.
