The CLWT-067 is a research-quality closed loop wind tunnel that provides a convenient, accurate system for thermally characterizing PCBs and individual components at controlled temperatures from ambient to 85 C. Its test section Dimensions are (L x W x H) 43.1 x 25.0 x 8.9 (inside wall to wall) cm (16.9 x 9.8 x 3.5 inch)

Unlike open loop wind tunnels, the CLWT-067 recirculates internal air. This allows the system heater to quickly warm the air to a specific temperature. The testing of boards and components in hot air is a requirement in some NEBS and other standards. The precise controls and temperature range of the CLWT-067 wind tunnel allow its use for testing heat sink performance and for calibrating air and temperature sensors.

The wind tunnel's test section can be accessed from the top door for mounting and repositioning of boards, components and sensors. Optional internal rail guides provide an easy mechanism to install test specimens of different sizes (e.g., PCB, heat sink). Instrument ports (6) are provided in the side walls of the test section for placing temperature and velocity sensors, such as thermocouples, Pitot tubes and hotwire anemometers.
