TT65 PRO

Overview

Currently the second largest in the world, TT65 PRO is the biggest wind tunnel among economically feasible ones. Its exceptional size and innovative design can accommodate larger teams and more complex manoeuvres, allowing athletes to push the boundaries of their skills and showcase the true potential of indoor skydiving. Oriented to prestige projects, where business is secondary to vision opportunity and publicity. Best for government ventures aiming to leave a long-lasting legacy.

The impressive 6.5-meter-diameter flight chamber makes TT65 PRO an ideal venue for world championships and other high-class indoor skydiving sport events. 10 meters of frameless chemically strengthened glass allow superb transparency and extreme reliability. The glass section is divided into two equally tall levels: the bottom one is cylindrical while the upper one is conical.

To maximize the power and make this wind tunnel suitable for advanced military training, TT65 PRO is equipped with 6 extra-large axial fans with carbon fiber blades. Positioned in the vertical air ducts, the axial fans provide the necessary power without compromising energy efficiency and generating more noise. As a result, despite its size TT65 PRO is an environmentally friendly solution with reduced operating costs. Moreover, the minimal noise emissions make it possible to incorporate TT65 PRO into challenging settings.

As all the wind tunnels by Tunnel Tech, TT65 PRO features a list of important safety enhancements. 1.5 flight chamber diffusion ratio, specially designed safety net with near-the-wall deflection, and a curved flight chamber portal prevent injuries even during the most extreme activities.

For the comfort of the flyers, TT65 PRO’s design includes both an outright ventilation system and an optional active cooling system. The ventilation ensures power-efficient operation whenever the outside temperatures are below 30°C adding up to 35% to energy savings. The hollow turning vanes are used for turbulence-free cooling in hot climate zones. None of the systems affect the airflow quality, thus allowing the best performance with maximum comfort.

TT65 PRO stands as an exceptional solution, tailored to meet the demands of the most ambitious and visionary projects. Whether you’re envisioning a large-scale entertainment complex, a world-class sports training facility, or a cutting-edge military training centre, TT65 PRO is your reliable choice in turning ambitious ideas into remarkable realities. It unlocks opportunities for creativity, performance, and safety that were previously out of reach, ensuring that your venture will set new standards and leave a lasting impact.
