It can be seen easily from a long distance, and also offers a perfect means of advertising. The surface of 200 m² on the balloon envelope can be individually designed, so that a logo or advertisement can hardly be missed. The impressive appearance of the balloon combined with your logo creates powerful, lasting attention to your brand.

Operational FAQ
What are the requirements on the installation site?

The site should be free of obstacles higher than 3 m (9.84 ft) within a diameter of 40 m (131.23 ft). A centered funnel of 90° opening towards the sky must be completely free of obstacles. Eight restraint points, evenly distributed around the balloon, with a radius of 20 m (65.62 ft), must be freely accessible. The winch further requires a 3×380 V power supply.

How sensitive is the system with respect to wind speed?

The maximum wind speed for operation is 6 m/s.

Up to what wind speed can the balloon remain inflated while anchored to the ground?
