Welcome to Flytec Balloon, the ballooning branch of Volirium*. Volirium is the Swiss company that built the very first electronic variometer for free-flying pilots, over 35 years ago. In 1992, we were the first to build a variometer for ballooning with wireless envelope temperature transmission. Since then, we have equipped thousands of balloons with our temperature sensors, our balloon varios are flying all over the world, and at least one of them flew once around the globe in a single flight. Pilots at all levels, from recreational balloonists to commercial operations, all the way to world champions both in hot air and gas ballooning, rely on Flytec Balloon varios.

Balloon varios

We offer several varios that we designed specifically for hot air balloon pilots.


We are here to assist you and help you make the most out of your Flytec Balloon vario.


Varios have a tough life, and sometimes they need some tender loving care to make up for it. We repair Flytec (both Balloon and paragliding/hang-gliding), Volirium, Bräuniger and Naviter varios.
