Individual insulation of the vehicle interior
The successful Austrian ski freerider Fabian Lentsch and va-Q-tec have joined forces to organize an adventure trip to remote regions of the world. The goal was to modify an old Mercedes Benz truck, known for its reliability, into a comfortable and spacious van.
va-Q-tec’s high performance Vacuum Insulation Panels (VIPs) were the perfect solution for the van. The space saving insulation enabled an optimal separation of the temperatures inside of the van and the extreme outside temperatures of the remote ski regions. A total of 40 VIPs with a thickness of 2 cm were installed in the van to ensure the best possible insulation performance with minimum space requirements.
Vehicle factory Bernard KRONE GmbH
The Fahrzeugwerk Bernhard Krone and va-Q-tec wanted to prove with the joint construction of a prototype that a higher insulation value, the reduction of the required generated cooling capacity and CO2 emissions and therefore lower operating costs are possible. The requirement was to maintain the necessary panel strength.
Solution in a prototype:
va-Q-tec’s VIPs were integrated into a PU foam wall of a refrigerated trailer. The energy is now used more efficiently and the K-value was optimized as well.

Solar powered microlight aircraft “Zephyr” for use in the stratosphere
Batteries in solar aircrafts feed the electric motor and are recharged by the solar panels during the day. However, at an altitude of 20 km at temperatures below -50 °C, they are not functional. The old world record for an endurance flight was only 36 hours, because the energy storage devices failed to work at night. In addition, the entire aircraft was only allowed to weigh 50 kg with a wingspan of 23 m. The aim was to achieve the best possible insulation of the battery with the lowest possible total weight of the aircraft.
va-Q-tec’s flexible va-Q-pro “folding box panels” made of one piece are extremely light while still having/guaranteeing best insulation performance. They are only 6 mm thick and can be installed very flexibly. Due to the optimal insulation of their innate warmth the batteries are able to keep themselves at a comfortable temperature. As a result, the team was able to break the old world record for endurance flights. It now stands at 336 hours of non-stop flying at an altitude of over 21 km.
BioServe Space Technologies (Colorado, USA)
A special cooling device, called “Freezer/Refrigerator/Incubator Device for Galley and Experimentation” (short: FRIDGE) was developed for the International Space Station (ISS). It can generate temperatures from below -10 °C to over +48 °C. The aim was to ensure reliable cooling of astronaut food and safe temperature control during scientific experiments.
The functionality and design of the originally used cooling units had to be improved. Among other things, by reducing heat loss, in order to be able to guarantee cooler temperatures.
The foam insulation of the unit was supplemented with vacuum insulation panels (VIPs). Decisive for FRIDGE’s success were the flexible sizes, the durability and the excellent insulation properties of the VIPs.
