Passive high-performance thermal management for defence platforms, equipment and logistics

Thermal Stability for Mission-Critical Systems

Modern defence systems increasingly rely on temperature-sensitive technologies – batteries, electronics, sensors, medical supplies and energetic materials. Extreme temperatures reduce performance, shorten component lifetime and compromise mission readiness.

va-Q-tec provides passive thermal protection technologies based on Vacuum Insulation Panels (VIP) and Phase Change Materials (PCM).

No external power
No moving parts
No failure risk

Conventional thermal management systems rely on complex active components such as compressors, fluid circulation, and electrical heaters. These approaches significantly increase power consumption, system weight, and the risk of mechanical failure. va-Q-tec eliminates these vulnerabilities with advanced passive thermal protection technologies that operate entirely without external energy input.

Proven Performance

Increased system endurance (even at extreme temperatures)
Reduced infrared signature
Independence from external power supply
Increased component lifetime
Reliable mission readiness

Proven Performance

Vaccine transport

The worldwide distribution of the Coronavirus vaccine was considered an enormous logistical challenge, with the ‘last mile’ posing the greatest difficulty. In Uruguay, the government was confronted with the specific problem of distributing vaccines across multiple temperature ranges, which was particularly difficult in remote regions with limited infrastructure. va-Q-tec’s innovative boxes and services were the key solution that ensured a safe and reliable nationwide supply in this critical mission.

More Information
Demonstrated logistical capability through the successful management of over 600,000 mission-critical units.
Ensured full medical effectiveness by maintaining a 100% stable thermal environment without any deviations.
Increased operational flexibility by enabling the use of any standard vehicle for mission-critical transport.

Endurance for HALE UAVs

High-Altitude Long-Endurance (HALE) platforms face critical battery degradation in stratospheric cold. By integrating va-Q-pro insulation into a leading solar UAV, the system was able to harness its own process heat, creating a stable thermal environment without consuming any power. This key innovation eliminated the need for active heaters and enabled a new world record in unmanned endurance: 625 hours (over 26 days) of non-stop flight at an altitude of over 21 km.

Enabled over 625 hours of continuous, non-stop flight for persistent mission coverage and surveillance.
Ensured full system functionality in extreme stratospheric conditions of -54°C and over 21 km altitude.
Optimized the energy budget by eliminating the need for active heaters or complex thermal hardware.
