10000 m2 Air Dome, 2024

Smart energy integration

Smart energy integration

Pioneering air dome solution that seamlessly integrates solar panels with high-efficiency HVAC systems — inspired by renewable energy sources, including geothermal — for truly sustainable operation.

ADVANCED AIRFLOW TECHNOLOGY

Optimized Airflow

The advanced inflation-heating system ensures structural stability, even distribution of fresh air, and prevents warm air from accumulating near the ceiling. The destratification system pushes warm air down towards the floor, reducing energy consumption and enhancing comfort.

Air conditioning system

Air conditioning system

Advanced cooling and insulation system maintains a comfortable indoor climate even in extreme heat. Stable temperature and fresh air even at outdoor temperatures up to 70°C.

TESTED IN THE HOTTEST CLIMATES

Proven Performance in Extreme Heat

DUOL air domes withstand extreme temperatures in the Middle East, Gulf countries, Africa, and South America. From Saudi Arabia to Egypt, our structures ensure a comfortable indoor environment even in the most intense heat.

Extreme conditions, proven solutions

DUOL air domes withstand extreme temperatures, strong winds, and heavy snow loads. Tested in the most demanding climates –from Arctic cold to desert heat.

Kamchatka, Russia
