Adjusting air pressure reduces energy consumption and optimizes system performance.
DSV - Dual Ventilation System
Modular fan operation increases reliability and optimizes ventilation.
Advanced Modulation System
Optimized system performance allows up to 35% energy savings.
Enhanced Heat Exchanger
Improved heating efficiency with better energy utilization.
High-Efficiency Condensing Unit
Maximizes heat recovery with energy efficiency of up to 105%.
Smart System Control
Automatically adjusts to external conditions (wind, snow, pressure) for optimal performance.
Quiet Operation Mode
Circular fan with silencers reduces noise for quiet operation.
Versatile Heating Options
Heating available with multiple energy sources: natural gas, liquefied petroleum gas, hot water or steam, electricity, heat pump, biomass, or a combination of sources.
As quiet as an air conditioning unit used in residential houses.
LOW-NOISE ENGINEERING FOR COMFORT
Quiet Operation
DUOL’s inflation system, equipped with advanced sound insulation, ensures a quiet and comfortable environment inside the air dome, without disturbing the surroundings in urban areas.
HVAC System: Chuncheon City, South Korea
10000 m2 Air Dome, 2024
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
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
Designed to withstand extreme snow loads, this structure supports up to 600 kg/m² of snow, ensuring stability even in the harshest winter conditions.
Saudi Arabia
Designed for extreme heat, this air dome maintains a stable indoor climate at +25°C, even when outdoor temperatures reach +55°C.
Hveragerði, Iceland
Designed to withstand strong winds, this air dome endures gusts of up to 200 km/h, ensuring safety and stability even in the most demanding weather conditions.
Helsinki, Finland
The membrane is designed for efficient snow removal - snow does not accumulate on the surface but simply slides off, reducing structural load.
Yamal, Russia
A reference in one of the coldest areas of the world, where an air dome withstands external temperatures of up to -55°C, while maintaining a comfortable +20°C inside.
