Duol air generators are specially designed and engineered for pressostatic and fixed structures.

Benefits of Duol air generators:
- Improved modulating system (saving up to 35%)
- Smart energy-saving mode
- High efficiency heat exchanger
- Mounted on anti-vibration basis - silent operation
- Insulated sandwich panels resistant to extreme low temperatures
- Reduced hot air stratification

Special De-stratification system improve temperature distribution in the space and reduce the time needed to reach the Ta, this in turns reduce the time the heaters are turned on.

Emergency unit

Reliability and safety are the most important features of Duol structures, and the emergency source of power is a critical item that must not be left to chance. Emergency unit automatically starts when the pressure inside the dome is low or the main power is interrupted or in high wind speeds. Our system of double engine diesel and electric providers a substantial savings – 50% of energy the electric operational system under normal atmospheric conditions (windless, snow, heating) and can maintain the pressure inside the dome instead of the main generators.
