TUNNELS It is essential that reliable ventilation systems are used to provide safety for the user throughout the years. Tunnel ventilation may be natural or forced and in the latter case, fans must be installed to generate the proper air movement to maintain safe conditions in comfort mode as well as in event of an emergency. FUNCTIONS OF THE VENTILATION FOR TUNNELS Ventilation system in comfort mode (healthy air): • Maintains health conditions such as adequate temperature or humidity. • Supplies fresh and clean air from the outside. • Extracts air pollutants. Ventilation system in...

VENTILATION SYSTEMS Ventilation systems may be configured based on different key elements such as the type of tunnel, length, slope or traffic volume: SEMI-TRANSVERSE VENTILATION

SOLUTIONS WITH JET FANS Ventilation systems for tunnels with jet fans are the most widely used. Kinetic energy is used to remove stale internal air (gases and smoke generated by vehicles in road tunnels, railway and underground tunnels). These can be unidirectional or reversible fans. Unidirectional type fans are designed to optimise performance in one direction (forward), while reversible fans provide the same performance but in both directions. Since the environmental conditions inside some tunnels may be highly corrosive, the material used for manufacturing these fans must be appropriate...

ANCHORING AND SAFETY SYSTEMS These fans are mounted to the ceiling of the tunnel using anchoring systems designed and calculated specifically for each project. The anchoring systems are equipped with anti-vibration units that are selected according to the fan’s weight and thrust. Several anchoring systems are used, adapted to the specific conditions of each tunnel. • Temperature sensors in windings and bearings (PT100, PTC) • Vibration sensors • Heating elements Airflow sensors Deflectors Grilles Power switches PRODUCT NOMENCLATURE THT/IMP O THT/IMP: Jet fans with a long reach Airflow...

AXIAL FAN SOLUTIONS Axial fans are essential for renewing indoor air and for extracting smoke in the event of fire. They are installed in ventilation shafts that connect the tunnel with the outside, allowing to supply fresh air inside the tunnel. • • • • • • High performance fans in terms of quality and reliability. Manufactured in accordance with European standards (EC marking and EN 12101-3). Especially designed for tunnels. Easy to maintain. Fully reversible fans. Horizontal or vertical installation.
