▶Tested safety ▶▶ TROX tunnel dampers for underground transport systems

▶The art of handling air ▶ ▶ TROX understands the art of competently handling air like no other company. Founded in 1951, TROX develops sophisticated components and systems for room air conditioning, as well as re and smoke protection. Due to extensive research and development, TROX has, for years, been one of the sector’s leaders in technology. TROX is an owner-run, globally active company with a turnover of € 350 million in 2010. With 25 subsidiary companies in 22 countries and 13 production sites in 11 countries, the company has efcient, customeroriented manufacturing capacities that guarantee...

TROX is a certied company and active member in the Research Association for Underground Transportation Facilities (Studiengesellschaft für unterirdische Verkehrsanlagen e. V. = STUVA). STUVA is involved in independent, basic research and publication of scientic knowledge in regard to safety in underground transport systems. The International Center Fire Protection (Internationales Center Brandschutztechnik = ICB) is the new testing, research, and development centre of the TROX GROUP. In the most state-of-the-art laboratory for re protection technology in Europe, newly developed products are tested...

▶ When safety has top priority ▶▶ In comparison with open spaces and buildings, the escape possibilities in underground transport systems are very largely limited. If safety standards are not observed, a re can have catastrophic consequences. Smoke / temperature The development of smoke in the case of a vehicle re is relatively harmless outdoors. In a tunnel, however, it can have deadly consequences. The spreading speed of poisonous re gases within the tunnel far exceeds the human speed of escape. Most people who have died in res in underground transport systems were usually victims of smoke...

In the case of a re in a tunnel without a smoke extract system, the vehicle passengers have ve minutes at the most to save themselves; after that, the level of smoke development is too high. The period of time available for self-rescue must thus be extended by suitable smoke extract systems that keep the tunnel free of smoke. In addition to helping people save their own lives, smoke extract systems also aid in re ghting. A fast, targeted extinguishing of the re is possible if the development of smoke does not become a major obstruction in the attempt to extinguish the re. The Guideline for the...

▶ Tailored solutions ▶▶ Underground transport systems are generally unique. Standardised solutions in this area hardly exist, not even for tunnel dampers. To recognise and realise potential optimisation, TROX engineers and product managers are available to support their customers in the design phase. This results in project specic solutions that meet all technical and economic requirements. The individual project planning includes exemplary, project-specic service that not only guarantees a permanently high safety standard, but also lowers operating costs and minimises downtimes. The efciency...

▶ Uncompromising safety ▶▶ TROX tunnel dampers are available as a complete solution including the drive motor, thermal insulation enclosure, and, if required, subframe. This guarantees a maximum functional reliability of combined elements. Greater efciency Since only the tunnel dampers in the direct vicinity of the re area are opened, the other dampers must remain closed, sealed as air-tightly as possible to increase the efciency of the smoke extract system and protect the tunnel sections not affected by the re from poisonous re gases. On TROX tunnel dampers, spring-loaded seals allow for the...

▶ Tested quality ▶▶ TROX leaves nothing to chance. To prove the functional reliability of TROX tunnel dampers under realistic conditions, they are subjected to extensive internal and external loading tests. Test reports from national and international testing institutes document the high level of safety. TROX thus fulls the highest standards worldwide. With a certied production process, TROX guarantees production quality without compromise all over the world. TROX tunnel dampers are manufactured in Germany and Malaysia. From the goods inwards inspection to delivery of the nal product, all processes...

If you add up the lengths of all tunnels in Germany, you will get a total length of 1,320 km. 640 km of underground/urban railway tunnels 480 km of long-distance railway tunnels 200 km of road tunnels In Germany, this corresponds to a distance of a trip from Kiel to Munich and back. At present, 51 tunnels are under construction. In the next 10 years, an additional 515 km are planned. Europe has a total of approximately 15,000 km of trafc tunnels. This corresponds to the distance from Lisbon to Moscow and back. Spain and Italy have the most tunnels. 15,000 km in Europe 22,500 km in Asia 100 km...

▶ Challenges mastered ▶▶ Fire protection retrot for the Elbe Tunnel in Hamburg, Germany After the devastating re catastrophes in the Mont Blanc tunnel, the Tauern tunnel and the Gotthard tunnel, the EU reacted by enacting Directive 2004/54/EC “Road Tunnel Safety in the TransEuropean Road Network,” which set new standards in regard to re protection. A comprehensive retrot of the rst, second and third tubes of the 3,325 metre long tunnel was started in early 2009 to comply with the new directive and to improve safety in the Hamburg Elbe tunnel. TROX is supplying 410 tunnel dampers for smoke extract...

▶ Full scale safety testing ▶▶ Test tunnel of Fundación Barredo, Spain Tunnel Safety Testing S.A. operates the “Centro Experimental de San Pedro de Anes” testing station of the Fundación Barredo foundation in Siero in Asturias, Spain. In the 800m-long tunnel, the use of ventilation systems during a re, amongst other things, is being tested in full scale. Fans of normal designs and sizes are being tested in the test tunnel. The tests are performed according to EN 12101-3:2002. TROX equipped the test tunnel with 88 Type JFP tunnel dampers with electric actuators. Project: Owner: Specialist consultant:...
