The Maastunnel is a monumental tunnel in the heart of Rotterdam. Construction started in 1937 and having opened in 1942. It is the oldest tunnel in the Netherlands and passes under the Nieuwe Maas river and is located west of the centre of Rotterdam as a part of the Rotterdam Tunnel Traverse. The closed section of the tunnel is 1,070 metres long and it has two tubes, each with two lanes. There is also a separate tube for cyclists and one for pedestrians.
RE-BUILD THE MONUMENT
The recent overhaul and upgrade of the tunnel involved both structural and technical aspects, amongst which a major alteration of the tunnel ventilation. The importance and complexity of the job to preserve the monument was further stressed by new regulations. This entailed implementation of a longitudinal ventilation system to create safe conditions for the evacuation of people in the event of a tunnel fire and to provide fire brigades with smoke-free attack routes.
RELIABILITY FOR LIFE SAFETY
NOVENCO Building & Industry supplied and installed tunnel fans firstly as a temporary measure during the construction phase and subsequently also for permanent use. The installation consists of NOVENCO’s round tunnel fans type AUR 1250 and rectangular fans type ARC 710, which are specially designed, space-saving jet fans for tunnel profiles with minimal available installation height. In conditions where installation space for tunnel jet fans is limited, the NOVENCO rectangular fans play an essential role when designing ventilation and smoke control solutions. And last but not least, the rectangular range of tunnel jet fans provide a lower sound level, which ensures better conditions and driving comfort in the tunnels.
Both installed tunnel jet fan types are well known for an uncompromising quality and more importantly, reliable in case of fire.
The re-opening of the Maastunnel after two years of reconstruction and renovation aroused a lot of interest around. As it was stated in the Dutch newspaper AD: ‘The Maastunnel passed its final exams. In case of fire, there will occur a storm’ and in this case the storm is guaranteed by NOVENCO’s reliable jet fans.
The system supplied and installed by NOVENCO Building & Industry is a mechanical ventilation system which executed as a longitudinal ventilation and ventilates in traffic direction. The ventilation system is dimensioned for pollution ventilation, and guarantees effective ventilation and smoke control in case of a fire. The ventilation system consists of:
- 9 pcs round NOVENCO AUR 1250
- 5 pcs rectangular NOVENCO AUC 710 tunnel jet fans

The Volkswagen Group is Europe’s largest automobile manufacturer with production sites in seven European countries. With the group-wide future program “Strategy 2025”, Volkswagen wants to get fit for the future with the vision of becoming a world-leading provider of sustainable mobility. Sustainable means also responsible care for the environment.
Sustainable growth is the basis of medium-term future planning and the associated increase in value and image of any company. In that context, the new generation of air handling units with axial fans can contribute greatly in all areas of ventilation and air conditioning.
Since the beginning of 2017, Volkswagen has been intensively investigating the technical possibilities of high-efficiency axial fans and has carried out a whole series of tests, measurements and practical trials. At the beginning of 2018, it was time for the next step: implementation of the obtained results and knowledge in new air conditioning technology. Two production sites in two countries had air handling units with new technology and highly efficient axial fans installed – at Porsche in Stuttgart/Zuffenhausen, Germany and at Volkswagen Navarra in Pamplona, Spain.
- AHU MANUFACTURER: TRUBEL KLIMATECHNIK
- INSTALLATION LOCATION: PAMPLONA, SPAIN
- NUMBERS: 3 AHUs WITH 80,000 m³/h EACH and 3 AHUs WITH 60,000 m³/h EACH
- TOTAL CAPACITY: 420,000 m³/h
VOLKSWAGEN NAVARRA, PIONEER AND ROLE MODEL FOR THE USE OF SUSTAINABLE VENTILATION TECHNOLOGY
Volkswagen Navarra assumes daily responsibility for the environment, safety and society. Thereby resource management and emissions receive special attention. Through innovation and impressive planning at the site, the goal is to continuously reduce energy consumption and the associated CO2 emissions. For this strategic interest, the new device technology with the new ZerAx® axial fans was deliberately chosen as a solution for the renewal of the ventilation in the assembly hall.
"The demands placed on the air conditioning of buildings increase steadily. Axial fans can make a significant contribution to combining technical requirements with sustainable building design. The new trend-setting AHU technology has fully met all expectations."
Asier Matorell, Factory Planning Manager, Volkswagen Navarra and Axel Rossmannek, Head of Supply Planning Volkswagen Wolfsburg
THE VOLKSWAGEN PROJECT
The ventilation had to be completely renewed for one of the largest production buildings of the factory. Higher air volumes were needed and the space available for the installation of the equipment was insufficient. Therefore, a new installation location for the AHUs had to be found on the roof. The large 80,000 m³/h units were placed on a steel platform on the connection between two buildings. In addition to saving energy, the criteria unit size, weight saving and noise reduction were therefore also key requirements.
A NEW AIR CONDITIONING GENERATION
The high demands could only be met with the new generation of air handling units, in which the highly efficient axial fans from NOVENCO were optimally utilized. The last equipment was put into operation in mid-December and exceeded all expectations.
The ZerAx® axial fans currently represent the world’s leading fan technology with fan efficiencies of up to 92%. NOVENCO, however, went one step further by optimizing the ZerAx® even more for use in the air handling units.
