World’s biggest tunnel filter system uses NOx technology

6 April 2006

Madrid Calle 30 will not only be the world’s biggest underground project, it will also be furnished with the first filter system using NOx technology – AND we will be the ones to supply the complete turn-key plants!

 

 

The Spanish construction company “Ferrovial” decided to invest into two ECCO plants for 450 m3/s and 570 m3/s airflow, including our ECCONOxCat to reduce the harmful nitrogen dioxide (NO2). We are looking forward to realizing such a great project!
