On the 04/06/2020 Zitron successfully carried out the most challenging high temperature test to date on a tunnel axial fan: 600 ºC for 120 minutes.

These fans will be installed at the Ursynow tunnel, on the Warsaw southern bypass (Poland). Zitron has been awarded the contract for the design, manufacture, delivery and commissioning of the complete tunnel ventilation system for this project.

The fan was tested at Applus+ TST Laboratories complying with standard EN-12101-3. Test conditions and measurements were strictly controlled, monitored and recorded. The test was broadcast live via a streaming platform and monitored by inspectors and the project management team based in Warsaw.

The goal of this test was to assure the proper fan performance at 600 ºC for at least 2 hours. This is an important and demanding requirement, taking into account that in case of fire inside the tunnel, the axial fans would have to remove the hot fumes, keeping escape routes free of smoke to allow the evacuation of users, and also enabling the access of fire and rescue services.
