Zitrón carried out the most challenging high temperature test for tunnel axial fans

We are very proud to announce that on 4th June 2020, Zitrón successfully carried out the most challenging high temperature test to date on a tunnel axial fan: 600 ºC for 120 minutes.

Zitrón Hight Temperature Test 600, 2 hoursThese fans will be installed at the Ursynów tunnel, on the Warsaw southern bypass (Poland). Zitrón has been awarded the contract for the design, manufacture, delivery and commissioning of the complete tunnel ventilation system on this project.

The fan was tested at Applus+ TST Laboratories according to standard EN-12101-3. Test conditions and measurements were strictly controlled, monitored and recorded. The test was broadcast live via a streaming platform, and followed 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 during 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 exhaust 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.
