Fire Test Gallery                                     
The Fire Test Gallery has a 10 m2 cross section, and its length is 110 meters. The beginning and the end of the gallery is covered with concrete rings, and its middle section consists of hard rock bolted supporting system. The gallery is also served by a 110 KW ventilator with a remote controlled frequency regulator, allowing the control of the air velocity inside the installation.  Remote controlled doors can be opened or closed, according to the ventilation requirements
