NSBT Selects TFD80
Ruskin is supplying the TFD80 Heavy Duty Combination Fire/Smoke Dampers for Tunnel Ventilation. There are 400 assemblies in the project, 359 of which are 3m x 2m and mounted in the tunnel ceiling for emergency smoke ventilation. The dampers are built in G165 galvanized coating steel with special epoxy coating in matt-black finish, per the requirements of the specification.
Together with Ruskin’s customer, United Group Infrastructure, and Ruskin’s representative to Australia, Applied Technology Integration, Ltd. of Hong Kong, a new thermal enclosure for the Valvcon electric damper actuators has been developed, to provide continued operation at 300 deg. C for 2 hours. This enclosure will become Ruskin’s standard for tunnel projects throughout the world when electric actuators are required.
Ruskin is proud to be associated with such a prestigious and important project on the Australian Continent.
2009 Project On Track
Dubai Metro is a fully-automated rail tunnel passing below the city of Dubai in the UAE. Currently, the Red and Green Lines are under construction, with more lines in the planning stages. The $4.2 billion Metro rail system is on target to open in September 2009, according to the Road Traffic Association (RTA), which is managing the project.
The main part of the system is underground, with elevated viaducts on the outskirts. Around 7,000 people are working around the clock on the project at different sites across the city. Once completed, 87 fully automated, driverless, trains will run on the Red and Green Lines, which will comprise over 75 kilometers of track. Nearly 2 million people will be able to use the Metro when it is completed.
Tunnel Ventilation Dampers
Ruskin is supplying the TFD80 Heavy Duty Combination Fire/Smoke Dampers for Tunnel Ventilation. There are 189 assemblies in the project with 111 of them in 4m x 4m size, all operated by electric battery-backup actuators by Valvcon, with special thermal enclosures to allow operation at 250 deg. C for 2 hours in emergency situations.
Ruskin is working very closely with our United Kingdom office and the customer, ETA/SET joint venture in Dubai on this most prestigious project.
