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.
