Meeting the Demand for Extreme Conditions in Tunnels

Future projections for the North American tunneling industry are extremely positive. With populations and infrastructure expanding in major cities there is a continued need for more tunnels to move people and freight around efficiently. Air quality, air control and in the worst scenario smoke control within road and rail tunnels is a huge consideration for design engineers. Dependable equipment needs to be specified for these demanding tunnel environments.

Ruskin® tunnel ventilation dampers are relied upon worldwide for controlling and supplying air to commuters underground. These specialized dampers provide fire protection as well as purge and smoke control during emergency conditions. By using a combination of stainless steel, galvanized steel, and aluminum, Ruskin tunnel dampers can withstand the harshest conditions, including the constantly changing environments found in most tunnels.

Every damper is built with performance in mind and is designed to meet or exceed AMCA (Air Movement Control Association) specifications. Since most industrial systems cannot be shut down for normal periodic maintenance, our products are designed to support options such as exposed linkages and outboard bearing packages. These facilitate easy maintenance while the system is operational.

Each damper is thoroughly checked, tested and cycled before it is delivered to site. In addition to this and to make certain each damper performs to specifications, leakage and performance requirements are verified through Ruskin’s Research and Development department. Ruskin has developed an on-site AMCA registered air performance laboratory. Located in Kansas City, Missouri, this test facility has three high capacity wind tunnels. These test tunnels help Ruskin simulate demanding wind and air handling situations and are ideal for testing leakage and pressure drop replicating tunnel environments.

Ruskin works with a variety of materials, including galvanized steel, aluminum, stainless steel and fiberglass in order to match our customer’s exact specifications. By molding and forming these materials, we can develop dampers to fit almost any application.
