Tunnel Solutions for Fire Suppression
Unlike traditional structures where fires can be fought from outside, road tunnels require durable interior fire suppression systems to combat the unique hazards of passenger and cargo vehicles. A dependable fire suppression system protects the tunnel structure and reduces the severity of the fire, allowing occupants to exit safely and giving first responders time to enter.
We offer a complete road tunnel fire sprinkler system with innovative products and a consultative approach. Our TNL280 pendent nozzle stands out with its large K-factor, allowing for a wide coverage area that reduces the number of nozzles needed and lowers installation costs. The downward spray pattern is less impacted by the powerful ventilation systems essential for smoke and heat removal, providing the TNL280 a distinct advantage over mist-based systems and sidewall nozzles. The TNL280 is offered with Reliable’s RASCO500 ceramic coating for exceptional corrosion resistance and improved durability.
Road tunnels are classified as high-hazard areas requiring remote control system management to prevent potential flooding. Our DDV Deluge Valve’s remote resetting capability enables trained personnel to activate and deactivate the system from a safe location. Pressure-regulating trims ensure optimal water pressure, even in long tunnels with extensive piping.
We partner with clients to create tailored solutions for complex road tunnel fire protection challenges. Our team of experts will help you select the right products to design a system that meets your tunnel’s specific needs.
