The Samruddhi Expressway, a crucial link connecting Mumbai and Nagpur, is a key driver of socio-economic development in Maharashtra
Danfoss Fire Safety has successfully installed its state-of-the-art SEM-SAFE high-pressure water mist fire protection system in the Samruddhi Expressway Tunnel in Maharashtra, India. This installation marks a significant advancement in fire safety technology and infrastructure, aiming to ensure a secure environment for travelers and protect the tunnel structure.
The Samruddhi Expressway, a crucial link connecting Mumbai and Nagpur, is a key driver of socio-economic development in Maharashtra. At the heart of this mega project is the 8-kilometer, 3-lane Samruddhi tunnel, which allows travelers to traverse the Western Ghats mountains in under 10 minutes. Reliable fire protection is essential for such infrastructure, leading to the selection of Danfoss Fire Safety’s SEM-SAFE system for this project.
Tunnel fires can escalate quickly, posing severe risks to life and infrastructure. To address this, the Samruddhi tunnel features 26 cross-passages for emergency evacuation and 54 ventilation fans per tube to maintain optimal airflow and smoke clearance. The adoption of the SEM-SAFE high-pressure water mist system, a cutting-edge technology, further enhances fire suppression and impact mitigation.
“Pioneering the implementation of our SEM-SAFE high-pressure water mist system in the Samruddhi Expressway Tunnel is a testament to Danfoss’s commitment to innovation and safety. We are proud to be involved in a project vital to the development of Maharashtra, ensuring that road users can travel with peace of mind while preserving the environment for future generations,” said Qusai Alasad, Global Manager for Transportation Infrastructures at Danfoss Fire Safety.
“I am honored to witness the successful implementation of our SEM-SAFE high-pressure water mist fire protection system in the Samruddhi Expressway Tunnel. This milestone showcases Danfoss Fire Safety’s unwavering commitment to pioneering safety solutions and our dedication to elevating infrastructure safety standards,” added Poul Harder, CEO of Danfoss Fire Safety.
The high-pressure water mist system is harmless to humans but highly effective against fires. Test results indicate that it efficiently suppresses even deep-seated or hard-to-reach fires, providing a cooling capacity up to seven times greater than traditional sprinklers and effectively preventing re-ignition.
The SEM-SAFE system covers both tubes of the tunnel and consists of high-pressure water mist pump units, section valves, nozzles, pipes, and fittings. The high-quality stainless-steel components and energy-efficient high-pressure Danfoss pumps contribute to the system’s durability and long lifecycle.
Designed with sustainability in mind, the SEM-SAFE system uses minimal water, aligning with the project’s commitment to environmental preservation, especially given its proximity to the UNESCO World Heritage Site of the Western Ghats.
In addition to supplying the system, Danfoss Fire Safety provides comprehensive technical design, engineering capabilities, and site supervision to ensure smooth project handling and support. The contractor for the Samruddhi Tunnel is Afcons Infrastructure Limited, one of India’s largest infrastructure construction companies.
Danfoss Fire Safety’s SEM-SAFE high-pressure water mist system sets a new standard for fire protection in the Samruddhi Expressway Tunnel. By delivering efficient and innovative solutions, Danfoss Fire Safety continues to offer unparalleled performance and cost-effective systems.
