Wagner Rail has expanded the WAGNER Group’s FirExting portfolio with the launch of Water Mist Compact, a water mist-based fire suppression system for use in passenger areas in railway carriages.
The system is said to provide high efficiency performance with a reduced space requirement and easier integration and maintenance.
Water mist systems work by releasing micro-fine water droplets that evaporate very quickly as mist, drawing heat energy away from a fire. This enables fast, effective, and gentle fire suppression with low water consumption.
“Thanks to their low water consumption, water mist systems cause very little secondary damage, making them ideal for areas where operations need to resume quickly after a fire,” explains Dr. Markus Müller, Managing Director of Wagner Rail.
“Our latest development goes one step further: it is our smallest and lightest water mist system. It can be installed in a more compact space while delivering the same performance. Both planning and integration into the vehicle are simpler than with conventional systems.”
According to Wagner Rail, the compact water mist system houses the water needed for fire suppression and the nitrogen gas required for atomisation in a single container. This is said to eliminate additional components and piping typically found in traditional water mist systems.
This design saves installation space and weight as well as reduces the number of interfaces with the vehicle. It also simplifies planning and execution of the installation process.
After an activation, the system can be replaced quickly as the containers can be kept in stock as compact replacement parts.
The system is claimed to comply with ARGE Part 2 and UNI 11565:2021, suiting it for use internationally. Since the containers can be heated or insulated, this solution is also suitable for demanding applications and operates reliably even at very low temperatures.
“Ultimately, what matters most to operators is a comprehensive package that combines safety, reliability, and cost-effectiveness,” Müller adds. “Our technology stands out for its high effectiveness, low impact on the interior, and excellent retrofitability. This makes it ideal for both existing fleets and new vehicle designs.”
Wagner Rail has begun implementing its first projects using the Water Mist Compact system, which will be showcased at InnoTrans in Berlin from September 22 to 25.
