Watermist Applicator 138

The Watermist Applicator 138 (FI-WMA138) is a further development of the Watermist Applicator 126, engineered to deliver higher cooling capacity and extended reach for electric vehicle (EV) fire suppression. Its increased length enables more effective placement beneath vehicles, allowing responders to cool the battery area directly and limit fire escalation at the source.

Lightweight and mobile, the FI-WMA138 weighs only 10 kg, making it easy for a single operator to deploy in demanding environments such as parking garages, ferries, tunnels, and other confined spaces.

Performance and Application

Designed for direct under-vehicle deployment, the FI-WMA138 applies fine water mist to rapidly reduce temperature around the battery enclosure.

• Targets EV battery fires at the source

• Longer body than the 126 version for improved coverage

• Rapid cooling to slow thermal runaway and reduce spread

• Optimized for confined and high-risk environments

At 4 bar water pressure, each unit produces a minimum of 200 liters per minute, providing strong cooling performance with controlled water usage.
