Fire fighting system - FineFog™
DESMI’s FineFog™ Fire Fighting System is a low-pressure, fresh-water-based fire fighting solution designed for local protection of high-risk compartments onboard naval, defense, and commercial vessels. Utilizing fine water mist, the system efficiently absorbs heat, suppresses flames, and reduces oxygen in the immediate fire area, ensuring rapid extinguishing performance without excessive water damage. FineFog™ combines technological precision, operational reliability, and compact design to secure vessel readiness in critical conditions.

Design and Technical Characteristics
The DESMI FineFog™ fire fighting solution uses a fixed, low-pressure water mist principle with fresh water as the extinguishing medium. The system distributes millions of small water droplets through precision nozzles, generating a fog-like mist that maximizes surface area and heat absorption. The modular system design includes:
-
Customizable mist-generation units with low-pressure nozzles
-
Compact pump units optimized for vessel integration
-
Corrosion-resistant piping and components designed for marine environments
-
Flexible configuration for local or zonal protection
This design ensures stable performance, ease of maintenance, and long service life, even in confined spaces onboard defense and commercial vessels.
System Efficiency and Safety Performance
FineFog™ achieves superior extinguishing performance through the interaction of fine-droplet water mist and the heat and oxygen balance within a fire zone. The mist droplets:
-
Absorb heat efficiently, quickly lowering ambient temperature
-
Displace oxygen locally, reducing combustion intensity
-
Generate an inerting effect that minimizes the potential for reignition
The resulting combination ensures both effective suppression and safe working conditions for onboard personnel. Because the system operates at low pressure and with minimal water volume, secondary damage and cleanup are significantly reduced compared to traditional systems.
Standards, Compliance, and Reliability
DESMI’s FineFog™ Fire Fighting Systems are developed in accordance with applicable marine and naval fire protection rules. Each configuration is engineered to meet relevant classification society requirements and safety standards for onboard fire fighting. Systems can be supplied in designs tested to recognized marine and naval standards, ensuring compatibility with class and flag authority regulations. Continuous product development secures long-term compliance and operational reliability in all shipboard environments.
