Wet Chemical System
A Wet Chemical System is a specialized fire suppression system designed to control and extinguish fires involving cooking oils, grease, and fats. These fires can spread rapidly and require a suppression agent specifically designed to cool burning surfaces and prevent re-ignition.
Wet chemical systems are commonly installed in galley cooking areas on vessels, offshore installations, and commercial cooking environments where grease fires present a significant risk.
We provide professional wet chemical system inspection, servicing, installation, and maintenance to ensure reliable fire protection and compliance with international fire safety standards.
Engineers typically design and install this suppression systems according to NFPA 17A fire protection standards, ensuring effective protection for cooking equipment and ventilation hoods.
How a Wet Chemical System Works
A wet chemical fire suppression system automatically detects heat and chemical discharge mechanisms that respond quickly when a fire occurs.
When excessive heat or flames are detected:
- Heat detection devices activate the suppression system.
- The releasing mechanism triggers the discharge process.
- The system releases wet chemical agent through nozzles.
- The agent reacts with burning grease and oils to form a foam blanket.
- The foam cools the surface and prevents re-ignition.
This process ensures rapid suppression of grease fires, protecting equipment and surrounding structures.
Components of a Wet Chemical System
This system system includes key components that ensure reliable fire protection.
Main components include:
- Heat detection devices
- Expellant gas containers
- Wet chemical agent containers
- Manual and automatic releasing devices
- Distribution piping networks
- Hose assemblies
- Discharge nozzles positioned above cooking equipment
- Alarm signals and system control units
- Auxiliary equipment connected to the suppression system
These components work together to ensure quick system activation and effective fire suppression.
Wet Chemical System Inspection and Servicing
Routine inspection and maintenance keep the system fully operational during fire emergencies.
During scheduled inspection, They also check liquid levels in non-pressurized containers, the expellant gas container(s), the agent container(s), releasing devices, piping networks, hose assemblies, discharge nozzles, signal systems, and all auxiliary equipment connected to the suppression system.
Additionally, the liquid level of all non-pressurized wet chemical containers they checked to ensure sufficient suppression agent is available for effective fire protection.
Regular servicing helps ensure the wet chemical system remains fully operational, compliant with fire safety standards, and ready to respond during emergencies.
Wet Chemical System Inspection Process
Professional servicing follows a structured inspection procedure:
Step 1 – Detector Inspection
Technicians check all heat detectors and detection components..
Step 2 – Cylinder & Agent Verification
They inspect expellant gas containers and wet chemical agent containers.
Step 3 – System Component Examination
Inspect piping networks, hose assemblies, and discharge nozzles.
Step 4 – Control & Signal Testing
Verify system signals, alarms, and auxiliary equipment.
Step 5 – System Readiness Verification
Confirm liquid levels in non-pressurized containers and ensure full operational readiness.
This structured inspection process ensures maximum system reliability and safety.
Applications of Wet Chemical Systems
Engineers install this suppression systems in environments where grease fires present a high risk .
Typical applications include:
- Vessel galley cooking areas
- Offshore installation kitchens
- Industrial cooking facilities
- Food preparation areas
- Commercial kitchen environments
These systems provide reliable fire protection for cooking equipment and ventilation systems.
