Wet Chemical Fire Suppression System

Wet Chemical Fire Suppression System — Technical Description: A wet chemical fire suppression system is an automatic, pre-engineered fire protection system specifically designed to detect and extinguish fires involving commercial cooking equipment, grease-laden vapors, and combustible cooking oils. The system typically consists of heat-sensitive detection devices, a releasing mechanism, pressurized agent storage cylinders, piping, and discharge nozzles strategically located within the kitchen hood, ductwork, and over protected appliances. Upon detection of a fire, the system automatically shuts off the fuel and/or electrical supply to the cooking equipment and discharges a potassium-based wet chemical agent. The agent rapidly cools the burning oils and reacts with the hot grease through a process called saponification, forming a foam-like soap layer that suppresses vapors and prevents re-ignition. Wet chemical systems are commonly installed in commercial kitchens, restaurants, hotels, cafeterias, and institutional food service facilities, and are designed in accordance with applicable fire protection standards such as NFPA 17A and NFPA 96.
