Lehavot Kitchen Shield WCK Kitchen Hood Fire Suppression System

The Lehavot Kitchen Shield WCK (Wet Chemical Kitchen) is a pre-engineered, automatic fire suppression system manufactured by Lehavot Fire Protection Systems for commercial, institutional, and industrial kitchen environments. Designed to combat high-temperature Class F / Class K cooking oil and fat fires, the system continuously monitors kitchen hoods, plenum spaces, and underlying appliances (deep fryers, ranges, griddles, and woks) via a mechanical detection network incorporating fusible alloy links. Upon flame ignition or thermal threshold breach, the links separate, releasing a pressurized mechanical actuator that discharges a specialized potassium-based wet chemical liquid through optimized spray nozzles. The agent rapidly smothers flames, cools burning fats, and reacts with hot grease to form a saponification foam blanket that prevents re-ignition. The system concurrently triggers an automatic mechanical or electrical gas/electricity shut-off valve to isolate energy sources, features manual mechanical pull stations, and holds full UL 300, NFPA 17A, NFPA 96, LPCB, and CE certifications.
