DESIGN & INSTALLATION
Since 1946, Koorsen Fire & Security have been protecting restaurants, commercial kitchens, and food trucks from fire. A big part of protecting these kitchens is with installing fire suppression systems over the cooking appliances and inside the exhaust hood systems. We work with all of the major system manufacturers and can design and install a kitchen suppression system to meet your unique needs.
INSPECTION & TESTING
To keep the kitchen fire suppression systems working and ready in case of a fire, inspections are required every 6-months according to NFPA 17A. Our licensed technicians will complete a thorough inspection of your system to ensure everything is in working order and not damaged or obstructed from grease and smoke build-up.
