TL;DR
An Ansul system is a pre-engineered wet-chemical fire suppression system for commercial kitchens, the brand so dominant that the name covers the category, with nozzles aimed at each appliance, the plenum, and the duct above the cook line. When a fusible link melts or someone pulls the manual station, it discharges a potassium-based agent that saponifies burning grease into a smothering foam and simultaneously cuts gas and power to the appliances.
What it means
An Ansul system is a pre-engineered wet-chemical fire suppression system for commercial kitchens, the brand so dominant that the name covers the category, with nozzles aimed at each appliance, the plenum, and the duct above the cook line. When a fusible link melts or someone pulls the manual station, it discharges a potassium-based agent that saponifies burning grease into a smothering foam and simultaneously cuts gas and power to the appliances. Design and testing follow UL 300 and NFPA 17A, with semiannual service by a licensed technician tagged on the cylinder. Fire marshals and insurers both check that tag during inspections.
