What Our Hood Systems Protect

A properly designed grease hood suppression system protects three critical areas:

Hood Plenum

Nozzles mounted in the hood canopy target grease accumulation and flames at the source

Exhaust Duct

Duct nozzles prevent fire from traveling through the ventilation system to the roof

Cooking Appliances

Individual nozzles over fryers, grills, woks, and other high-risk equipment

UL 300 Compliance Required

All commercial kitchen fire suppression systems in California must meet UL 300 standards. This modern standard requires wet chemical agents specifically designed to suppress high-temperature vegetable oil fires.
