Commercial kitchens have a fire risk that general-purpose suppression systems weren't built for — grease fires ignite fast, burn hot, and reflash easily if they're not fully knocked down at the source. Kitchen hood fire suppression is engineered specifically for that risk, targeting the cooking line, hood, and duct system as one integrated unit rather than treating the kitchen like any other room.What makes a grease fire different from most fires is that the fuel is already hot and liquid before ignition even happens — a fryer running at cooking temperature is close to its ignition point constantly, which is why a fire can start almost instantly and spread up through the extraction hood and duct if it isn't stopped right where it starts. A general sprinkler or clean agent system either wouldn't reach the fire fast enough or wouldn't counteract burning oil correctly, which is exactly why kitchen hood suppression exists as its own dedicated system category rather than a variation on standard fire suppression.We supply, install, and maintain kitchen hood fire suppression systems across Abu Dhabi, Dubai, Sharjah, and Al Ain, including Ansul system installations and other recognized wet chemical fire suppression system brands, sized to the specific cooking equipment and hood layout of each kitchen. Every fryer, grill, range, and griddle needs its own nozzle coverage calculated against its position and heat output, so a system designed for one kitchen's layout genuinely doesn't transfer as-is to a different one — we design around the actual cooking line, not a generic kitchen template.
Every kitchen hood fire suppression project starts with a site visit to map the actual cooking line — appliance types, positions, heat output, and the existing hood and duct layout — before anything gets specified. From that assessment, we design the nozzle coverage, agent quantity, and detection points needed to protect that specific kitchen, then supply the system components from recognized manufacturers, including Ansul and other established wet chemical suppression brands.Installation covers the full system: detection links or heat sensors mounted above each cooking appliance, the wet chemical cylinder and piping, nozzles positioned precisely over fryers, grills, and cooking surfaces, and the mechanical or electrical interlock that shuts off gas or power to the cooking line the moment the system triggers. We test the complete system before handover, confirming discharge coverage and the gas/electrical shut-off function actually work together, not just independently.We handle design, supply, and installation as one service rather than three separate handoffs, so the system that gets installed is the one that was actually designed for that kitchen, with no gap between the drawing and what's fitted on site.
A kitchen fire suppression system uses detection devices — usually fusible links or a linear heat detector — mounted above the cooking appliances, connected to a cylinder of wet chemical agent. When heat crosses the trigger threshold, the system automatically discharges the agent through nozzles positioned over the fryers, grills, and cooking surfaces, and simultaneously shuts off the gas or electrical supply to the cooking line so the fuel source is cut at the same moment the fire's being suppressed.
The wet chemical fire suppression system used in commercial kitchens is specifically formulated for grease and cooking oil fires — it works by cooling the fire and forming a soap-like barrier (saponification) over the burning oil, which smothers the fire and prevents it from reigniting. This is fundamentally different from clean agent systems like FM200 or Novec 1230, since kitchen fires need an agent that specifically counters burning grease, not just displaces oxygen or absorbs heat.
Ansul is one of the most widely recognized kitchen hood fire suppression system brands, and it's what many facility managers and consultants specifically ask for by name. We supply and install Ansul system components alongside other recognized wet chemical suppression brands, matching the manufacturer and configuration to what the kitchen's design or civil defence approval calls for.
We deliver certified Fire and security systems tailored to your facility’s needs.
