Kitchen Hood Fire Suppression System Installation in Mesa, AZ | Fire Safety Systems
Mesa Hood & Exhaust Co. handles kitchen hood fire suppression system installation projects in Mesa, AZ for restaurants, hotels, school cafeterias, and food trucks. Our crews spend every working week inside Mesa hoods, so they see how grease coats nozzles and how a bumped pipe throws off coverage. That experience, built over 20 years, guides where each nozzle goes and how the piping runs.
A wet chemical system covers the appliances, the plenum, and the duct collar, and it connects to the gas shutoff and a manual pull station. When heat melts a fusible link, the agent discharges and the fuel stops flowing.
Every installation follows NFPA 17A, NFPA 96, and the manufacturer's manual. Our technicians photograph each nozzle and test the shutoff before inspection day, so Mesa Fire and Medical Department inspectors receive a full record. Kitchens in Gilbert and Chandler hire us for the same reason, since a system installed by the people who also clean the hood stays accessible for years.

Commercial kitchen fire suppression installation puts automatic fire protection over every cooking appliance, which hotels, school cafeterias, and hospital kitchens need before they pass a fire inspection.
Our licensed technicians map nozzles to each fryer, griddle, and range, then run stainless piping to an agent tank and connect the fusible links, manual pull station, and gas shutoff. When heat melts a link, the system floods the appliance and cuts the fuel supply, which gives your staff time to get out.


Restaurant hood fire suppression installation usually happens during build-out, after the hood hangs and before the fire marshal walks the kitchen.
Mesa Hood & Exhaust Co. coordinates with your general contractor so piping goes in before the ceiling closes, and the crew labels every nozzle position for the later inspection. The timing protects your opening date, since piping behind finished walls costs far more to move.
Type I hood fire suppression installation protects three zones at once, the appliance surface, the hood plenum, and the duct collar, because grease fires climb the exhaust path.
Our experts place appliance nozzles at the heights listed in the manufacturer's manual, then add plenum and duct nozzles that cover the filter bank and the duct entry. Full-zone coverage stops a fire where it starts instead of letting it reach the ductwork.


Wet chemical fire suppression installation suits kitchens that cook with vegetable oils and animal fats, since the liquid agent reacts with hot grease to form a soap-like foam that smothers flames.
Our technicians fill the tank to its rated capacity, pressurize it with nitrogen, and test each nozzle path. The foam also cools the oil and seals its surface, so a flare-up does not reignite after the burners shut off.
UL 300 fire suppression installation uses systems tested against the fast-heating fryers and high-efficiency cooking oils found in kitchens today, which older dry chemical designs struggled to put out.
Our crew matches every nozzle, pipe length, and tank size to the listed design, since the UL 300 listing holds only when the layout follows the tested limits. Inspectors and insurers then see the listing they ask for.


Fire suppression retrofit installation updates older kitchens whose original system no longer matches the equipment under the hood, a common gap after a fryer upgrade.
Our crew strips out the old tank and piping, installs a UL 300 wet chemical system sized to the new line, and tests the gas shutoff before leaving. Your existing hood and ductwork stay in place, so the upgrade costs less than a full replacement.
Our technicians list every appliance and note its size and height. That list sets the nozzle count and tank size.
Crews follow the manufacturer's manual to place appliance, plenum, and duct nozzles, then draw the pipe route and permit sheet.
Step 3: Run the Piping
Listed pipe and sealed fittings go in, and each nozzle aims at its zone using the manual's height chart.
Fusible links, the manual pull station, and the gas shutoff tie into the tank. Our experts then load the wet chemical agent.
Crews test link release, gas shutoff, and nozzle flow, then tag the tank and photograph each nozzle for your inspector.
Hood length and appliance count set the price, since every fryer, griddle, and range needs its own nozzles and larger lines need more tanks. Data from CostHack's 2023 rate guide lists typical installed systems at a range of $2,500 to $11,391 with an average near $4,979 and a low-end estimate of $3,819.
