Kitchen Fire Suppression System: Critical Protection for Commercial Kitchens 2025

Kitchen Fire Suppression System

In fast-paced commercial kitchens, where heat, oil, and open flames collide daily, a fire can ignite in just seconds. A kitchen fire suppression system is your first—and often only—line of defence against catastrophic damage, business disruption, or injury.

At Flexco, we’ve been supplying and sourcing parts for commercial kitchen fire systems for over 30 years. From fire contractors to facility managers and restaurant owners, clients across Australia rely on us for reliable, compliant components that ensure their systems stay ready 24/7.


🍳 What Is a Kitchen Fire Suppression System?

A kitchen fire suppression system is a pre-engineered fire protection setup designed to detect and suppress fires in commercial cooking environments automatically. It uses wet chemical agents to:

  • Quickly suppress flames
  • Cool hot surfaces
  • Form a vapour-sealing barrier over flammable liquids (like oils and grease)

The system typically covers:

  • Deep fryers
  • Grills
  • Cooktops
  • Range hoods
  • Exhaust ducts

When fire is detected—either via fusible links, heat sensors, or a manual pull station—the system instantly discharges the agent and shuts down fuel or electrical supply to prevent reignition.


🧩 Components of a Kitchen Fire Suppression System

At Flexco, we provide the essential components that make up a functional and compliant system:


✅ 1. Wet Chemical Agent Cylinder

The heart of the system. Stores and dispenses fire suppression liquid, typically potassium acetate, known for knocking down grease fires fast.


✅ 2. Detection System

  • Fusible Links: Heat-sensitive metal links that break at preset temperatures
  • Detection Cable: Mounted across hood areas and ducting to sense heat rise
  • Manual Pull Stations: Wall-mounted triggers for emergency manual discharge

✅ 3. Discharge Nozzles

Nozzles are strategically mounted over cooktops, fryers, and hoods. Flexco supplies various nozzle types based on system brand and appliance layout.


✅ 4. System Control Components

  • Actuation Mechanism
  • Release Module
  • Pressure Switch
  • Electrical Interlock to shut off gas or electricity to appliances

✅ 5. Pipework, Tubing, and Brackets

All hardware for installation and secure mounting of system components.


⚖️ Compliance Matters: AS3772 and AS1851

Kitchen fire suppression systems in Australia must meet strict fire codes, including:

  • AS3772 – Pre-engineered fire suppression systems for commercial kitchens
  • AS1851 – Routine servicing of fire protection systems

Systems must also be:

  • Installed by licensed professionals
  • Maintained at 6-month and annual intervals
  • Tested after activation or environmental wear

Flexco ensures all parts we supply are compliant with relevant Australian and international standards.


🛠️ Replacement Parts for System Servicing

Fire system servicing often requires component replacement. We help contractors and service teams source:

  • New fusible links and detection cables
  • Replacement nozzles
  • New agent cylinders (pre-filled or refill-ready)
  • Pressure gauges and valve seals
  • Actuators and system mounts

Don’t waste time chasing parts across suppliers. Flexco can build full replacement kits to match the system on-site—fast, accurate, and ready to install.


🔥 Why Fire Suppression in Kitchens Is Crucial

The kitchen is the most common origin point of fires in commercial premises. Without a suppression system, a grease or stovetop fire can:

  • Destroy cooking equipment and ventilation systems
  • Trigger smoke damage throughout the premises
  • Endanger staff and customers
  • Lead to closure, fines, or insurance breaches

A kitchen fire suppression system:

  • Responds instantly to high temperatures
  • Releases agent directly where fire is burning
  • Prevents reflash with chemical residue seal
  • Integrates with alarm and fuel shutoff systems

Installing or maintaining this system isn’t just smart—it’s often legally required.
