Ansul Fire Suppression
Artius FP® through our associated company are specialists in the supply, installation and maintenance of Ansul R-102 fire suppression systems.
Commercial kitchen fires are highly destructive. The potential loss to both property and life can be disastrous.
Conventional means of tackling kitchen fires include portable extinguishers and fire blankets.
Both these methods require:
Operatives to be present – Someone has to physically be in the kitchen to apply the fire blanket or discharge the fire extinguisher. If the fire breaks out in a period of down time or when the kitchen is closed, fire can rapidly take hold if not tackled.
Operatives to be trained – To avoid injury and to attempt to extinguish the fire, operatives need to be trained on the correct selection and correct use of various types of portable fire extinguishers.
Operatives to put themselves at risk – Operatives will physically need to approach fires to tackle them. In the case of the fire blanket, the operative will need to be directly above cooking appliances that are in flame. Without the correct protective clothing this is highly dangerous.
Kitchen Fire Suppression Systems (Ansul Systems)
Offer a robust solution to this problem. Ansul Fire Suppression systems consist of a liquid wet chemical agent stored in stainless steel tanks and enclosures mounted adjacent to the kitchen extract canopy.
Fixed pipe work extends from the tanks into the extraction plenum areas and above the risk cooking appliances. Specific discharge nozzles are installed above each hazard appliance, behind the grease filters and up into the extract ductwork.
How it works
When a fire occurs in a protected area, it is quickly detected by the sensors in the cooker appliance hood. The detectors trigger the Ansul Automan releasing mechanism which actuates the system – pressuring the agent storage tank and automatically shutting off the appliance energy.
The low pH liquid fire suppressant flows through the piping and is discharged into the plenum and duct areas and onto the cooking appliances. The ANSULEX agent is applied directly onto the fire in spray patterns, suppressing the fire in seconds. It smothers the hot cooking greases, a foam blanket is formed, temporarily sealing off combustible vapours to help prevent fire re-flashes.
The system’s exclusive stainless-steel enclosure is completely self-contained – so blending in beautifully without affecting the kitchen’s operation.
Did you know?
If your kitchen uses commercial deep fat frying equipment, then a fixed fire suppression system is essential. Any cooking area over 0.4sqm requires a fixed suppression system rather than a portable liquid fire extinguisher. This is because a portable liquid fire extinguisher can cover up to 0.4sqm area, but above that, it is recommended to avoid multiple small extinguishers. They may not do the job of extinguishment, so a fixed suppression system is the solution. Fire blankets, dry powder, wet chemical or CO2 extinguishers cannot extinguish burning fat in any significant quantity.
Amerex Fire suppression
Amerex offers the widest choice of approved kitchen fire suppression in the market place with detection and suppression options to suit every scenario. The systems are listed by Underwriter’s laboratories, Inc., (UL) and tested to standard UL300 and approved by LPCB (LPS1223). Their pre-engineered wet chemical fire suppression systems were designed for protection of kitchen hoods and ducts, and the cooking surfaces of appliance hazards. The Amerex fire suppression systems use less wet chemical agent thanks to an overlapping spray design (an innovation that they pioneered). With Amerex, the agent is in a nearby tank. Everything is self-contained for lower maintenance costs.
How it works
Amerex uses tried and tested technology to quickly detect a fire. It can also simultaneously interface with any gas valve/electrical supply to the equipment the fire is detected on.
The Amerex suppression agent is then discharged onto the fire, forming a solid layer of foam. This instantly cuts off the oxygen supply to the fire, suppressing it and cooling it. After an activation, the system can be recharged on-site by one of our technicians, ensuring that your kitchen is safe to use again the same day.
Amerex offers two systems to meet the industry’s varying needs:
KP Restaurant Fire Suppression System
Appliance-specific coverage that typically offers lower initial cost.
The KP system is ideal for uses where appliance location is fixed, such as in fast food chains, casual dining, cruise ships and school cafeterias.
The KP System uses individual “Dedicated Appliance Protection” for each appliance under the hood requiring protection. A choice of the fire detection method may be a standard thermal link network or one of the two linear detection networks. (PRM or Linear Fusible Link).
ZD Restaurant Fire Suppression System
Designed with fine dining, culinary schools, military facilities, hotels and hospitals in mind.
Zone Defense System was developed for the kitchen that changes out its cooking appliances frequently to accommodate the change in menu or cooks.
The ZD System provides a detection system and protection system which allows for the moving and rearranging of appliances without changing the fire suppression piping or detection device locations. This is accomplished by using a detection network that will detect a fire no matter where it occurs under the hood, and will extinguish cooking appliances located anywhere under the hood, as long as they are inside the “Zone of Protection”.
