Kitchen Suppression Systems

The installation of kitchen fire suppression systems is being specified more and more by insurance companies as they recognise that industrial kitchens are a major source of fires within premises. Flammable liquids, gases, food, oil and ignition sources are a major concern for insurance companies and are major risks of a fire starting in kitchens.

Kitchen fires have generically been tackled and attempted to be extinguished by kitchen staff using fire extinguishers and fire blankets, both these methods of fighting fire require operatives to be present and specifically trained, they also put themselves at risk. Crucially, portable fire extinguishers and fire blankets cannot tackle flames that may have spread into kitchen canopies and extract ducts. Once fire spreads into extract systems a surface coating of grease can quickly spread fire throughout a building.

Kitchen fire suppression systems can operate automatically or manually, either method of actuation will interrupt gas or electrical power to the appliances prior to system discharge. The extinguishing media is fed through fixed pipe work installed from the tanks/enclosures into the cooking hood through discharge nozzles over appliances, behind grease filters and up into the extract ductwork.

Systems are designed specifically for each kitchen regardless of size and layout. Each design can provide overlapping protection known as zone defence (ZD) Fig 1 or appliance specific such as, deep fat fryers, bratt pans, salamanders, grills etc known as (KP) Fig 2.

What does Ansul do?

Ansul offers a few different types of extinguishing systems, the most common in the UK is the R-102 Restaurant Fire Suppression System. 

Overlapping Appliance Protection is one of the two design options available with the R-102 Restaurant Fire Suppression System. The design is flexible and simple. Nozzles are installed in a straight line with a maximum nozzle spacing of 25.5 in. (647 mm) and a height of 40-45 in. (1016-1143 mm) above the cooking surface. The nozzles are not aimed individually at specific appliances but instead are aimed at the hazard zone centerlines. These overlapping discharge patterns create a continuous zone of protection in which all appliances within this area are protected.

The R-102 system discharges ANSULEX Liquid Fire Suppressant, which quickly knocks down flames and cools hot surfaces, while generating a tough vapor securing blanket that helps prevent reflash

The R-102 system is designed to protect areas associated with ventilating equipment, including hoods, ducts, plenums, and filters. It also protects auxiliary grease extraction equipment and cooking equipment such as various types of fryers, griddles, range tops, broilers, char-broilers, and woks.

The R-102 system is ideally suited for commercial kitchens in fast food chains, retail food courts, restaurants, catering facilities, mobile food vehicles, hotels and casinos, stadiums, schools, nursing & care homes, hospitals, and more.
