Discover the Ansul R-102 Fire Suppression System
The Ansul R-102 Fire Suppression System is a pre-engineered wet-chemical solution designed to help protect commercial kitchens, restaurants, fast-food chains, and other food-service environments from cooking-related fire risks. Built for high-risk cooking surfaces, grease extraction equipment and kitchen appliances, this Ansul system supports dependable fire protection where safety, compliance and business continuity matter.
Why Choose the Ansul R-102 Fire Suppression System?
In high-temperature commercial kitchens, efficiency, compliance and fire safety are essential. The ANSUL R-102 Restaurant Fire Suppression System is an automatic, pre-engineered kitchen fire suppression system developed for demanding commercial spaces and widely used across the food service industry.
It is designed to detect and suppress fires quickly, helping reduce the risk of major damage when every second counts. For businesses where a fire emergency can happen without warning, a reliable suppression system is essential for protecting people, property and day-to-day operations.
Rapid Kitchen Fire Suppression
The Ansul R-102 uses ANSULEX Low pH Liquid Agent, a wet chemical agent designed for commercial kitchen fire suppression. This low pH extinguishing system helps attack burning fat and grease fires, knock down flames, cool hot cooking surfaces and create a vapour-securing blanket that assists in preventing re-ignition.
By targeting the hazard at the cooking surface, the system helps secure the atmosphere around the affected area and reduce the chance of a fire spreading through grease-laden vapours, extraction equipment or connected ducts.
Comprehensive Protection
Designed to protect vital cooking area hazards, the Ansul R-102 covers ducts, hoods, filters, plenums, auxiliary grease extraction equipment and cooking appliances such as fryers, range tops, griddles, broilers and woks.
For high-risk cooking environments, businesses should not rely on a portable fire extinguisher or portable extinguishers alone. A fixed suppression system should be selected through a proper fire risk assessment and aligned with fire safety, building and insurance requirements.
Two Protection Options
The Ansul R-102 offers two protection options: appliance-specific design and overlapping protection.
Appliance-specific coverage aims nozzles at the hazard areas of specific appliances, helping optimise agent use and reduce unnecessary storage tanks and hardware. Overlapping protection can create a continuous zone of coverage along a line of equipment, making it suitable for flexible kitchen applications where appliances may be rearranged.
During installation, nozzle selection, pipework and predetermined flow rate requirements must be matched to the approved system design.
Flexible Design for Ongoing Protection
The flexible design supports overlapping appliance protection, helping maintain coverage if equipment layouts change. Nozzles can be arranged in a straight line to provide broad coverage beneath the hood, while the overall system layout can support a smoother installation process and more straightforward long-term maintenance planning.
This makes the Ansul R-102 a practical solution for commercial kitchens that need reliable protection today, while also allowing for future changes in equipment, layout or kitchen applications.

Benefits of the Ansul R-102
Ansul fire suppression systems help minimise fire damage, protect your premises and reduce disruption to your staff and business. Automatic detection means the system does not rely only on an operator, while the wet chemical agent is typically localised to the protected cooking area, helping simplify clean-up when compared with wider water discharge from a sprinkler system.
For many commercial kitchens, a compliant and properly maintained suppression system can also support insurer expectations and may be treated as an insurance requirement. It provides a safer fixed fire protection solution than relying on fire extinguishers or fire blankets alone.
FAQ
What is an Ansul system?
An Ansul system is a specialist fire suppression system designed to protect high-risk environments. In commercial kitchens, the Ansul R-102 is used to help detect and suppress fires involving grease, burning fat, cooking surfaces, extraction systems and kitchen appliances.
How much does an Ansul system cost?
There is no fixed cost for every Ansul system, as each commercial kitchen needs to be surveyed and a system design carried out before an accurate quotation can be provided. The final cost will depend on the kitchen layout, cooking equipment, extraction system, level of coverage required and installation requirements. As a guide, for a typical-sized commercial kitchen, an Ansul system would usually be expected to cost between £3,000 and £5,000. LJM Fire Solutions can survey your premises and provide a clear quotation based on your specific fire suppression requirements.
Is the Ansul R-102 the same as Ansul R 102?
Ansul R-102 and Ansul R 102 usually refer to the same restaurant fire suppression system. The hyphenated version, Ansul R-102, is the standard product name.
Does an Ansul fire suppression system replace a fire extinguisher?
A fixed suppression system should not be seen as a simple replacement for every fire extinguisher. It provides automatic protection for specific kitchen hazards, while portable extinguishers may still form part of wider fire safety planning depending on the risk assessment and site requirements.
How often does an Ansul system need maintenance?
Maintenance should be carried out routinely by competent fire protection engineers in line with the approved system design, manufacturer guidance and relevant fire safety requirements. Regular maintenance helps ensure the system remains ready to operate in an emergency.
Can the system protect different kitchen appliances?
The Ansul R-102 can be designed for specific appliances or overlapping kitchen applications. It can protect equipment such as fryers, griddles, range tops, broilers, woks, hoods, ducts, filters and grease extraction areas.
