What is Ansul® kitchen fire suppression?

An Ansul kitchen fire suppression system is a vital safeguard for any commercial kitchen, automatically detecting and extinguishing fires within seconds. Using a specialist wet chemical, it knocks down flames, cools hot surfaces, and creates a film that helps prevent re-ignition, protecting people, equipment, and business continuity.

Designed for real kitchen risks, the Ansul R-102 targets fryers, ranges, griddles, charbroilers, and the extract canopy and ductwork. It can trigger automatically via heat detection or be activated manually, then shut off gas and electrical supplies and raise an alarm for a controlled response. Many insurers expect certified suppression on higher-risk cooklines, so installing and maintaining an R-102 demonstrates due diligence alongside staff training and routine checks.

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for Ansul® kitchen fire suppression.

Trusted experience

With over ten years of experience designing, supplying, and maintaining Ansul systems, our team delivers reliable fire protection for kitchens of every size. As authorised Ansul distributors, we provide professional installation and servicing to keep your system fully compliant and ready to respond.

Accredited quality

We are proud to be the first company in the UK to achieve BAFE SP206 third-party accreditation for Ansul Kitchen Fire Suppression System provision. This certification demonstrates our commitment to industry excellence, ensuring all systems are installed and maintained to the highest standard.

Tailored protection

Each Ansul R-102 system is designed around your specific kitchen layout and appliances. Whether you need appliance-specific coverage or overlapping protection, we ensure precise, effective suppression. The system can also be activated manually via a pull station that integrates with your fire alarm for a coordinated evacuation.

Maintenance and compliance

Regular servicing is essential for performance and compliance. Our qualified engineers carry out six-monthly inspections, ensuring every nozzle, valve, and connection functions correctly. Routine checks also help maintain insurance validity and compliance with LPS1223 and UL300 standards.

24-hour protection and easy recovery

The Ansul system operates continuously, protecting your kitchen even when the premises are unmanned. Its Ansulex suppressant agent is non-corrosive and easy to clean, helping you return to normal operation quickly after an incident. This reduces downtime and limits fire-related damage.

Adaptable system design

The Ansul R-102 system can be configured in two ways. Appliance-specific protection targets only the high-risk areas, such as fryers or grills, while overlapping protection covers multiple appliances within a defined zone, allowing flexibility if equipment is relocated.
