Kitchen Fire Suppression Systems for Commercial Catering

Commercial kitchens are high-risk environments where fires can escalate quickly if not dealt with immediately. With high temperatures, open flames, oils, and electrical appliances all in close proximity, the risk of ignition is significant.

At Astro Fire Systems, we install and maintain certified kitchen fire suppression systems built to respond rapidly and effectively, minimising risk to your business, your team, and your customers.

Built for the Foodservice Industry

Kitchen fires account for a notable percentage of non-residential fires and injuries. Common causes include:

  • Faulty or unattended cooking equipment
  • Overheating oil or grease build-up
  • Defective heating controls
  • Poor maintenance or cleanliness

Our KitchenGuard systems are engineered to automatically detect and suppress fires at the source, delivering unmatched safety and peace of mind. This solution is certified to LPCB LPS1223, a recognised standard for fixed fire suppression in commercial catering.

How KitchenGuard Works

KitchenGuard uses a pressurised linear detection tube installed discreetly in high-risk zones such as over hobs, fryers, ovens, extract canopies, and ductwork. When exposed to flame or heat, the tube bursts at the hottest point, releasing pressure and activating the system.

This opens the system’s valve, releasing a biodegradable wet chemical extinguishant through stainless steel pipework and nozzles, directly targeting cooking appliances and extraction ducts.

System features:

  • No electrical input required – functions during power cuts
  • Automatic or manual activation
  • Shutdown signal to isolate gas and electricity
  • Continuous protection, 24/7
  • Easy system health monitoring via pressure gauge

Designed for Real Kitchens

KitchenGuard is robustly engineered for the demanding kitchen environment:

  • Stainless steel pipework and fittings – durable and hygienic
  • Grease- and dirt-resistant detection tubing – reliable even in the toughest conditions
  • Non-invasive installation – quick and efficient, minimal downtime
  • Flexible layout – adapts to your kitchen setup and equipment

Whether you run a café, restaurant, hotel, or large-scale catering operation, KitchenGuard can be configured to meet your needs, offering both appliance-specific and zonal protection.

Environmentally Friendly Fire Protection

The KitchenGuard system uses a biodegradable wet chemical extinguishant, making it a safer and more environmentally responsible choice. It operates by saponification turning hot cooking oils into a soapy, non-flammable substance that cools and suppresses flames while preventing re-ignition.

This agent is non-toxic, non-corrosive, and can even be used as a cleaning aid for residue and grease.

Modular & Scalable Installation

KitchenGuard is available in pre-engineered modular kits:

  • 8-litre system: up to 4 nozzles
  • 12-litre system: up to 6 nozzles

Multiple modules can be linked together for larger kitchens. The modular design also supports future expansion, making system updates simple and cost-effective.
