Fire safety manufacturer Jactone has introduced a kitchen fire suppression system called PAFSS KitchenGuard which uses a novel method to respond to fires.
Instead of the traditional mechanical actuation, KitchenGuard works through pressurised detection tubing which is installed in front of the filters under the hood, behind the plenum (space behind the filters) and into the duct.
In a fire situation the flame melts the pressurised tubing and a hole appears.
The drop in pressure in the tubing opens the valve on the system cylinder and the wet chemical extinguishant is delivered via a system of stainless steel pipework and nozzles onto the appliances, into the plenum and up into the duct.
Jactone believes that this linear method results in much faster fire detection and system activation, as the flexible detection tubing means there is an unlimited number of detection points.
The system valve activation takes place by pneumatic signal only, so no other mechanical movement or electrical operation should be required.
The manufacturer says that oil/grease/dirt contamination of the detection tube does not inhibit its operation.
Pressure vessels are manufactured in the UK by Jactone, so the company has complete production control.
The extinguishing medium is designed to be more than 99% biodegradable, while the manufacturer states the systems are simple and cost effective to install, commission, service and maintain.
Integral system pressure gauges should enable system health monitoring at a glance, and extra monitoring is available with pressure switches for both health (low pressure) and discharge confirmation.
Up to three modules can be connected pneumatically by a ‘PAFSS Pneumatic Link’, to act together as part of a larger system.
PAFSS KitchenGuard is certified and approved by LPCB to LPS1223.
