The Problem

There are many situations where assets and property are under threat from the risk of fire, either because of the unattended nature of their operations or simply their remote location. Unattended risks can be present in for example: laboratory fume cupboards, automatic machinery, engines and offshore wind turbines (which are characterised by their remote locations).

All of these applications, along with many others, are a challenge due to the fact that human intervention in the event of a real fire situation is highly unlikely or just not possible. In addition to this the fire could be difficult to identity, for example smouldering, damaged to poorly installed wiring inside an electrical cabinet which could present a real problem.

The unattended nature of these operations means that if a fire has to develop it would be very likely that by the time external flame, heat or smoke detecting devices became aware of the situation the fire may have spread to surrounding equipment and assets.

The PAFSS Solution

PAFSS fire suppression systems require no power for detection or to operate making them ideal for unmanned or unsupervised applications. PAFSS detection tubing is installed throughout and very close the risk areas in the protected application, providing fast and effective detection. Upon flame impingement or high ambient temperature the pressurised detection tube ruptures with a burst at the hottest point. Depending on the system type, the pre-selected extinguishing agent is then discharged from the connected cylinder through either the burst hole directly at the heart of the fire or via separate pipework and nozzles.

The simplicity of PAFSS systems and the nature of the linear pressurised detection tubing means that it is possible to protect some very challenging applications with a fire suppression solution. The detection tubing is very flexible which means it can be installed in tight spaces such as electrical panels, harsh environments such as engine compartments and recycling machines with relative ease.
Dealing with the fire situation at source in this manner means that the fire is extinguished extremely quickly and prevents the fire from spreading to neighbouring enclosures, equipment and the wider building, significantly reducing the risk of injury to personnel and losses caused by equipment down time and operational disruption.
