PAFSS FUME CUPBOARD FIRE SUPPRESSION
Laboratory fume cupboards, also known as fumehoods and fume cabinets, can present a particular problem where multiple users and a wide range of chemicals and processes increase the risk of fire. Our range of PAFSS Fume Cupboard Fire Suppression Systems can offer you the protection required.
These self contained pneumatic systems require no external energy or power supply. Upon flame impingement or heat, the pressurised detection tubing will burst and activate the cylinder valve to open and release the extinguishing agent.
The Jactone PAFSS Fume Cupboard Fire Suppression Systems have been specifically designed to protect laboratory equipment and is manufactured under the ISO 9001 quality system.
PAFSS Fume Cupboard Fire Suppression Systems are fitted at several prestigious institutions and laboratory sites.
On guard 24 hours a day, 365 days a year
Fume cupboards are installed in most laboratories where there is often multiple users, a wide range of chemicals and different processes that can considerably increase the risk of a fire.
Due to the semi-enclosed nature of fume cupboards, fires can be difficult to identify, which often means that it is too late for users to take action as the fire will have developed. Typically fume cupboards are found in multiple numbers in close proximity which means that a fire that originates in a single piece of equipment can spread to other adjacent equipment.
The results can be devastating, resulting in the risk of lost research, costs, downtime and danger to staff or students.
THE PAFSS SOLUTION
Fume cupboards require a specialist fire suppression system that is capable of detecting and extinguishing a fire situation within the fume cupboard workspace, dealing with the fire event locally before it can more fully develop.
PAFSS systems are specifically designed to detect and discharge inside the fume cupboard at the heart of the fire, extinguishing quickly and preventing any spread or escalation of the fire to neighbouring fume cupboards and the wider building. This can significantly reduce the risk of injury to personnel and losses caused by equipment down time and operational disruption.
These fire suppression systems offer peace of mind for customers looking to protect their assets and staff from the risk of fire.
HOW PAFSS WORKS
PAFSS fire suppression systems are self-activiting and require no external power for detection or operation making them ideal for unmanned or unsupervised applications.
PRINCIPLES OF OPERATION
At the heart of any PAFSS system is the special detection tubing which acts as a linear heat and flame detector. PAFSS detection tubing is completely flexible and is installed throughout the risk areas of the enclosure, providing fast and effective detection.
Upon flame impingement or high ambient temperature, the pressurised detection tube ruptures with a burst at the hottest point and by depressurisation the cylinder valve is activated. The extinguishing agent is then discharged from the connected cylinder through either the burst hole (Direct) or pipework (Indirect) at the heart of the fire.
Choosing PAFSS fire suppression systems has many advantages including:
• Simple to install and cost effective to maintain.
• Fast, automatic detection and extinguishing.
• Linear detection tube giving increased responsiveness.
• Detection tube is located where the fire risks are.
• Detection tube is unaffected by dirt, dust, debris and oil.
• Operated by pneumatic signal.
• Requires no associated mechanical operation.
• No external electrical power supply required.
• Remain operational during a power interruption.
• Stainless steel discharge pipework and nozzles.
• Reliable, vibration resistant push-fit detection tube fittings.
• Superbly engineered specialist valves and pressure vessels.
PAFSS SYSTEM SELECTION
PAFSS is available in two different arrangements, direct systems and indirect systems.
Direct systems both detect and discharge via the PAFSS detection tubing.
Indirect systems detect fire via the detection tubing but discharge via stainless pipework and nozzles.
