Introducing the P50 Composite Extinguisher

The Revolutionary Idea The P50 was developed from listening to the concerns of the customers, and the high cost of servicing. The aim is to use

new technology to remove extensive maintenance in products. It took five years to perfect a revolutionary fire extinguisher

which requires no servicing. The P50 doesn’t just address issues surrounding the cost of servicing and maintenance, but

also answers other needs including durability, resistance to damage, resilience to the elements, guaranteed long life-span

and addresses client’s environmental targets.

The P50 low maintenance extinguisher is the latest development in the worlds’ fire industry. These extinguishers are certified to EN3 and MED with a

20 year life, requiring no discharge replacement or refills for 10 years. The P50 is designed to remove corrosion and reduce maintenance because it only

requires a simple visual inspection by checking the gauges.

How is it inspected?

A simple in-house inspection is all that is needed – massively reducing your maintenance expenditure. There are two gauges, one to calibrate against the other giving a simple quarterly visual check on the working pressure. Annually the forward facing gauge can be checked for operational accuracy using a magnet to zero (on removal of the magnet the gauge will return to show the operational pressure). Inspection is just 3 easy steps – a visual inspection to check for damage, a check of the pressure gauges, and a check of the manufacturing date – it’s as easy as ABC.

How is it designed?Super strong aramid inner core-aramid is one of

the toughest composite materials known to man, used to create bullet proof vests and fire

retardant gloves. Britannia has used aramid to construct the inner core of the P50 extinguisher,

not only creating incredible strength and durability, but also preventing any form of

corrosion. One in 500 units manufactured is tested to destruction by pressurising the unit

12,000 times to 25 bar before crushing flat with a mangle. After this cycle the extinguisher is burst

to destruction at over 80 bar.

How is it designed?Dual pressure gauge are fitted on to the

P50 extinguisher. This allows cross-calibration of the pressure reading with a magnet. The magnet will move the needle to ensure it is not stuck and that the gauge

is fully functional.

HDPE outer body- The shell protects the P50 extinguisher’s aramid core which has been rigorously tested to ensure that it

provides durability in even the most hostile environments and has passed a

very vigorous fire resistance test.

How well does it perform?The P50 extinguisher is approved under EN3 with additional

testing to the composite gas cylinder regulations. Under these gas cylinder regulations a 12,000 cycle test on one in

500 is required. All P50’s are tested to 25 bar in production.In the EN3 burst test all extinguishers have to pass a

minimum 55 bar pressure testing, however P50 extinguishers have a burst pressure consistently reaching in excess of 80

bar.

P50 fire extinguishers incorporate two patented elements – the loose weave and the locking neck ring. This innovative

design provides ultimate protection with the added features of being lightweight and extremely durable.

Test Rig

Testing of the P50Testing of the P50 foam and powder extinguishers was carried out at a

purpose built fire test ground witnessed by the European inspection authority Apragaz.

The 6ltr foam has a fire rating of 27A / 183BThe 6kg Powder has a fire rating of 34A / 183B

Why is this so unique?

We have used design technology first pioneered by motor racing, defence, aircraft and aerospace

industries. It uses an extremely tough, yet light fibre material from the aramid family known by the

name Kevlar. Kevlar is so tough it is used as the primary composite material in bullet proof vests

and fire proof gloves! It is the first time composite materials have been applied to the design of fire

extinguishers.

This product will eliminate untold mileage in engineer service and maintenance visits – and therefore will massively reduce a large corporation’s carbon footprint and help them to achieve yearly environmental targets.The product is 100% recyclable. At the end of its life, Assured can provide a replacement programme. The manufacturing process of the P50 extinguishers is state of the art and environmentally clean requiring little energy. Unlike metal extinguishers it requires no welding, no degreasing, no shot blasting, no painting and no manufacturing waste disposal.With a 10 year guarantee on each P50 extinguisher, the necessity for regular discharge test (environmentally unfriendly) and replacement of extinguishers will be gone, saving on transport costs and carbon footprint.All metallic extinguishers require discharging to enable internal corrosion inspection every five years, also to ensure internal polythene linings are not separated – which is a common area of failing. The inspection requires the fire fighting chemicals to be discharged, (in most cases for companies the simply way is to replace the extinguisher) however most chemicals are not reused and end up in landfill sites. The P50 extinguishers have no internal polythene lining and also do not corrode – internally nor externally – therefore this risk is eradicated and so too is the need for internal inspection, associated inspection costs, chemical waste and pollution.
