Armstrong Priestley are a world class provider of fire suppression systems, offering full turnkey solutions for all critical environments
At Armstrong Priestley, we offer our fire suppression systems where conventional automatic sprinklers won’t suffice.
The ultimate goals of this solution is to protect life, property and highly valuable assets; whilst also ensuring the continuity of key business activities, massively limiting downtime and enabling maximum output.
Inert Gases
Armstrong Priestley’s inert gas fire suppression systems, such as IG55 or IG541, are colourless, odourless, non-corrosive, electrically non-conductive blends and are safe for life within occupied spaces, with a density approximately the same as that of air. Excellent visibility is maintained during discharge, allowing efficient evacuation of the risk. Composed of naturally occurring gases, these inert gasses have no negative effects on the ozone layer or global warming. Safe and very effective for any protected area.
Chemical Gases
Armstrong Priestley’s chemical gas fire suppression systems, such as NOVEC 1230 are environmentally friendly, odourless, colourless, non-conductive, do not produce residue and are safe for life within occupied spaces. The main advantage of chemical gas is the small amount of agent required to suppress a fire. Fewer cylinders are required resulting in one of the smallest footprints compared to most other fire suppressants. No residue is produced, avoiding costly clean up. These gases do not deplete stratospheric ozone, have minimal impact on the environment and also have an extremely low global warming potential (ODP)
Co2
Carbon Dioxide has been utilised in a wide variety of applications to fight fires. It is generally used in areas that are designated as “un-occupied”, as at the design concentrations used for fire suppression carbon dioxide can be hazardous to people. It has the advantage over other extinguishing gases that in can be used as a “total flood” to protect areas such as generator rooms, switch rooms. Also it can be also used as “local application” where it can be discharged directly on to a high risk area of a production line such as a printing press, deep fat fryer’s.
Carbon Dioxide produces no chemical residues or decom-position products, therefore making it ideal to use in the food industry and industries where contamination of a process or product is not an option.
Watermist
Armstrong Priestley’s water mist systems optimise the quantity of water used through the distribution of very small droplets, achieving maximum cooling effect. Spray heads discharge water mist at high pressure. The tiny drops create a large effective cooling surface area and the high speed of the droplets allows the mist to penetrate hot fumes and reach the combustion area. Once in contact with hot bodies and gases the droplets become a vapour, absorbing the heat and creating a smothering effect that protects any adjoining risks.
Aerosol Systems
Armstrong Priestley also offer Aerosol based Fire Suppression systems that contain the latest generation of FPC Compound, consisting mostly of Potassium salts with non-pyrotechnic materials. When activated, the FPC converts into a fast expanding, highly efficient and effective fire suppression condensed aerosol that is distributed evenly in the protected enclosure, using the momentum developed in the transformation process.
In comparison to the traditional fire extinguishing methods (gaseous or fire sprinkler systems), the fire is extinguished predominately by intruding the chemical chain reactions in the flame as per the tetrahedron of fire, without draining oxygen. Additionally, FirePro is compatible with conventional and addressable fire alarm systems.

We are dedicated to delivering quality every time and this is reflected in our track record and commitment to Third Party Certification. Armstrong Priestley maintains LPCB Level 4 Certification for commercial and industrial fire sprinkler systems and FIRAS Certification for Residential and Domestic fire sprinkler systems. This allows us to certificate all of our work whatever the size or complexity of the project and ensures that our clients only receive the best advice and compliant systems every time.
The ISO 9001:2015 certification covers our Leeds office only. However, our Maidstone, South Shields and Manchester offices all operate in accordance with the same Quality Management System.
