POWDER EXTINGUISHING SYSTEM

Product Description

Dry powder fire systems

The extinguishing powders used in powder extinguishing systems are highly efficient, quick-acting extinguishants. The sudden extinguishing effect of the powder cloud is caused by the suffocation effect and the anticatalytic effect, a chemical intervention into the combustion process. Extinguishing powders mainly consist of non-poisonous inorganic salts mixed with waterproofing and pouring agents. They are used for fires with solid, liquid or gaseous substances and for metal fires, thus, they are used for fire classification A, B, C and D.

Large powder extinguishing systems
If several rooms and objects are to be protected with powder extinguishing systems, a central powder storage in compression-proof steel vessels, which is sufficient for all protection areas, should be provided.

Small powder extinguishing systems
Small powder extinguishing systems are recommended for objects with a limited scope of protection. To a great extent the design and dimensioning of such powder extinguishing systems is standardized for several similar objects and thus, costs are minimized. They are preferably used in extractor hoods, exhaust air ducts, laboratories and experimenting institutes etc.

Range of application:
e.g. chemical works, petrol dumps, compressor and pump stations, utilities substations for oil and gas, gas burner stations at boiler plants, oil cellars, rolling mills, test stands, hydraulic systems, aircraft hangars, LNG, LPG and chemical tankers, laboratory rooms and equipment, hazardous waste systems
