Extinguishing aerosol generators are modern devices used to extinguish A, B, C and F class fires. They are primarily used in confined rooms, where it is impossible to install a water system. The following information explains how extinguishing aerosol generators are built and how they work.
Traditional extinguishing measures follow the principle of reducing temperature, and isolating or lowering the supply of oxygen required for the combustion process. The principle of operation of extinguishing aerosol generators involves breaking the combustion reaction chain by binding free radicals with a special extinguishing aerosol formed through solid material transformation. This leads to complete flame elimination. Normal oxygen level is preserved in the air. This method generates a minimum volume of contaminations.
Extinguishing aerosol generators take the form of cylinder-shaped containers made of acid-resistant steel. They are very durable and their operating temperature range is from -45 to +70oC. There are both portable and permanently mounted versions available on the market. Their installation is quick and simple, and does not require reconstructing rooms. However, the installation must be conducted by qualified specialists. A trigger, such as a fire alarm button and a power supply, USP autonomous temperature sensor, and a thermal wire at a temperature above 172oC are required to trigger the generator.
Where will extinguishing aerosol generators work?
High effectiveness of the generators was confirmed in relation to A, B, C and F fires, as well as fires of 36 kV electrical devices. Extinguishing aerosol generators are a great choice for large and hard-to-reach rooms, such as production halls, warehouses, server rooms, machine rooms, boiler rooms, archives, technical rooms and others. They can constitute independent devices or be part of a fire protection system. They are safe, effective and independent from an external power source.
