What is an aerosol fire extinguisher?

It is a compact, self-contained unit that releases an aerosol suppressing agent into a confined space to interrupt a fire without wet or powder systems.

How is it triggered?

Units can be released by heat-activated thermal elements or by a motor-driven or signal-triggered initiation, depending on the model and wiring.

Where is it used?

It is used in electrical enclosures, battery cabinets, distribution boards, and equipment housings where fire suppression must fit a small space.

Why choose aerosol instead of piping?

An aerosol unit needs no tanks, pipes, or large footprints, so it installs inside the enclosure with minimal planning.

How is the unit sized?

The unit is selected by the protected volume and the expected fire risk, matched to the enclosure dimensions and contents.
