Automatic Aerosol Fire Suppression System For Engine Room Fire
Protection
FireLess 2.0 Application for engine rooms of buses
The fire reasons of engine rooms
The engine room is one of most important component for a bus. But
the environment of engine room is complex and have many risks of
fires.
With the development of automotive technology, the total length of
electrical circuits used in various control devices and
transmission devices in the car has increased tenfold compared to
20 years ago, and many wiring harnesses are placed in the engine
compartment and the instrument panel. These harnesses run directly
through the entire body and are fixed by various clamps and then
inserted into a relatively narrow space, so they are often affected
by the heat, vibration and shaking of the running engine, although
they are protected by cushioning materials or protective covers.
The insulation layer is still very easy to damage. After the
insulation layer is damaged, it is easy to cause a short circuit.
Besides, electrical faults such as overcurrent and poor contact
caused by the electrical circuit or electrical equipment in the
vehicle are also important causes of vehicle fire.
- The failure of the oil circuit system
Mainly fires are caused by aging, cracking, falling off, burning,
etc. of the fuel pipe.
- A failure in the exhaust system caused a fire.
During the operation of the vehicle engine, the exhaust system
emits a large amount of heat, and the exhaust pipe and other
components are always in a high temperature state. Once the
combustible material comes into contact with it, it may cause a
fire.
Why choose FireLess 2.0?
FireLess 2.0 condensed aerosol fire extinguishing system is a
better choice to protect the engine rooms. Small volume and compact
design make it particularly suitable the narrow, complex and harsh
environment. The sealed shell can prevent any external dirties into
the fire extinguishing devices and can not affect its functions and
performances. Different starting methods make it more flexible and
accommodate to the different requirements of clients and customers.
And the most important thing is that to extinguish fire very
rapidly. FireLess 2.0 discharge time is at most 6s, so the fires
can be controlled and extinguished in few seconds. And the fire
extinguishing gas shall be filled with the whole space with 30
minutes. The flame can not burn up again.
Because fire extinguishing gas will disappear as time goes by.
There is no residual fire extinguishant left, so the equipment will
not damage the equipment in the second time and fire place is easy
to clean and protect the things utmost.
