Buses Engine Room Aerosol Fire Extinguishing Generators Fighting
Fires
Basis information of FireLess 35 Aerosol Fire Extinguishing
Generators
The automatic condensed aerosol fire extinguishing generator
FireLess 35 with circular nozzles discharges the aerosol flow by
electric start. Because of good compatibility, it can connect with
present alarm and security systems in the market. It also has other
impressive advantages: Small but beautiful. It has small size and
volume, only 0.01cubic meters product volume, but it can protect 35
cubic meters. Very cost efficient, FireLess 35 do not need any
costly spare part and pipes to transport the gases. Very easy and
simple to install and use.

Application of FireLess 35 in the bus engine room
The importance of buses engine room fire protection
With the increasing use of passenger buses, fire accidents have
become more frequent due to intentional arson, mechanical failures
and electrical faults. A major safety accident caused by a fire in
a passenger bus is likely to cause great harm to the society and
people's lives and property, and it also brings potential mental
fear to the people's psychology. Therefore, it is extremely
important to analyze the cause of fire and conduct early warning
and fire suppression system.
The causes of bus fires
To analyze the cause of the fire, mainly from the source of fire
and combustibles. Through the experience of many passenger bus fire
accidents in recent years, it is found that the passenger bus
engine compartment is the hardest hit area of the passenger car
fire, accounting for more than half of the total passenger car fire
accidents. The common causes of fires in the engine compartment of
passenger buses are as follows:
1.Line short circuit fire
Various types of sensor harnesses, controller harnesses, taillight
harnesses, air conditioning harnesses, starters and generator
harnesses are placed in the engine compartment, which may cause
short-circuit faults due to high temperature aging, damage,
accidental impact or maintenance errors. The thermal effect of the
short-circuit current causes the temperature of the wire harness to
rise sharply, causing the insulating layer to melt and burn and
ignite nearby combustibles.
2.Except for line short- circuit problems, engine exhaust system
leakage, fuel leak, engine oil leak and intentional man-made
destruction or mistaken operation and maintenance are also the main
reasons to lead an fires.
While FireLess 35 can be connected the alarming system with the bus
control terminal and its good adaptability make it very fit the
complex engine compartment environment and offer a accurate fire
suppression system to protect bus and the lives on it.
