Fire Detecting Tube and Aerosol, Which is a Better System?

There are many similarities between the application areas of fire detecting tube systems and aerosol systems, and their main application areas are power distribution cabinets and automotive engine compartments.

assim, which is the better system? We need to compare them in terms of application, instalação, agente extintor, and fire suppression efficiency.

Comparison of Fire-detecting Tube Systems and Aerosols in Applications

Fire detection tubes are mainly used in the following places:

• Cabine elétrica (Switchboards) and other control cabinets.
• Compartimentos do motor do veículo.

Em vez de, Aerosol systems are mainly for the following places:

• Cabine elétrica (Switchboards) and other control cabinets.
• Compartimentos do motor do veículo.
• Turbinas eólicas.
• Lithium battery packs, lithium battery cabinets, e recipientes de armazenamento de energia, etc.

Aerosols will be more widely used than fire tubes.

Comparison of Fire Detector Tube Extinguishing Systems and Aerosols in Installation

There are two types of fire detection tube fire extinguishing systems: fire detection tube systems with cylinders and fire detection tube units without cylinders.

We call them “cylinder-type fire detecting tube system” e “non-cylinder-type fire detection tube device”.

The cylinder-type fire detection system can be installed in an electrical cabinet, and each system can cover more than one cabinet by placing the red fire detection tube inside the cabinets, but it cannot normally be installed in vehicles. Em vez de, the non-cylinder-type fire detection tube device is good for vehicles, each vehicle will require 1 piece of non-cylinder-style fire detection tube.

Depending on the size of the space, aerosol fire extinguishing systems are generally:

• One set of aerosol extinguishers for one electrical cabinet(quadro de distribuição).
• One set of aerosol generators for one vehicle engine compartment.

Além disso, the installations of both aerosols and fire detection tubes require wiring and drilling.

Assim sendo, in terms of installation, their advantages and disadvantages are equal.

Comparison of Extinguishing Agents

The extinguishing agents of aerosols are mainly chemical mixtures, and the main substances that play a role in extinguishing fires are strontium nitrate and potassium nitrate. Aerosol fire extinguishing agents leave a small residue after spraying, but they are clean and do not damage electrical equipment.

While the main extinguishing agents for fire detection tube systems are NOVEC1230 or Heptafluoropropane, which are usually in liquid form and are gaseous when sprayed.
They are also clean and will not damage electrical equipment.

In terms of extinguishing agent comparisons, they are both clean extinguishing agents, and both have no adverse effects on electrical equipment or precision instruments.

Comparison of Fire Extinguishing Efficiency

The fire detection tubes are filled with NOVE1230(FK5-1-12) or HFC-227ea, and are designed for a density range from 600G/M3 to 720g/M3.

And the design density of aerosol is 100G/M3 TO 140g/M3. Contudo, Russian aerosol manufacturers have designed densities of 50g/m3 to 80g/m3.

From the above design of the extinguishing agent concentration, we can see that the extinguishing efficiency of aerosols is much higher than that of the fire detection tube.

além disso, aerosol fire extinguishing agents are highly concentrated agents, and it is clear that aerosol fire extinguishing agents are more efficient than the fire detection tube type.

What they both have in common is that they are total flooding to suppress fire.

Comparison of Extinguishing Agent Spraying Time

Fire detection tubes have a release time of less than ten seconds, while aerosols have a release time of between 0 e 60 segundos. Fire detection tubes have a shorter release time than aerosols.

It is the charge pressure that affects the discharge rate of the probe tube, while it is the burning rate of the extinguishing agent that affects the discharge rate of the aerosol.

Comparison of Packaging Methods

Fire detection tubes with carbon steel cylinders require special packaging materials, basically a fumigation wooden case.

Aerosols and fire detection tubes without bottles only require a normal 7-ply corrugated cardboard box.

Comparison of Safety Levels(Security Levels)

Fire extinguishing systems are all hazardous materials, but with different hazard classes.

We will fill the fire tube fire protection system with 1.0 para 2.5 MPA pressure.

In transport, the fire detection tube systems are classified as hazardous materials and have a hazard class of 2.2.

Aerosol fire extinguishing agent is normally highly concentrated and looks like a light brown mud, it is not under any pressure.

Aerosol fire extinguishing agents only generate a certain high temperature after a redox reaction.

For transport purposes, aerosols have a hazard class 9.1 or are simply classified as chemically sensitive goods.

Assim sendo, aerosols have a much lower safety margin than fire detection tubes and are easier to transport.

Fire Detecting Tube and Aerosol: Which is a Better Suppression System?

By comparing the fire detection tube and aerosol, we have come to the following conclusions:

• Aerosol systems have a wider range of applications than fire detection tube systems.
• They both have the same installation complexity.
• Fire extinguishing agents for fire detection tubes are a little cleaner than aerosol extinguishing agents, but both are clean extinguishing agents.
• The extinguishing efficiency of aerosol devices is higher than that of fire detection tubes.
• Aerosol fire suppression systems are safer than fire detection tubes.
• Packaging is slightly more complicated when it comes to fire detection tubes.
• The spray release time for fire tubes is a little shorter than for aerosols.

From the above conclusions, we conclude that aerosol fire extinguishing systems are better than fire-detecting extinguishing systems, but fire-probe tube fire extinguishing systems are also excellent.
