The fire Detecting Tube System is a popular

Fire Detecting Tube Device is recognized as a new fire extinguishing device, it is widely used in practical engineering projects and become more and more popular.

So compared with other conventional fire suppression systems, what are the advantages of fire detection tube devices? And how to choose a fire detection tube to install in practical engineering?

Fire Detection tubes have their unique advantages, and are widely applied in electrical cabinets, cable tunnels, kabelbrunnar, and some other smaller spaces, people in the social are pay more attention to this product, and it has become remembered and recommended by more and more people.

In the worldwide market now 3 styles of fire extinguishing agents can be applied in tube fire systems, there are:

1. gas of Carbon Dioxide.
2. gas of HFC-227ea.
3. Gas of NOVEC 1230.

In the Chinese market, at present, we mainly use carbon dioxide and HFC-227ea, and in the European and American markets now there is also NYHET 1230.

This device is made up of a storage cylinder, siphon tube, container valve, fire detection pipe, and pressure gauge, when we install this device in a protection space according to a certain distance, when fire starts, the fire detection tube near the flame will get sensor of heat, and the location of which reaching the melting point will get blasting, the fire extinguishing agent run out by way of the outlet or nozzle, and then total flooding the hazards to suppress fire.

Compare Chart of Fire Detecting Tube System and Other Fire Suppression System

To show you why the device is more and more popular, below is a comparison chart between fire detection tube devices with other conventional fire suppression systems, see from the below chart you will see their difference, advantages, and features:

Comparison Item	Conventional Fire Suppression System	Fire Detection Tube Device System
Protective Object	Large enclosed space as fire protective object, take the whole room as protection zone, not be able to install inside the equipment.	There is a small space or cabinet in the large enclosed space and, till exempel, a distribution cabinet, or communication cabinet, inside the device.
Construction and Installation	1. Complex in construction, and long construction period, need special cylinder room; 2. Need smoke detector and heat detector; 3. Not be able to reach small space for fire protection; 4. Complex pipes to install.	1. Easy to install, and short construction period, not require cylinder room; 2. Do not need smoke detector and heat detector; 3. Can be able to reach small space for fire protection; 4. Easy to install.
Maintenance and Operation	1. Need special fire power supply; 2. As it has electronic components, easy to get false alarms because of oil, dust, and electromagnetic interference; 3. Electronics components will easy to lose operational function because of vibration and crash; 4. The System is a bit complex and needs a professional technician to do maintenance.	1. Do not need a power supply; 2. A fire detection tube is a non-mental tube, that will not be able to affected by oil, dust, or electromagnetic interference, not easy to get false alarms; 3. Not have electronic components; 4. The System is easy to do maintenance.
Safety Performance	Design for total flooding of the fire protection room, use a lot of fire extinguishing agent to suppress, when works the people must leave	Design for total flooding the fire for protective objects, less fire extinguishing agent to suppress, when works people don’t need to leave.
Fire Extinguishing Effectiveness	1. Handla om 30 seconds delay before extinguishing the fire, because it is controlled by a fire alarm panel and set 30 seconds delay; 2. The fire extinguishing agent is discharged to the protection room, not for the protective object directly.	1. Extinguishing the fire immediately when the fire detection tube detects out fire; 2. Extinguishing the fire immediately when the fire detection tube detects out fire.
System Cost	The system is complex and needs a special cylinder storage room, and also some have piping systems, engineering costs, and maintenance costs are very high.	The system is simple, does not need a special cylinder store, maximum to reduces engineering cost and maintenance costs.

Comparison Table

From the above chart, we can see that compared with conventional gas fire suppression systems, fire detection tube device, and its system has many advantages.

Expound

In practical engineering, we are more consider with 2 factors, one Characteristics of a fire protection zone, another is engineering investment and operation management and cost.

So, When the protection zone is large in area or volume and needs to flood the room, use a conventional fire suppression system better, when the protection zone is small, till exempel, an electrical cabinet, or elevator control cabinet, use a fire detection tube as solution because it is easy to install and low in cost.

One red color fire detection tube is very long, the length is about 25 meters or 30 meters for each device, so one or two fire detection tube devices can make fire protection of several or even tens of electrical cabinets in the hazard, and then its average cost is very low.

This system has come out of China and now many enterprises both in China and overseas have adopted it as a main fire prevention solution; Some research institutes and government organizations even strongly recommend this product for some specific fields.
