Ultra fine dry powder manufacturers: IG541 and heptafluoropropane are typical representatives of inert gas fire extinguishing agents and chemical gas fire extinguishing agents respectively, and these two products are also outstanding in gas fire extinguishing and are deeply loved by the majority of users. Next, the main differences between these two types of fire extinguishing agents are introduced in detail, and the contents are summarized as follows:
1、 Main advantages of inert gas extinguishing agent:
1. Pure "green" gas extinguishing agent.
2. There is no cold shock effect during spraying, which will not cause visual impairment.
3. No decomposition products.
2、 Main advantages of heptafluoropropane gas extinguishing agent:
1. For the same protected object, the amount of storage bottle is less than that of inert gas extinguishing agent.
2. The pressure level of the storage bottle is low.
3. The fire extinguishing is fast and the fire extinguishing time is shorter.
4. There are more application forms, such as hanging type, cabinet type, pipe network type and other application forms.

3、 In large precision equipment rooms, which one is more advantageous, IG541 or heptafluoropropane?
For precision equipment room and computer room, IG541 and heptafluoropropane are suitable extinguishing agents, which should be selected according to the actual situation and their respective characteristics. For the pipe network system under the same conditions, which is more advantageous, IG541 or heptafluoropropane? We can analyze it from the fire extinguishing mechanism:
1. Heptafluoropropane extinguishes fire quickly, which is of great significance for the rescue and protection of important equipment!
Heptafluoropropane is a chemical gas fire extinguishing agent. The fire extinguishing mechanism is mainly to block the combustion chain, mainly chemical inhibition, and fire extinguishing is rapid; The fire extinguishing mechanism of IG541 and other inert gas fire extinguishing systems is mainly to reduce oxygen concentration and suffocate, and the fire extinguishing speed is relatively slow.
According to the requirements of gas fire extinguishing systems and components (gb25972), the z-large injection time of heptafluoropropane fire extinguishing system is 10s, and the z-large injection time of inert gas fire extinguishing systems such as IG541 is 60s. Heptafluoropropane fire extinguishing speed is faster, which is of great significance for more effective rescue protection equipment for precision equipment and electronic machine rooms.
2. The inert gas fire extinguishing system has no problem of extinguishing agent consumption, and the fire extinguishing efficiency is more lasting!
The fire extinguishing mechanism of heptafluoropropane is mainly to block the combustion chain, and the fire extinguishing speed is extremely fast, but this kind of fire extinguishing agent is required to be distributed to the protected area faster and more evenly. If the fire part of the protected area cannot form sufficient concentration of fire extinguishing agent steam quickly, and the combustion chain cannot be completely interrupted, the fire extinguishing agent will be continuously consumed, the combustion will continue to develop, and Z may eventually lead to fire extinguishing failure.
For deep fire of large equipment, if the fire extinguishing agent penetrates slowly, there may be a situation that individual parts cannot quickly form sufficient fire extinguishing concentration, and there is a risk of fire extinguishing failure.
In contrast, inert gas fire extinguishing systems such as IG541 can extinguish the fire through suffocation, and there is no problem of extinguishing agent consumption. As long as there is a qualified protective area enclosure, it can ensure a better fire extinguishing effect.
Therefore, for large-scale precision equipment that may have deep fire, inert gas fire extinguishing systems such as IG541 may have more advantages.
