What gases are mixed in the IG541 gas extinguishing system?

The "541" in IG541 is nitrogen, argon, and carbon dioxide, respectively, accounting for %.

IG-541 mixed gas fire extinguishing agent is a gas mixed with nitrogen, argon and carbon dioxide gas in a certain proportion, because these gases are naturally present in the atmosphere, and the most abundant, so it has no depletion of atmospheric ozone (ozone depletion potential ODP=0), and will not have an impact on the earth's "greenhouse effect", let alone produce chemicals that have a long-term impact on the life of the atmosphere. The gas mixture is non-toxic, colorless, odorless, non-corrosive and non-conductive, neither supports combustion nor reacts with most substances. From the perspective of environmental protection, it is an ideal fire extinguishing agent.

The IG-541 mixed gas fire extinguishing system consists of automatic fire detector, automatic alarm controller, automatic control device, fixed fire extinguishing device, pipe network, nozzle, etc. It has three starting modes: automatic start, manual start and mechanical emergency start. According to the requirements of use, it can be composed of unit independent system, combined distribution system, and adopt the full submersion mode to realize the fire protection of a single protection area and multiple protection areas.

It is mainly used in computer rooms, communication rooms, power distribution rooms, oil-immersed transformers, self-provided generator rooms, libraries, archives, museums and bills, cultural relics databases and other places where people often work and can be used to extinguish electrical fires, liquid fires or soluble solid fires, solid surface fires and gas fires that can cut off the gas source before extinguishing the fire, but can not be used to extinguish Class D active metal fires.

The IG541 gas fire extinguishing system, also known as the smoke exhaustion gas fire extinguishing system, uses a gas fire extinguishing agent that is a fire extinguishing agent mixed with 52% nitrogen (N % argon (AR) and 8% carbon dioxide (CO2). The IG541 gas fire extinguishing system will not have any chemical reaction when extinguishing the fire, does not pollute the environment, is non-toxic and non-corrosive, has good electrical insulation properties, and the fire extinguishing process is clean, and no trace will be left after the fire is extinguished, and it will not pose a hazard to the protected equipment. Therefore, if the equipment in the protection area is too delicate and the very large data center cannot have even the slightest corrosion, the IG541 fire extinguishing system can be used.

Nianhai fire IG541 gas fire extinguishing system cylinder service life of up to 30 years, selection valve, pressure reducing valve made of 304 stainless steel, to ensure the reliability of the system, fire extinguishing principles and solutions can be asked.

First of all, IG541 became Inergen, the chemical name is smoke burning, and it is the earliest mixed gas fire extinguishing equipment developed by Ansul in the United States; Secondly, the "541" in IG541 is nitrogen, argon, and carbon dioxide, accounting for %; Finally, the gas released by IG541 will not cause damage to the atmosphere, and extinguishing a fire will not cause harm to the human body.

The IG541 mixed gas fire extinguishing system consists of: fire extinguishing agent storage bottle group, pneumatic manual starting head, selector valve, check valve, pneumatic check valve, manifold safety valve, low-pressure pressure relief valve, pressure reducing device, pressure relay, electromagnetic pilot valve, starting gas cylinder group (including gas cylinder valve, pressure gauge), and Yong group.

Ig541 is a gas mixture. IG541 fire extinguishing agent is composed of 52% nitrogen, 40% argon and 8% carbon dioxide, which is a colorless, tasteless, non-toxic and non-conductive gas.

The ozone depletion potential in IG541 ODP=0, the greenhouse effect potential GWP=0, IG541 has a short time in the atmosphere, and it is a green and environmentally friendly fire extinguishing agent.

The main components of the IG541 system are: gas storage cylinder, collapse-sensitive container valve, check valve, selection valve, driving device, manifold, metal hose, pressure reducing device, nozzle, pressure feedback device, control panel, etc.

IG541 mixed gas fire extinguishing system. IG541 mixed gas fire extinguishing system is mainly suitable for computer room, communication room, power distribution room, oil-immersed transformer, self-provided generator room, library, archives, museums and bills, cultural relics and other places where people often work, can be used to extinguish electrical fires, liquid fires or soluble solid fires, solid surface fires and gas fires that can cut off the gas source before extinguishing the fire, but can not be used to extinguish Class D active leakage Wangxiang metal fire.

Answer]: B For the ig541 mixed gas fire extinguishing system, the fire extinguishing impregnation time should comply with the following regulations:

1) For fires on solid surfaces such as wood, paper, and fabric, it is advisable to use 20min.

2) For the fire of electrical equipment in the communication room and electronic computer room, it should be used for 10min.

3) Other solid groups are resistant to surface fire, and it is advisable to use the blocking finger l0min.
