What is a heptafluoropropane fire extinguishing system? What are its characteristics and are it more suitable for use in which situations? Let's hear from Siemens gas fire extinguishing system manufacturers in detail

What is a heptafluoropropane fire extinguishing system

The heptafluoropropane (HFC-227ea) fire extinguishing system is an efficient fire extinguishing equipment, and its fire extinguishing agent HFC-227ea is a colorless, odorless, low toxicity, good insulation, and non secondary pollution gas with zero ODP to the atmospheric ozone layer. It is currently one of the alternatives to halogenated alkanes 1211 and 1301. Practical scope: The heptafluoropropane fire extinguishing system is mainly suitable for computer rooms, communication rooms, distribution rooms, oil immersed transformers, self-contained generator rooms, libraries, archives, museums and receipts, cultural relics databases, and other places. It can be used to extinguish electrical fires, liquid fires, melting solid fires, solid surface fires, and gas fires that can cut off the gas source before extinguishing.

Attention: The heptafluoropropane fire extinguishing system cannot be used for fires involving the following substances:

(1) Chemical products and mixtures of oxidants, such as nitrocellulose, sodium nitrate, etc.

(2) Active metals such as potassium, sodium, magnesium, aluminum, uranium, etc.

(3) Metal oxides, such as potassium oxide, sodium oxide, etc.

(4) Chemical substances that can decompose on their own, such as hydrogen peroxide, diamine, etc.

What are the characteristics of heptafluoropropane fire extinguishing agents?

It extinguishes fire chemically and is a new and efficient fire extinguishing agent with low extinguishing concentration, less use of steel cylinders, and less space occupied.

The heptafluoropropane fire extinguishing agent is non-conductive and does not contain water, and will not cause harm to electrical equipment, magnetic tapes, data, etc. Heptafluoropropane is a colorless and odorless gas with a depletion potential (0DP) of 0 for the ozone layer, which meets the requirements of the Montreal Convention and is an ideal substitute for halon fire extinguishing agents. The minimum design concentration is 7.35% (V/V); The highest concentration of non-toxic reaction (NOAEL) is 9% (V/V), which can be used in human areas.

The heptafluoropropane automatic fire extinguishing system consists of three main parts: fire alarm system, fire extinguishing control system, and fire extinguishing device. The fire extinguishing device consists of two parts: fire extinguishing storage device and pipeline system.

Applicable occasions for heptafluoropropane fire extinguishing agent:

Can extinguish various types of fires A, B, and C, and can be used safely and effectively in places with people;

After spraying the medication, it is required to leave no traces or to clean areas with difficult residues;

The security zone contains valuable items, priceless treasures, precious archives, and software, etc;

Especially suitable for telecommunications control rooms, airport control rooms, bank vaults, archives, libraries, computer rooms, and other occasions.

Fluoropropane fire extinguishing agent is not suitable for:

Chemical substances such as nitrocellulose and black gunpowder that can rapidly oxidize without air;

Storage and production sites for active metal potassium, sodium, magnesium, titanium, and uranium;

Storage facilities for metal hydrides.
