What Is Automatic Fire Suppression?

The automatic fire extinguishing system is divided into two categories according to the main materials of fire extinguishing: heptafluoropropane and mixed gas automatic fire extinguishing system.

Automatic fire extinguishing system

There are two main types of automatic fire extinguishing systems: automatic water fire extinguishing and automatic

Automatic gas fire extinguishing

Heptafluoropropane

Features: Heptafluoropropane (HFC-227ea) automatic fire extinguishing system is a high-efficiency fire extinguishing equipment. Its fire extinguishing agent HFC-ea is a colorless, odorless, low-toxicity, good insulation, and no secondary pollution gas. The ozone layer has zero depletion potential (ODP) and is the most ideal substitute for haloalkanes 1211 and 1301.

Scope of application: Heptafluoropropane fire extinguishing systems are mainly suitable for computer rooms, communication room, power distribution rooms, oil-immersed transformers, self-contained generator rooms, libraries, archives rooms, museums and bills, cultural relics databases, etc. Liquid fire or meltable solid fire, solid surface fire and gas fire that can cut off the gas source before extinguishing.

Note: The heptafluoropropane fire extinguishing system cannot be used for the following fires:

(1) Chemicals 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 and sodium oxide.

(4) Chemical substances that can decompose by themselves, such as hydrogen peroxide and hydrazine.

mixed composition

Features : Mixed gas fire extinguishing agent is a gas made by mixing nitrogen, argon and carbon dioxide gas at a certain ratio. These gases are naturally present in the atmosphere, and there is no loss of the ozone layer in the atmosphere. "Effect", and the mixed gas is non-toxic, colorless, odorless, non-corrosive, non-conductive, does not support combustion, and does not react with most substances, is an ideal environmentally friendly fire extinguishing agent.

Scope of application : It can be used to extinguish electrical fires, liquid fires or meltable solid fires, solid surface fires and gas fires that can cut off the gas source before extinguishing. It is mainly suitable for places where people often work, such as computer rooms, communication rooms, power distribution rooms, oil-immersed transformers, self-contained generator rooms, libraries, archives, museums, bills, cultural relics databases, etc.

Note: Mixed gas fire extinguishing agents should not be used to fight Class D live metal fires.

carbon dioxide

Features : Carbon dioxide fire extinguishing agent has the characteristics of low toxicity, no fouling of equipment, good insulation performance, strong fire extinguishing ability, etc. It is a popular gas fire extinguishing product in the domestic and foreign markets, and it is also an ideal product to replace haloalkanes.

Scope of application : It can be used to extinguish fires of gas, liquid or meltable solids (such as paraffin, asphalt, etc.), solid surface fires, deep fires of some solids (such as cotton, paper), electrical fires, etc. Suitable for computer room, data storage, central control room, communication room, power distribution room, library, archives, museum, hangar, car garage, cabin, cotton, tobacco, fur storage, and fire hazards in production operations Places, such as immersion tanks, drying equipment, cooking stoves, paint production lines, pulverized coal silos, etc.
