HFC-227ea Fire Extinguishing Agent
HFC-227ea is a widely used hydrofluorocarbon developed in recent years. It has been used as fire extinguishing agent, an aerosol propellant and refrigerant.
HFC-227ea fire extinguishing agent
HFC-227ea (HFC-227ea/FM200) is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects. It belongs to polyfluorinated alkanes with a molecular formula of C3HF7; it is colorless, odorless, low-toxic, non-conductive, does not pollute the protected object, and will not cause damage to property and precision facilities.
HFC-227ea fire extinguishing agent has the characteristics of cleanliness, low toxicity, good electrical insulation, high fire extinguishing efficiency, and does not damage the atmospheric ozone layer. It is the better clean gas to replace halogenated hydrocarbon fire extinguishing agents.
HFC-227ea Application
HFC-227ea fire extinguishing agent has good cleanliness – it completely vaporizes in the atmosphere without leaving any residue, and has good gas phase electrical insulation. It is suitable for extinguishing electrical fires, liquid fires or fusible solid fires, solid surface fires, and gas fires that can cut off the gas source before extinguishing by full flooding fire extinguishing.
It protects computer rooms, communication rooms, substations, precision instrument rooms, generator rooms, oil depots, chemical flammable warehouses, book libraries, databases, archives, vaults and other places.
HFC-227ea fire extinguishing system has a reasonable structure and reliable operation. It has been widely used in important places such as electronic computer rooms, archives, program-controlled switch rooms, TV broadcasting centers, financial institutions, government agencies, etc.
HFC-227ea Features
- The storage device has excellent sealing performance. The container valve of the fire extinguishing agent storage device adopts a reverse pressure piston structure, and the sealing ring is made of high-quality materials and finely processed, with ideal sealing effect;
- The electromagnetic drive is accurate and reliable. The valve of the electromagnetic drive device is exquisitely designed, with a small driving current and flexible and reliable operation;
- The locking mechanism prevents misoperation. The storage device and the drive device are both equipped with locking mechanisms to prevent misoperation during transportation;
- Pressure gauge switch. The fire extinguishing agent storage device and the electromagnetic drive device are equipped with pressure gauge switches to prevent leakage caused by damaging the pressure gauge during transportation;
- The selector valve structure is reasonably designed. Make sure to open the selector valve first and then open the storage device to release the fire extinguishing agent;
- Mechanical manual start. The electromagnetic drive device, selector valve and fire extinguishing agent storage device can all be manually started, which is safe and reliable;
- Various specifications and forms. The storage cylinders have six specifications of 40L, 70L, 100L, 120L, 150L,
and 180L, and the hanging devices have five specifications of 14L, 20L, 30L, 40L, 50L, and 60L. The structural forms include unit independent system, combined distribution system, main and standby conversion system, cabinet device, hanging device, etc., which can fully meet the requirements of various design schemes; - The system structure is reasonable. The installation layout of each component of the system is reasonable and concise, which is convenient for maintenance, inspection and operation;
- Mature technology and quality assurance. The product has been in production for many years, and the process is mature;
- The technical force is strong, and the after-sales service is in place.
HFC-227ea can reliably extinguish Class B and C fires and electrical fires at a low fire extinguishing concentration; the storage space is small, the critical temperature is high, the critical pressure is low, and it can be liquefied and stored at room temperature; it does not contain particles or oily residues after release, and has no destructive effect on the atmospheric ozone layer (ODP value is zero), and the residence time in the atmosphere is 31~42 years, which meets environmental protection requirements.
HFC-227ea Fire extinguishing device
HFC-227ea is gaseous at room temperature, colorless, odorless, non-conductive, non-corrosive, without environmental restrictions, and has a short atmospheric retention period. The fire extinguishing mechanism is mainly to interrupt the combustion chain, and the fire extinguishing speed is extremely fast, which is beneficial for the rescue protection of precision electronic equipment and valuables.
HFC-227ea fire extinguishing devices are divided into two types: with pipe network and without pipe network (cabinet type, hanging type).
Among them, the pipe network system is further divided into an internal storage pressure system and an external storage pressure system. The main difference is the different transmission distance of the fire extinguishing agent. The transmission distance of the internal storage pressure system is generally no more than 30 meters, and the transmission distance of the external storage pressure system can reach 150 meters.
HFC-227ea Fire extinguishing system composition
The gas fire extinguishing agent storage bottle of the pipe network HFC-227ea fire extinguishing system is usually placed in a special cylinder room and connected through a pipe network. When a fire occurs, the fire extinguishing agent is transported from the cylinder room to the protection area where the fire needs to be extinguished, and the fire is sprayed through the nozzle to extinguish the fire.
The HFC-227ea gas fire extinguishing system includes a fire extinguisher bottle group, high-pressure hose, fire extinguishing agent one-way valve, starter bottle group, safety pressure relief valve, selection valve, pressure signal device, nozzle, high-pressure pipeline, high-pressure pipe fittings, etc.
Advantages and Disadvantages
1. The pipe network system sprays through the pipe network, and the nozzles are evenly distributed, so the spraying is uniform, and the fire extinguishing effect is good, while the non-pipe network is generally sprayed directly by the box nozzle, and the spraying is not uniform enough;
2. The pipe network needs to set up a separate cylinder room and pipe network, while the non-pipe network does not need it. If only one area is protected, the cost of the pipe network system is high from an economic point of view;
3. If there are multiple areas, the pipe network system can use the same system to protect multiple protection areas. Fires occur in different protection areas, and targeted spraying is required, while the non-pipe network requires each protection area to set up a separate cylinder and fire extinguishing agent. At this time, the price of the non-pipe network is relatively high;
4. The cylinders of the pipe network system are in the cylinder room. Because of the long distance, the pressure is required to be high, generally 4.2MPa. Some are 5.6MPa;
5. The cylinder of the non-pipeline system is in the protection zone. Because it is in the protection zone, the pressure cannot be too high, so 2.5MPa is generally selected.
HFC-227ea Storage conditions
HFC-227ea is not easy to react to and is a stable material. Liquefied gas is stable when used as a propellant and must be stored in a metal tank in a cool and dry place.
In addition, HFC-227ea can also be used as a refrigerant and aerosol propellant.
