Product Details

HFC 227ea /FM 200 fire gas extinguisher
(Sevofluoropropane fire extinguishing system)
 
 
I. Fire Extinguishing Principle
It is mainly physical fire extinguishing function:
1. Cooling the reserve, dispersing fire extinguishers and consuming oxygen to achieve fire prevention effect.
2. Sevofluoropropane fire extinguishing agent sprays into the protected area in the form of liquid. In the nozzle, liquid fire extinguishing agent quickly enters the gas which needs to absorb a large amount of heat and reduces the temperature around the protected area and the flame.
3. Heptafluoropropane fire extinguishing agent is composed of macromolecule, which needs to absorb heat when some of the key cracks occur.
4. The presence of fire extinguishers and flames in the protected area will reduce the concentration of oxygen, thus reducing the burning rate.
 
II. Main Advantages
Colorless, odorless, non-conductive, non-corrosive, no environmental restrictions, short atmospheric retention time. Its non-toxic reaction (NOAEL) concentration is 9%, toxic reaction (LOAEL) concentration is 10.5%, its design concentration is generally less than 10%, which is safe to human body. It is characterized by good cleanliness (complete vaporization in the atmosphere without residue), good gas-phase electrical insulation and good physical properties suitable for use in fire extinguishing systems.
