EXTINGUISHING AGENT SPECIFICATION:
HFC 227ea is a clean agent as describe in NFPA 2001. It is a halocarbon chemical nomenclature Heptafluoroprapane.
SRI’s HFC 227ea gas extinguishing agent is an Underwriters Laboratories (UL) recognised component and complies with NFPA Standard 2001.
Ozone Depletion Potential (ODP): 0
Atmosphere Lifetime: 37 years
Global Warming Potential 100-year time horizon (CO2=1.0): 2900
The required agent quantity is based on the volume of protected area at the lowest expected ambient temperature and concentration required. To obtain the minimum agent quantity required, use the following equation:
W = (V/S) X ( C/100 -C)
W = weight of Agent required V = volume of protected area volume
S = 0.1269 + 0.000513 T
C = Required HFC-227ea Design Concentration (% by volume) at Design Temperature (t).
T = Design temperature in protected area (°C)
Heat of Vaporization at Boiling Point Thermal Conductivity of Liquid @ 25°C Viscosity, Liquid at Centipoise 25°C Relative Dielectric Strength @ 1 atm Solubility of Water in Agent @ 21°C Saturated Vapor Density @ 20°C (68°F) Ozone Depletion (ODP)
No Observed Adverse Euect Level (NOAEL) Lowest Observed Adverse Euect Level (LOAEL)
