Fike HFC-227EA C 1 07 01

APPROVALS complies with NFPA 2001 current edition Fike systems are UL listed FM approved for Clean Agent Suppression Systems UL Listed Ex 4623 FM Approved 0Y4A8 AF USCG 162.161 2 0 provides superior fire protection in a wide range of applications from electrical equipment to industrial applications using flammable liquids is ideal for applications where clean up of other media presents a where weight versus suppression potential is a factor where an non conductive medium is needed and where people compatibility is overriding factor When environmental impact is a consideration HFC 227ea particularly useful It has zero ozone depleting potential low global warming and a short atmospheric lifetime These characteristics make it suitable only for new installations using Fike total flooding systems but also for 1301 replacement applications is an odorless colorless liquefied compressed gas See Physical Table for additional information It is stored as a liquid and dispensed the hazard as a colorless electrically non conductive vapor that is clear and not obscure vision It leaves no residue and has acceptable toxicity for use in spaces at design concentration HFC 227ea extinguishes a fire by a of chemical and physical mechanisms HFC 227ea does not displace and therefore is safe for use in occupied spaces without fear of oxygen is an effective fire extinguishing agent that can be used on many types fires It is effective for many surface fires such as flammable liquids and most combustible materials a weight of agent basis HFC 227ea is a very effective gaseous extinguishing The HFC 227ea extinguishing concentration for normal Class A is 6.25 7 by volume The minimum design concentration for flood applications should be in accordance with NFPA 2001 is manufactured to these specifications Mole 99.0 Minimum Acidity ppm by weight 3.0 Maximum Water content by weight 0.001 Maximum Non volatile residues gram 100mL 0.05 Maximum toxicology of HFC 227ea compares favorably with other suppression agents LC50 of HFC 227ea is greater than 800,000 ppm HFC 227ea has been for cardiac sensitization via test protocols approved by the United Environmental Protection Agency Test results show that cardiac tolerance HFC 227ea is higher than that of other suppression agents and is acceptable safe use in occupied spaces HFC 227ea will decompose to form halogen when exposed to open flames The formation of these acids is minimized using Fike early warning detection systems and proper system installation properly applied and installed the generation of these by products of should be minimal No C 1.07.01 2 S 10th Street P O Box 610 Blue Springs Missouri 64013 0610 U S A 816 229 3405 816 229 4615 www fike com PROPERTIES Chemical Name Heptafluoropropane CF3CHFCF3 Molecular Weight 170.03 Boiling Point 760 mm Hg 2.55oF 16.4oC Freezing Point 204oF 131.1oC Critical Temperature 215oF 101.7oC Critical Pressure psia 422 psia 2912 kPa Critical Volume ft3 lbm cc mole 0.0258 274 Critical Density lbm ft3 38.8 621 kg m3 Specific Heat Liquid BTU lb Fo 77oF 25oC 0.283 1.184 kj kg oC Specific Heat Vapor BTU lb oF constant pressure of 1 ATM 77oF 25oC 0.808 kj kg oC Heat of Vaporization BTU lb at Boiling Point 57.0 132.6 kj kg Thermal Conductivity BTU h ftoF of Liquid 77oF 25oC 0.040 0.069 Viscosity Liquid lb ft hr 77oF 25oC 0.443 0.184 centipoise Vapor Pressure psia 77oF 25oC 66.4 457.7 kPa Ozone Depletion Potential 0 Estimated Atmospheric Lifetime years 31 42 LC50 Rats 4hrs ppm 800,000 Fike Corporation All Rights Reserved No C 1.07.01 2 March 2005 Specifications are subject to change without notice
