It can be used on many types of fires.
. HFC-227ea was tested at the design concentrations of 76 using the Halon-1301 piping system and at 76 and 88 using the optimal system. In both series of tests HFC- 227ea extinguished all the test fires most of them within the discharge time. On a weight-of-agent basis HFC-227ea is a very effective gaseous extinguishing agent.
It leaves no residue and has acceptable toxicity for use in occupied spaces at design concentration. Product Name Risk Design Concentration FSL CG2Class A Standard 79 FSL CG2Class A Cables 85 FSL CG2Class B 90 The design concentrations include a safety factor of 13 over the extinguishing concentration. HFC-227ea is stored as a liquid and dispensed into the hazard as a colorless electrically non-conductive vapor that is clear and does not obscure physical vision.

All cylinders are super pressurized with dry nitrogen to a pressure of 25 bar or 42 bar at 21C. Dampers and vents are closed before and during discharge in order that the correct agent concentration can be reached and maintained.
A The system shall be a Total Flood HFC-227ea Suppression System supplied by. The design of such a system requires that the Unique227 chemical agent be discharged from its container within 10 seconds and be thoroughly mixed throughout the protected volume reaching a minimum concentration level of 7. It is environmentally friendly.
HFC227ea is stored in specially designed cylinder assemblies. Provide sufficient amount of extinguishing agent HFC 227 ea considering the following key points when computing volume to verify suitability and to establish design limitations. 42 bar 610 psi for greatest system design flexibility Wide selection of cylinder sizes from 5 240 L 12 -590 lb.
It has acceptable toxicity for use in occupied spaces at design concentration. FM-200 clean agent fire extinguishing systems are the most widely used of all the halocarbon gaseous agents and is universally accepted as the best agent used to replace Halon 1301. HFC 227ea is a clean agent as describe in NFPA 2001.
It suppresses fire by a combination of chemical and physical mechanisms without affecting the available oxygen.

Containment to prevent for re-flash and reignition. DESIGN CONCENTRATIONS NAFFCO HFC-227ea can be used to extinguishing Class A fuels surface fires of ordinary combustible materials Class B fuels flammable liquids and gases and Class C fuels fire involving energized equipment occurring within a confined space. Hochiki HFC-227ea is suitable for use on Class A Class B and.
HFC-125 120 124 86 HFC227ea 80 93 61 HFC-236fa 87 90 68 CONCLUSIONS The current extinguishing design standards for Class A fires do not adequately provide for suppression ie. It has Zero ozone-depleting poten- tial low global warning potential and short atmospheric lifetime. It is colourless odourless and electrically non-conductive.
FM-200 is a chemical agent used primarily in total flooding systems and is used in over 200000 systems installed worldwide. Accordance with the guidelines contained in NFPA 2001. Cylinders are available in various sizes.
After discharge of BAVARIA. Volume of hazard area. The minimum design concentration for total flood applications should be in accordance with NFPA 2001.
Fire extinguishment of the three mock-up cabinets and the wood crib took more time 15 to 30 s. Requires minimal container storage space Zero ozone depleting potential Low global warming potential Short atmospheric lifetime. August 2014 Page 1 of 6 Part 1 - GENERAL.
SPECIFICATIONS HFC-227ea is manufactured to these specifications. With a Fike designed fire protection system you can count on speed and efficiency in your fire protection and much more. HFC-227 fire extinguishant is a compound of carbon fluoride and hydrogen.
Specific volume of Clean agent. One archive room is 115 meter in length 9 meter in width and 3 meter in height the minimum environment temperature is 20 altitude height is no more than 500 meters we use a cabinet type non-piping hfc-227ea fm200 fire suppression device as a total flooding system for solution please calculate the quantity of the hfc-227ea fire. It is a halocarbon chemical nomenclature Heptafluoroprapane.
It is also equipped with Switch-in-Gauge unit design to monitor health of cylinder pressure. Each cylinder is equipped with an identification nameplate indicating the quantity of HFC227ea pressurisation level and filling station.
