How is HFC-227ea stored?HFC-227ea is stored in specially designed cylinder assemblies. Cylinders are available in various sizes. All cylinders are super pressurized with dry nitrogen to a pressure of 25 bar at 21°C. Each cylinder is equipped with an identification nameplate indicating the quantity of HFC-227ea, pressurisation level and filling station.
What is a HFC-227ea total flooding system?HFC-227ea total flooding systems may be used for extinguishing fires of all classes within the limits specified in NFPA 2001 and ISO 14520-9 HFC-227ea suppresses a fire by a combination of Chemical (principally heat absorption) and physical mechanisms. The system should be designed to discharge within 10 seconds.
Is HFC-227ea better than CO2?In practical applications, if the fire suppression system is installed inside a battery module and a sufficient supply of HFC-227ea is available, its applicability surpasses that of CO 2. However, if the system is set in battery clusters or compartments where adequate HFC-227ea supply is challenging, CO₂ offers more stable suppression.
How does HFC-227ea suppress a fire?HFC-227ea suppresses a fire by a combination of Chemical (principally heat absorption) and physical mechanisms. The system should be designed to discharge within 10 seconds. HFC-227ea is clean, efficient, environmentally acceptable, and leaves no residue, thus minimizing any downtime after a fire.
How does HFC-227ea affect the thermal runaway of lithium-ion batteries?The total mass loss and heat release rate are inversely proportional to HFC-227ea concentration. The capacity of heat transfer between the heating rod and LIB has been reduced by HFC-227ea.
