Aero-K® condensed aerosol fire suppression is a line protection solution for energy storage systems (ESS) and battery energy storage systems (BESS) applications. This includes in-building, containerized, and in-cabinet applications. Aero-K® systems provide highly effective battery room fire protection.
A lithium-ion battery or li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
The deep-seated nature of battery fires creates challenges relative to extinguishing for every extinguisher type.
Due to out-gassing before and during battery ignition, re-flash remains a possible hazard.
Unlike gas systems operating under high pressure that seek exit from the hazard area,
Aero-K® aerosol functions at low pressure and stays within the environment to deliver continual storage battery fire protection.
Gas systems will exit the hazard area through any openings. The Aero-K® aerosol keeps its buoyancy and enables openings which are not closable as opposed to the rapid exit of gas in high pressure gas systems.
Aero-K® state-of-the-art fire suppression technology delivers the most compact, lightest, and highly economical fire quenching solution. Our stainless steel, hermetically sealed, and exceptionally rugged canister – the Aero-K® generator – contains a solid and stable compound. When a fire occurs, these Aero-K® canisters automatically dispense propellant inert gases and ultra-fine particles which effectively put out fires utilizing smaller quantity of agent in terms of mass than any other type of standard fire extinguishing system.
Aero-K® fixed systems are utilized in various applications in a number of different industries including energy supply and energy storage. The potential hazard posed by lithium-ion batteries is present in these industries, which can result in an exceptionally difficult fire to control and quench due to several issues:
Some of the benefits of the Aero-K® fixed systems involving storage battery fire protection include:
The Aero-K® aerosol extinguishing product was tested for efficacy in putting out Li-ion battery fires. It was found that the Aero-K® agent successfully extinguished single and double cell battery fires. This testing was conducted in parallel with a large battery fire testing program. Fireaway Inc. contracted with DNV GL for testing to have its Aero-K® product line included in the program.
The following conclusions can be made from testing of Aero-K® aerosol fire suppression system.
