Aerosol fire suppression

At LOXXER, we use AF-X aerosol fire suppression systems in our Li-ion cabinets and containers. This advanced technology is not only reliable in controlling a lithium-ion battery fire but is also completely safe for humans, animals, and the environment.

Operation of the aerosol in the cabinets

The LOXXER battery storage and charging cabinets are equipped with two smoke detectors that ensure fast detection of a lithium-ion battery going into Thermal Runaway. So, upon the first smoke detection, the aerosol is activated to respond immediately to the situation.

 

This advanced technology is not only applied in our lithium-ion charging cabinets but is also utilized in our lockers, LOX10. Additionally, our containers can be equipped with this reliable principle to provide maximum safety and protect businesses against the risks of lithium-ion battery fires.

KIWA certification and testing

To test the effectiveness of our cabinets with the aerosol, we conducted extensive KIWA tests with lithium-ion batteries in Thermal Runaway. These tests demonstrate that our cabinets can manage the battery for a minimum of 90 minutes and ensure that the remaining batteries in the cabinet are protected.

 

The graph shows the various parameters measured during one of the multiple tests.

(1) Here, you can clearly see from the temperature measurement that the battery is in Thermal Runaway.

(2) The aerosol is activated. To clearly demonstrate that the aerosol can control a battery fire, the activation was delayed for a few seconds in the test, allowing the battery to clearly be in a further stage of Thermal Runaway.

(3) Finally, you can see here that the battery was cooled and monitored for at least 90 minutes.

How does the extinguishing agent in the AF-X unit work?

The aerosol operates based on 2 reactions:
 

  • Physical reaction
    By absorbing the energy required for the chemical reaction, it results in a cooling effect.
     
  • Chemical reaction
    The unstable radicals (OH) react faster with potassium (K) than the combustion reaction and create stable potassium hydroxide (KOH). Clarification: During this reaction, certain chemicals in the aerosol, such as potassium (K), react with the fire source. This prevents the burning materials from continuing to fuel the reaction that sustains the fire. As a result, the fire is effectively extinguished.
