Fire Suppression primarily for Class A,B and C fires.
What is an Aerosol Unit?
Aerosol Units are lightweight, handheld devices that use specialized aerosol technology (containing potassium nitrate) to suppress fires. The device releases a form of tiny solid particles suspended in a gas. These particles interfere with the fire’s chemical chain reactions, interrupting the combustion process. Even though the Aerosol units will not deplete oxygen levels, the gas released can reduce the concentration of oxygen in the fire area, which further suppresses the flames.
How does the Aerosol unit work?
First responders activate the aerosol by pulling a pin (until they hear a click), activating the unit. The Aerosol unit will start producing aerosol after an 8-second delay. Within 25 seconds, the unit will be discharged releasing a form of tiny solid particles suspended in a gas. At this time, the unit should be thrown into the fire, as close as possible to the fire source, for instance under an electric car close to the lithium battery. There is a bracket on the device to make it easier to throw the unit. Once the unit is placed correctly, it will absorb heat from the fire, leading to a reduction in temperature and Fire Suppression. The average hold time of the Aerosol unit is 30 minutes.
The Aerosol unit is designed not only to cause a heat reduction but also to reduce the amount of water or foam required. On top of that, the use of this device will make sure there is less to no collateral damage while leaving little to zero residue.
How to deploy the aerosol units is also shown in this animated video.
Important information:
- Close off the space with a Fire Blanket for an even better result.
- Always keep a safe distance from the fire.
- Training in proper aerosol unit deployment and handling is recommended for first responders and firefighters to ensure effective and safe use in fire control scenarios.
Fire Suppression tests with potassium aerosol units
We at Fire Isolator (part of T-ISS) conducted several successful tests for Fire Suppression with the aerosol units. The Fire Isolator concept has also been tested by our global customers and dealers, in cooperation with firefighting teams all over the world.

Environmentally friendly Fire Suppression
The Aerosol unit is an environmentally friendly device with a SNAP listing by EPA. This means that the technology of our device has been reviewed and approved by the EPA as an environmentally acceptable substitute for ozone-depleting substances. In other words, our Aerosol units are environmentally friendly and have a minimal impact on the ozone layer and the environment.
Part of the Fire Isolator Concept
The aerosol units are most effective when used in combination with our other tools, like the Fire Blanket and the Watermist lance. It is part of our Fire Isolator Concept: a concept for isolating and fighting EV car fires based on best practices and live testing. Because EV fires can’t be extinguished with just water, we asked ourselves ‘What combination of firefighting methods delivers the best result?’. This is how the Fire Isolator was born.
The Fire Isolator concept consists of 6 elements that, when used together, provide the best results in fighting EV fires in car parks, garages, or even on ferries:
- The use of a high-temperature fire blanket in order to isolate and suppress the fire and prevent collateral damage. Also, the use of a fire blanket will make the hold time of the aerosol unit significantly longer, because the smaller the volume (in M3), the longer the hold time will be.
- The aerosol units interrupt the chemical chain reaction from the fire.
- The use of a watermist lance to spray a water mist over the blanket, in order to reduce toxic fumes and smoke and to further cool down the car.
- A Thermal Imaging camera to monitor the heat of the fire.
- A dipping container in which the EV car needs to be submerged.
- A training in this concept.
