DSPA Aerosol for Battery Storage (BESS)

Battery Energy Storage Systems (BESS) play a crucial role in modern energy systems.However, the growing use of this technology also increases the risk of lithium-ion battery fires, which can cause damage and harm.

Traditional fire extinguishers are ineffective in dealing with these fires, but DSPA aerosol fire suppression provides a safe, effective, and reliable solution.

The DSPA aerosol suppresses fires by chemically interrupting the burning process. It also has a certified hold-time of at least 30
minutes, which allows to not only put out the fire but also to prevent further re-ignition of
battery gasses.

Additionally, our Aerosol generators have a compact design, which makes them a practical choice for protecting
(BESS) containers. By using our DSPA aerosol, businesses can
rest assured that their energy supplies and facilities are secure from the dangers of lithium-ion fires.

Features

  • A lithium-Ion battery is difficult to extinguish. Normal extinguishers, which are based upon oxygen reduction, will not be able to extinguish a lithium-Ion fire. Neither can it be extinguished with water based extinguishing systems.
  • DSPA aerosol generators are very efficient, the lowest mass of suppression agent (grams per cubic meter) is required to protect any enclosure.
  • DSPA aerosol has the unique characteristic of having an EN-15276-1 and ISO-15779 certified hold-time of at least 30 minutes, which is the certifiable maximum. The tests conducted even exceeded 30 minutes. This time refers to the duration it takes for the agent concentration to drop below a specified level at a designated height, preventing reignition. Other suppression solutions will not exceed 10 minutes.
  • DSPA aerosol is highly effective in suppressing gas fires, including those caused by battery fires. When a lithium-ion cell enters thermal runaway, it begins venting flammable gases. In comparison to conventional gas suppression systems, DSPA requires a significantly lower amount of extinguishing agent to effectively control the fire.
  • Unlike other suppression agents, DSPA generates little to no pressure buildup, eliminating the need for pressure relief valves. As a result, no structural modifications to containers are necessary.
