Energy storage system immersion water fire fighting system

What is immersion cooling technology?

Etica’s Immersion Cooling Technology sets a new standard for BESS fire prevention, offering continuous, reliable safety even under high-stress conditions. Unlike traditional air or liquid-cooling systems, this technology ensures active thermal management, keeping battery cells at optimal operating temperatures.

How do ESS fire protection systems work?

While these layers of protection help prevent damage to the system, they can also block water from accessing the seat of the fire. So, large amounts of water are needed to effectively combat the heat generated from ESS fires, and cooling the hottest part of the fire is often difficult.

Do ESS sprinkler systems need a cooling system?

Without adequate cooling, batteries can reignite, even after the initial fire is suppressed. For this reason, both FM DS 5-33 and NFPA 855 mandate the use of automatic sprinkler systems for ESS fire suppression.

What are the benefits of immersion cooling?

Unmatched Safety: Immersion cooling provides continuous heat absorption, mitigating thermal runaway and eliminating fire risks. Reliable Performance: Maintains optimal temperatures even during high-stress conditions or system failures.

Does NFPA 855 permit alternative fire suppression systems?

NFPA 855 also permits the use of alternative fire suppression systems if they successfully pass large-scale fire testing in accordance with Underwriters Laboratories (UL) 9540A, “Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems,” or an equivalent standard.

Why do ESS fires need a lot of water?

So, large amounts of water are needed to effectively combat the heat generated from ESS fires, and cooling the hottest part of the fire is often difficult. One of the top risks to ESS include accidental fire suppression system discharges.
