Eliminate foamy water and dirt-based chemicals. One Georgian businessman, Carver Fire, is mitigating the risk of lithium battery fires with a game-changing product: ELSA. It’s no ordinary suppression system; this is the first and only one that exploits the inherent capability of dry ice (solid CO₂) to achieve real-time, residue-free, and drastically effective cooling and was exclusively designed to control and contain notoriously unpredictable lithium battery infernos.
Behold the silent strength in a spectacular demo by ELSA and witness its capacity to suffocate fires in a snap. Carver Fire proudly announces that ELSA is already on the front lines and installed in a large American battery production plant. It sits sentinel there, protecting sensitive and very costly production machinery from worst-case scenario module fires. In a lightning-fast suffocation of battery fires and a cold, hard no-drop, no-dollop of water and after-effects, ELSA stops fires from spinning out of control, minimizing expensive downtime, and providing its operators with real, immediate physical value.
“We designed ELSA because battery fires aren’t necessarily always conceived to encounter typical suppression systems,”
says owner Carver Anderson of Carver Fire.
“Dry ice automatically cools with no hazmat damage by water or foam byproducts by creating a perfect solution for high-hazard applications and sensitive applications.”
This technology addresses the special requirements triggered by thermal runaway in Li-ion cells head-on. ELSA is a suppression system using ultra-cold, food-grade dry ice pellets to extinguish fires. Its genius is its simplicity and its cleanliness: a system of non-residue suppression, no water, no foam, no poisonous chemicals is required. It is thus very safe to use around breakable lithium batteries, breakable electronics, and other irreplaceable infrastructure. Its efficacy isn’t hypothetical; it’s been extensively tested and optimized on a lab bench and in actual deployment.
Aside from its current use in battery production, ELSA is creating a tremendous amount of buzz among recycling firms and engineers. In these instances, where fires within a battery can pose a significant threat to humanity and critical infrastructure, a system that can safely remove fires, with no gross smoke, no inundating workstations, and no soiling of gear, is priceless.
ELSA is a culmination of a 35+ year research and prototyping effort on dry ice fire suppression distilled into a time-proven, field-portable system. While energy storage systems are scaling up in mass across various industry applications, ELSA presents a distinct and sorely needed solution to combating one of the industry’s most perilous fire risks. Carver Fire is taking proactive steps to establish strategic partnerships across battery production, recycling, transportation, and research and development, broadening the scope of this award-winning technology.
