Who We Are

Southern Knight Fire Tek is redefining lithium-ion battery fire safety with the world’s only all-natural solutions engineered to eliminate thermal runaway.

Traditional methods focus only on cooling — we go further by neutralizing chemical reactions, encapsulating toxic gases, and preventing reignition.

Our patent-pending products — Thermal Stop and Thermal Shield — are trusted by first responders and industries across the globe. From small devices to electric vehicles and large-scale energy storage systems, we deliver fast, safe, and sustainable protection when seconds matter most for any class of fire.

At Southern Knight Fire Tek, our mission is simple: protect people, property, and the planet with next-generation fire suppression technology built for today’s energy-driven world.

Commitment to Innovation and Safety

Every product we create is driven by our commitment to innovation, environmental responsibility, and real-world performance. By replacing traditional chemical foams and PFAS-heavy suppressants, Southern Knight Fire Tek is leading the way toward a cleaner, safer future in fire suppression.

Our Most Popular Products

Thermal Stop- Extinguisher Fires Fast

Thermal Stop is the only extinguishing agent purpose-built to stop thermal runaway in lithium-ion batteries. Instead of relying on prolonged cooling, it penetrates deep into compromised cells to halt the chain reaction in as little as 30 seconds.

  • All-natural & non-hazardous

  • Certified to NFPA 18 standards

  • Rapid endothermic cooling

  • Chemical disruption at the source

  • PFAS encapsulation for safe containment

Easy to deploy and quick to clean, Thermal Stop sets a new standard for lithium-ion fire suppression with its patent-pending design — engineered for speed, safety, and sustainability.

Thermal Shield- Prevents Reignition

After flames are out, the danger isn’t gone. Thermal Shield is the only gel suppressant proven to prevent reignition during transport and storage of damaged battery systems.

  • Instant surface cooling

  • Seals breaches to stop chemical activity

  • Encapsulates hazardous PFAS vapors

  • All-natural, NFPA 18 certified formula

  • Easy cleanup and minimal application

Thermal Shield keeps compromised batteries stable, secure, and under control until they can be safely repaired or disposed of — giving professionals peace of mind when it matters most.
