BESS Dual Agent Fusion Protection

Detect Earlier. Suppress Faster. Prevent Re-Ignition.

KFS BESS Dual Agent Fusion Protection brings together multiple layers of fire protection technology to address the progression of potential battery fire events.

REL-iON™ anomaly detection technology monitors conditions that may indicate developing battery instability, including temperature abnormalities, vibration, humidity, water leaks, refrigerant leaks, hydrogen, and volatile organic compounds (VOCs).

By identifying abnormal conditions early, these technologies provide opportunities for investigation and intervention before a potentially hazardous event escalates.

Advanced fire detection technologies provide additional monitoring for smoke and heat associated with developing fire conditions.

The solution incorporates detection technologies including ModuLaser® air sampling detection, spot smoke detection, and linear heat detection. When paired with AEGIS™-PHX and ARIES™-SLX control systems, these components support coordinated detection, alarm signaling, and suppression system response.

When abnormal battery conditions or a developing fire hazard are identified, the combined monitoring, detection, and control technologies support actionable warning and a coordinated response. REL-iON™ off-gas sensing works alongside smoke and heat detection, manual release and abort stations, and KiddeFenwal controls to help operators assess conditions and respond to emerging hazards.

Signals from the detection and control system can support mitigation measures through the Battery Management System (BMS), while integrated controls coordinate alarm and suppression functions. This layered approach helps facilities take action as conditions change, rather than relying on any single detection technology.

Dual-Agent Fire Suppression Technology

At the core of the solution is a dual-agent approach that combines rapid clean-agent suppression with extended inert-gas protection.

Fluoro-K™ Clean-Agent Fire Suppression

Fluoro-K™ provides rapid flame suppression to help control flaming combustion, reduce thermal loading, and limit the potential for fire propagation to adjacent battery modules.

Designed for fast response, the system delivers clean-agent discharge in under 10 seconds, helping protect sensitive electrical equipment and critical BESS infrastructure without leaving residue.

KiddeFenwal-sponsored testing demonstrated that rapid Fluoro-K™ deployment significantly reduced temperatures, suppressed flaming combustion, and helped prevent thermal runaway propagation throughout the tested battery pack.

NATURA™ IG-100 Inert-Gas Protection

Following initial suppression, hot battery cells and combustible gases may continue to present a risk of re-ignition.

NATURA™ IG-100 provides a second layer of protection by creating and maintaining an oxygen-reduced environment designed to inhibit re-ignition.

With positive pressure maintenance, extended inerting capability, and customizable hold times, NATURA™ IG-100 supports ongoing protection after the initial fire event.

By bringing these technologies together, KiddeFenwal provides a comprehensive solution designed to simplify the coordination of detection, suppression, and control systems for BESS applications.
