3B BessaShield™ System
The BessaShield™ system is a fully integrated, multi‑hazard protection solution engineered specifically for the complex and escalating risks associated with Battery Energy Storage Systems (BESS). Unlike traditional approaches that address individual threats in isolation, BessaShield™ is designed to perform as a unified system—simultaneously defending against extreme fire exposure, blast overpressure, fragmentation, ballistic impact, and forced entry. It is purpose‑built to withstand the full progression of a real‑world BESS event, from initial thermal runaway through prolonged high‑temperature exposure and potential explosive failure, while maintaining structural integrity and containment.
Built on proven, real‑world testing and engineered for constructability, BessaShield™ delivers consistent performance across walls, gates, openings, and access points—eliminating weak links common in conventional protection systems. Its modular design allows for flexible configuration to suit new installations, retrofits, and constrained or live operational sites, while supporting fast, efficient installation. Delivered as a turnkey solution, BessaShield™ reduces project risk, enhances life safety, protects high‑value assets, and provides long‑term resilience for critical energy infrastructure in an increasingly demanding regulatory and operational environment.
BessaShield™ – Key Features
Fully Integrated Multi‑Hazard Protection
BessaShield™ is engineered as a single, cohesive system that addresses the full spectrum of BESS risks concurrently—fire, blast, fragmentation, ballistic impact, and forced entry. Unlike traditional solutions that layer independent products together, BessaShield™ is designed holistically to perform under complex, cascading event scenarios, eliminating gaps and incompatibilities between systems.
Extended‑Duration Extreme Fire Resistance
The system is purpose‑built to manage prolonged, high‑energy thermal events associated with lithium‑ion battery failures.
- Tested to withstand up to six hours of continuous fire exposure
- Maintains structural integrity at temperatures exceeding 2,000°F (≈1,100°C+)
- Successfully resists post‑fire hose‑stream impact, ensuring durability after suppression
- Designed to provide critical time for evacuation, emergency response, and event control (8‑hour fire certification in progress)
Blast Overpressure & Fragmentation Mitigation
BessaShield™ is engineered to contain and mitigate blast effects caused by rapid pressure buildup and explosive failure conditions.
- Reduces transmitted blast overpressure to adjacent units and critical infrastructure
- Controls secondary fragmentation that can otherwise propagate damage
- Helps prevent cascading failures across densely arranged BESS installations
- Protects both internal assets and surrounding site infrastructure
Inherent Ballistic Protection
Ballistic resistance is built directly into the core structural design—not applied as an add‑on.
- Multi‑hit ballistic capability validated through sustained testing
- Maintains protection under repeated impacts from multiple weapon types and calibers
- Ensures consistent performance even during prolonged or escalating security incidents
Forced‑Entry Delay and Denial
BessaShield™ provides robust physical security against unauthorized access and deliberate attack.
- Engineered to resist aggressive, sustained forced‑entry attempts
- Delays intrusion long enough to enable response and intervention
- Enhances site security during both normal operations and emergency conditions
- Supports compliance with critical infrastructure protection requirements
Modular, Scalable System Architecture
The system’s modular design supports a wide range of BESS configurations and project requirements.
- Easily scalable for small, large, or utility‑scale installations
- Adaptable for new construction, retrofits, and system expansions
- Compatible with tight, congested, or irregular site layouts
- Suitable for installation in live operational environments
Turnkey Engineering & Delivery
BessaShield™ is delivered as a complete, end‑to‑end solution with a single point of accountability.
- Engineering and system design
- Structural calculations and PE‑stamped drawings
- Manufacturing, logistics, and delivery
- Installation, QA, and final verification This approach simplifies project coordination, reduces risk, and accelerates deployment schedules.
Real‑World Validated Performance
The system is tested and validated using realistic, multi‑hazard testing protocols rather than isolated laboratory assumptions.
- Reflects true BESS failure sequences and threat environments
- Aligns performance expectations with insurer, regulator, and operator requirements
- Provides confidence in system behavior under extreme, compounded conditions
Efficient Installation with Minimal Disruption
BessaShield™ is designed with constructability and operational continuity in mind.
- Modular components enable efficient sequencing and rapid installation
- Minimizes interruption to ongoing site operations
- Reduces downtime and associated financial impact
- Supports accelerated project schedules without compromising performance
