Application
Battery Energy Storage Systems
Battery energy storage installations require separation between battery units, rooms, and zones to limit fire spread and support system resilience. DuraSystems provides passive fire separation systems configured specifically for common BESS layouts, including containerized and building-based installations. Systems are designed to integrate into new installations and retrofit projects while accommodating spacing, access, and layout requirements typical of energy storage facilities.

Overview
Battery energy storage systems concentrate large amounts of energy within compact footprints, making layout and separation critical considerations. Fire separation systems are used to compartmentalize battery units, limit escalation between zones, and support safer facility layouts.
DuraSystems products are used to create passive fire separation within energy storage installations without introducing active systems or operational complexity.
Typical system considerations
Containerized versus building-based layouts
Separation between battery units or racks
Clearances for access and maintenance
Retrofit and/or new installations
About Application
Common configurations
Fire separation systems are installed between battery units, racks, or rooms to define clear separation zones. Assemblies can be configured to align with project layouts, spacing requirements, and enclosure types while maintaining consistent separation performance.
