BESSY

BESSY is a fire separation system developed specifically to address fire separation requirements within battery energy storage system layouts. The system is configured to separate battery units, rooms, or zones using passive fire-rated assemblies.

BESSY

Fire separation systems for battery energy storage layouts

BESSY provides passive fire separation within battery energy storage system installations. The system is designed to help compartmentalize layouts and limit fire spread between battery units, rooms or zones.

System overview:

BESSY systems are configured using fire-resistant barrier assemblies designed to integrate into common BESS layouts. Assemblies can be adapted to support different spacing, enclosure, and separation requirements based on project configuration.

Introducing the three levels of fire protection now available with the BESSY system:

BESSY SF
Our most tried and tested system offers stability and integrity for 6 hours, along with simplicity in installation and removal. BESSY SF is a modified version of our highly successful DuraBarrier SF, used for exterior transformer fire separation.

BESSY 120
This 2-hour fire rated barrier is based on our UL/ULC listed non-load bearing wall. Interlocking tongue and groove joints allow BESSY 120 to be easily installed and removed.

BESSY 240
Based on our UL/ULC 4-hour listed fire barrier, BESSY 240 is perfect for applications requiring greater thermal protection where space is limited. The modular design provides superior fire resistance while allowing simple installation and removal.

Typical applications include:

  • Separation between battery units or racks

  • Fire-rated divisions within BESS rooms

  • Containerized or building-based BESS layouts

  • New installations and retrofits

FAQ

Customers frequently ask.

What is the BESSY system used for?
Arrow

BESSY is an engineered passive fire barrier system used to help control the spread of fire and associated elevated temperatures between battery energy storage units. It supports defined separation distances and provides reliable fire separation in utility, commercial, and industrial energy storage projects.

What testing and certifications support BESSY?
Arrow

BESSY is supported by testing to UL/ULC and ASTM standards. Listings and documentation are available to assist with engineering review, permitting, and specification requirements.

How do I know which BESSY configuration I need?
Arrow

Configuration depends on separation distance, site layout, exposure conditions, and project requirements. Our engineering team reviews these factors and recommends the most appropriate BESSY configuration for each application.

Can BESSY be used on existing sites or only new projects?
Arrow

BESSY can support both new installations and retrofits on existing sites, subject to available space, foundations, and access. We work with project teams to evaluate feasibility and integration options in each case.

What information do you need to provide a quote or specification?
Arrow

Typical information includes site drawings or sketches, equipment spacing, desired separation performance, local code considerations, and any structural or foundation constraints. The more detail you can share, the more precise our recommendations will be.

Do you provide engineering support during installation?
Arrow

Yes. We provide technical guidance, documentation, and clarification during installation to help ensure BESSY is installed as designed and performs as intended in field conditions.
