Separation between units, rooms and risk areas
DURASTEEL® fire-resistant and impact-resistant walls
Protecting critical equipment and maintaining functional continuity
Why is passive fire protection required?
Energy storage systems concentrate a lot of energy in a small area. A failure in a cell or module may develop into a thermal runaway, releasing heat, flames and exhaust gases and spreading between adjacent units. Electrical failures, overheating, arcing and, in some systems, ignition of insulating liquids may occur in transformer rooms.
Passive fire protection is designed to create a permanent physical separation between units, rooms and risk areas. Its purpose is to limit the passage of fire, heat, smoke and combustion gases, reduce exposure of adjacent units and prevent, as much as possible, a local event from developing into a widespread system failure.
Compartmentation is particularly important for protecting control systems, electrical panels, cables, transformers and auxiliary equipment, and for maintaining functional continuity of the parts of the premises that have not been damaged.
The design, production and installation process
1
Risk survey and planning data
Collecting system data, failure scenarios, fire and page loads, and the requirements of the certifying authority
2
Mapping nearby units and equipment
Identification of storage units, transformers, panels, cables, control systems and equipment that need to be protected
3
Setting performance goals
Determining fire ratings, stability, integrity, insulation and fire protection requirements according to the project
4
DURASTEEL® System Design
The engineering of the walls, the supporting construction, the anchors and connections to the structure
5
Design of openings and penetrations
Integrating doors, cable and pipe passages, ducts and seams in a complete and continuous system
6
Production and installation
Manufacturing the system components and installing them on site according to the design, specifications and manufacturer's information
7
Control, documentation and delivery
Quality checks, documentation of exceptions, evidence of execution and preparation of As Made documents according to project requirements
Adapting the system to the risk scenario
The design is determined by the type of storage system or transformer, failure scenarios, available fire test data, distances between units, fire and thrust loads, adjacent equipment, access routes, and requirements of the competent authority. The separation is considered as a complete system that includes walls, connections, openings, doors, penetrations, and interfaces with building systems.
System continuity, installation and quality control
The performance of the compartmentation depends on the continuity of the system and not only on the panel itself. The connections to the construction, the junctions between elements, the seams, the openings and the penetrations of the cables and pipes must be designed and executed in accordance with approved system details. The control includes checking the suitability of the materials, the quality of the installation, the documentation of exceptions and the preparation of execution and committee documents.

Frequently Asked Questions
Active and passive protection systems complement each other. Passive separation is permanently present and does not depend on activation, and is designed to limit the spread of an incident between units and areas.
An appropriate separation wall limits the passage of flame and reduces the thermal exposure of adjacent units. The design is determined by the layout of the complex, the fire scenario, the distances and the required performance objectives.
Yes, subject to suitability for the transformer type, insulation materials, fire load, failure scenarios and project requirements. The design may include separation between transformers and between the transformer room and adjacent critical equipment.
DURASTEEL® is a non-combustible composite panel manufactured by Promat, with a reinforced cementitious core and perforated steel cladding, used in fire, impact and impact resistant systems.
Already in the early planning stage, before the layout of the units, openings and system passages is fixed. This way, compartmentalization requirements can be incorporated into the structure and changes can be minimized during the execution stage.
