Description
Battery Energy Storage System (BESS) for Hazardous and Non-Hazardous Areas
EK Engineering develops industrial-grade BESS solutions engineered for deployment at both hazardous and non-hazardous environments, with system architecture, safety philosophy, and compliance scope defined on a project-requirement basis according to international standards.

BESS for Hazardous Areas (Zone 1 & Zone 2)
Hazardous area certified BESS units are engineered for locations where flammable gases, vapours, or combustible dust may be present under normal or abnormal operating conditions.
System design addresses ignition prevention, energy containment, and controlled operation through certified equipment and protective measures.
Design considerations include:
- Compliance with ATEX / IECEx area classification requirements
- Explosion-proof or pressurised enclosures with purge and monitoring systems
- Certified electrical and control components
- Integrated gas detection and fire mitigation systems
- Controlled ventilation and thermal management
Typical applications:
Oil & gas facilities
Refineries and petrochemical plants
Chemical and process industries
Mining and bulk material handling installations
BESS for Non-Hazardous Areas
For non-hazardous environments, BESS systems are designed to optimise performance, scalability, and lifecycle efficiency while maintaining a high level of operational safety. These systems are commonly deployed in grid-connected, renewable, and industrial power applications.
Design considerations include:
- Industrial or outdoor-rated containerised enclosures
- High-efficiency power conversion and energy management systems
- Air-cooled or liquid-cooled thermal management
- Optimised layout for installation, access, and maintenance
Typical applications:
- Utility-scale energy storage
- Renewable energy plants (solar and wind)
- Microgrids and off-grid power systems
- Data centres and critical infrastructure
- Commercial and industrial facilities
System Architecture and Functional Scope
BESS solutions are developed as integrated systems comprising electrical, mechanical, control, and safety subsystems.
Key architectural elements include:
- Modular energy storage capacity from 50 kWh to 1000 kWh

- Electrical system design and protection coordination
- Enclosure and thermal management engineering
- Fire detection and mitigation strategy
- Integration with site electrical systems and control platforms
- Documentation to support installation, operation, and compliance
Frequently Asked Questions (FAQ)
What makes a BESS suitable for hazardous areas?
Hazardous area BESS systems use explosion-proof or pressurised enclosures, certified components, gas detection, and fire suppression systems to prevent ignition in flammable environments.
Can the same BESS platform be used for hazardous and non-hazardous areas?
Yes. The core BESS architecture is modular and can be configured with different enclosures, certifications, and safety systems depending on site classification.
Is this BESS suitable for global deployment?
Yes. Systems are engineered to comply with international standards and can be localized to meet country-specific regulatory requirements.
What capacity ranges are available?
We offer BESS solutions from small commercial systems to large multi-kilowatt utility-scale installations.
