What is CRASH-CRESS™?
CRASH-CRESS™ is a high-performance containerised Battery Energy Storage System (BESS) developed by Tokai Engineering for mission-critical applications in Malaysia. Engineered on Lithium Iron Phosphate (LFP) chemistry with an advanced Energy Management System (EMS), it delivers instant backup power (<20ms), energy shifting to reduce electricity costs, and grid support for data centres, industrial facilities, and renewable energy projects. The system scales from 1 MWh to 100 MWh+ without redesign, and carries a 25-year design life.

How CRASH-CRESS™ Integrates With Your Infrastructure
How CRASH-CRESS™ Integrates With Your Infrastructure
CRASH-CRESS™ connects to your facility through a clean, modular architecture. The unit interfaces directly with the grid or utility supply, optionally with Solar PV generation, and communicates with your Building Management or SCADA system via the integrated EMS. The system operates autonomously — requiring no manual intervention for normal charge/discharge cycles — while providing full remote visibility and control.
For data centre deployments, CRASH-CRESS™ operates in parallel with existing UPS systems, providing extended runtime and seamless load transfer. For industrial applications, the EMS automatically identifies and executes peak-shaving opportunities based on your TNB tariff schedule.
- Grid / Utility connection with bi-directional metering
- Optional Solar PV integration (AC or DC coupled)
- EMS ↔ PMS / SCADA data exchange for facility-wide visibility
- Direct feed to data centre critical loads or factory distribution boards
Platform Capabilities
ALRAS System Components & Capabilities
Five core capabilities make CRASH-CRESS™ the right choice for operators who cannot afford downtime.
Millisecond-level response ensures uninterrupted power for critical loads. No warm-up time, no combustion — the battery is always charged and ready. Suitable for Tier III and Tier IV data centre uptime requirements.
LFP chemistry delivers high energy and power density in a compact containerised footprint, optimised for sites where space is at a premium. Minimal civil works required — arrives pre-assembled and factory-tested.
Designed for tight integration with solar PV systems — capturing excess renewable generation and deploying it at times of highest value. Directly supports Scope 2 emissions reduction and Malaysia's Net Zero 2050 commitments.
The embedded Energy Management System provides real-time monitoring, predictive maintenance alerts, charge/discharge optimisation against tariff schedules, and full remote diagnostics — accessible via web dashboard or SCADA integration.
Multi-layer protection combining LFP's inherently stable chemistry with integrated fire suppression systems and active thermal management. Compliant with NFPA 855 installation requirements and UL 9540A fire safety testing.
Start with the capacity you need today and add modules as your demand grows — without changing the core system architecture. CRASH-CRESS™ scales from a 1 MWh edge deployment to 100 MWh+ hyperscale configurations.

- Black start and grid support for full site recovery after outages
- Business continuity and disaster recovery — eliminate single points of failure
International Standard for Lightning Protection
The 2024 edition of IEC 62305 (Protection Against Lightning) is the foundational lightning safety standard. It now formally incorporates risk to people in open areas and recognises IEC 62793-compliant LWS as an important preventive protection measure — a significant new requirement for construction and industrial sites.
Thunderstorm Warning System Standard
IEC 62793 defines performance requirements, detection thresholds, warning output criteria, and installation requirements for Thunderstorm Warning Systems (TWS/LWS). It specifies how a system must behave across detection, advisory, warning, and all-clear phases to be considered compliant. The ALRAS system is designed to meet IEC 62793 operating concepts.
Occupational Health & Safety Compliance
ISO 45001 requires organisations to identify and systematically control occupational hazards, including lightning for outdoor workers. The OSHA Malaysia (Occupational Safety and Health Act 1994) places duty-of-care obligations on employers and contractors. An LWS with documented event logging provides auditable evidence of a systematic lightning risk control measure.

FAQ
Frequently Asked Questions
Common questions about Lightning Warning Systems, IEC 62793, compliance requirements, and the ALRAS system from Tokai Engineering.
Need LWS advice specific to your project in Johor Bahru, Selangor, or elsewhere in Malaysia?
What is a Lightning Warning System (LWS)?
For certain building classes — including high-rise buildings, government structures, and facilities storing hazardous materials — LPS installation is required under JKR specifications and local authority requirements. For other buildings, an IEC 62305-2 risk assessment formally determines whether an LPS is warranted. Tokai can conduct this assessment and provide a stamped engineering report.
Is a Lightning Warning System required under IEC 62305:2024?
The IEC 62305:2024 edition formally addresses protection of people in open areas as part of lightning risk management, and recognises IEC 62793-compliant LWS as an important preventive measure. For hyperscale data centre construction in Johor Bahru and Selangor, an LWS is increasingly required by international consultants, main contractors, and OSHA compliance frameworks — particularly where thousands of outdoor workers are exposed daily.
What is IEC 62793?
IEC 62793 is the international standard for Thunderstorm Warning Systems (TWS), also known as Lightning Warning Systems (LWS). It defines performance requirements, detection methodologies, warning thresholds, and installation criteria for systems designed to protect people in open areas from lightning risk. A system aligned with IEC 62793 is formally recognised by IEC 62305:2024 as a valid preventive protection measure.
What is the difference between an LWS and an LPS?
A Lightning Protection System (LPS) protects the building from direct strikes — air terminals, down conductors, and earthing intercept the strike and conduct it safely to ground. A Lightning Warning System (LWS) protects people in open areas — it detects the approaching storm and triggers an evacuation before anyone is struck. Both are required for complete lightning safety under IEC 62305:2024.
Does Tokai provide LWS in Johor Bahru?
Yes. Tokai Engineering provides ALRAS Lightning Warning System supply, installation, testing, commissioning, and maintenance across all of Johor — including Johor Bahru, Iskandar Puteri, Senai, Kulai, and the Sedenak Tech Park corridor. We are actively supporting hyperscale data centre construction and large-scale industrial projects throughout the Johor digital infrastructure zone. We also serve Kuala Lumpur, Selangor, Penang, Perak, and all states nationwide.
How does the ALRAS LWS support ISO 45001 and OSHA compliance?
ISO 45001 requires organisations to identify and control occupational hazards — including lightning for outdoor workers. The ALRAS LWS provides documented, timestamped event logs for every alert and all-clear, exportable as evidence of a systematic lightning risk control measure. This supports OSHA Malaysia (OSH Act 1994) duty-of-care obligations and helps contractors demonstrate compliance during audits and investigations. An LWS is increasingly required in site safety plans for hyperscale data centre and infrastructure projects in Malaysia.
Can the ALRAS LWS be installed on a temporary construction site?
Yes. The ALRAS system is specifically designed for rapid deployment on temporary construction sites — solar-powered, wireless, requiring minimal civil works. It can be mobilised quickly for a new site and relocated or extended as the construction programme progresses. Tokai advises on the optimal configuration for your site footprint and provides maintenance support throughout the project duration.
