Ohmitron’s 4 MWh Immersion-Cooled BESS delivers safety, efficiency, and compactness in a 20-ft container. It uses dielectric immersion cooling for superior fire resistance, extended lifespan, and enhanced grid flexibility. Designed for outdoor deployment, it supports the demanding energy needs of modern data centers and edge facilities. A 40-ft container version expands this capability with integrated immersion-cooled infrastructure specifically tailored for data center applications. The system includes pre-configured racks, power distribution, cabling, monitoring, fire suppression, and security. Its advanced architecture ensures exceptional thermal performance using eco-friendly coolant. Engineered for durability, it withstands seismic activity, dust, wind, and water for reliable operation in harsh environments.
Each battery module is immersed in dielectric fluid (S5X) for optimal thermal control and fire safety.
Smoke/H₂ detection, inert cooling fluid, and emergency shutdown ensure safety per UL 9540A and IEC standards.
Distributed BMS with SOC/SOH tracking, touchscreen HMI, and remote SCADA/cloud integration.
Delivers 4 MWh in a compact IP65-rated 20-ft container with IP67 module enclosures.
