Guardian Indoor
Patented Immersion Cooling

Patented Immersion Technology

Battery cells are submerged in non-toxic dielectric oil for direct active thermal management, fire suppression, and propagation prevention.

Active Thermal Management

Efficient Thermal Management

Submerging battery cells in our dielectric liquid prevents hot spots and allows the cells to consistently run at optimal temperatures.

Integrated BMS EMS

Integrated BMS & EMS

Our non-Chinese BMS and EMS ensure optimal performance, safety, and efficiency, offering unmatched reliability and control.

Battery Immersion Cooling Fire Suppression

Enhanced Fire Suppression

Our immersion fluid immediately cools and extinguishes any flames, ensuring enhanced safety and propagation prevention.
