Cooling system for energy storage units and containers, 70 kW
A 70 kW air cooling unit for cooling energy storage units and containers. Maintains the optimal temperature of components to extend their lifespan and ensure reliable performance.

Operating environments
This system is intended for applications where:
-
the thermal load is high and continuous
-
the system operates 24/7
-
cooling failure would result in significant financial or safety risks
-
an industrial-scale solution is required rather than conventional air conditioning
Typical applications include:
-
large energy storage systems (BESS)
-
battery and inverter containers
-
grid support solutions
-
industrial technical rooms and containers
