Emergency Cooling for Data Centers

Continuous cooling is critically important for data centers. In the event of a power outage or a failure of the cooling system, it can take 4 to 8 minutes for a conventional chiller to become operational again. In a data center, this amount of time is sufficient for servers to overheat, potentially leading to data loss — or, in the worst case, even fire.



With the HeatTank Intelligent Thermal Battery, this critical 4–8 minute gap can be bridged.

In the data centre under review, the key technical parameters are as follows:

  • Annual energy consumption for cooling: 266 000 kWh/year

  • Cooling demand: 180 kW

  • Cooling efficiency (EER): 2.93

  • Cooling temperature range: 10–18°C



The data centre requires 180 kW of power for emergency cooling. With a single HeatTank 50-1 Intelligent Thermal Battery, this demand can be covered for 20 minutes.

180 kWh * 20 min / 60 mins = 60 kWh


If the goal were energy savings instead of emergency cooling, using three Thermal Batteries would allow for a 27.1% reduction in the annual electricity consumption dedicated to cooling.


If both benefits are to be combined, then four Thermal Batteries would ensure both emergency cooling and significant energy savings.
