Maximum Operational Security When It Matters Most

Whether it's a data centre, a hospital surgery room, or an industrial production line, operational reliability is non-negotiable. In the event of a power outage or cooling system failure, it can take 4 to 8 minutes for conventional chillers to restart — a delay that can be critical. Thanks to the innovative technology of the HeatTank Thermal Battery, this vulnerable window can be effectively bridged, ensuring uninterrupted operation even while other systems are still rebooting.

In comfort cooling applications — such as office buildings — recovery times can be even longer. Emergency protocols are often lacking, and restarting the system may require service personnel to intervene. In such cases, HeatTank plays a vital role by temporarily maintaining the desired indoor temperature, helping avoid discomfort and tenant complaints.

To determine the duration of safety cooling, it is important to define the objective. It is necessary to find the capacity that ensures sufficient cooling for the required period.

If the cooling demand is 60 kW, it can provide cooling for 1 hour
(60 kWh / 60 kW = 1 h).
If the cooling demand is 120 kW, it can provide cooling for 0.5 hours
(60 kWh / 120 kW = 0.5 h).
If the cooling demand is 30 kW, it can provide cooling for 2 hours
(60 kWh / 30 kW = 2 h).

The diagram below shows how long a single HeatTank 50-1 Thermal Battery can independently meet cooling demands, depending on the required power output.

Of course, there is no upper limit here either—longer cooling durations and higher power demands can be met using multiple Thermal Batteries.

HeatTank’s heat loss is a maximum of 1–2% per day, so it is recommended to recharge it at least once a week to compensate for this loss. This ensures that the Thermal Battery remains above 90% charge and is able to provide cooling for an adequate period in case of an emergency. Of course, heat loss can also be recharged daily, in which case the 1–2% daily loss is compensated on a daily basis.

The Intelligent Thermal Battery Control System automatically handles recharging, as well as activation in the event of a failure.

Don’t let an unexpected cooling outage put your data, surgeries, or tenant satisfaction at risk. HeatTank – the reliable backup when it matters most.
