Slash energy peaks, extend equipment life, and stay ahead of rising operating costs—without a full system overhaul.
Data centers today fall into four main categories:
All four types are facing a rapid surge in electricity demand — projected to jump from roughly 20 TWh per year in 2024 to over 30 TWh per year by 2030.
Most legacy sites rely on wet cooling towers, dry coolers or adiabatic air-cooling. These systems are pushed hardest—and become least efficient—when outside temperatures peak.
The result? higher energy bills, increased carbon emissions and elevated risk of thermal hotspots exactly when reliability matters most.
Peak / time shifting can save up to 50% of the electricity and water consumption for cooling. At the same time, operating and maintenance costs are reduced by up to 20%.
This not only improves the PUE and WUE of the data center, but also achieves an ROI of approx. 5 years.
During off-peak periods—e.g. 20 °C ambient at night—standard chillers often operate at just 20 % capacity. To maintain temperature, the compressor “hunts” by cycling on and off, which drives up energy consumption and accelerates component wear.
By charging HeatTanks when demand is low and discharging as load increases, we raise the chiller’s effective load from 20 % to 40 %. This moves the system into its optimal operating range and delivers a 49 % increase in EER, reducing energy use and extending compressor life.
During daytime peaks—say, 35 °C ambient temperature and a full cooling load—discharging our HeatTanks immediately reduces the chiller’s effective load from 100 % down to 85 %. This shift moves the system into its optimal operating point and yields an EER increase of 31 %.
Conventional chillers with fixed compressor stages often struggle with part-load conditions: the compressor continually hops between discrete capacity steps, wasting energy and causing wear. By smoothing the load profile with thermal storage, our solution eliminates these frequent stage changes and delivers both greater efficiency and increased equipment longevity.
| 25 – 50 % | less cooling energy |
| ≤ 40 % | peak load reduction |
| ≤ 35 % | lower water consumption |
| ~ 20 % | savings in OPEX + maintenance |
