Data Centres

Thermal Box ensures efficient cooling in data centres

Are you running a data centre?

There’s no doubt that data centres are at the heart of digital infrastructure. Cooling undoubtedly makes up a significant part of energy costs, and on the hottest days, maintaining a stable temperature without exceeding the power grid’s capacity can be challenging. Additionally, operational costs rise significantly when electricity is at its most expensive.

We have a solution that makes cooling smarter through thermal energy storage: the Thermal Box. It ensures that your data centre can maintain a stable temperature without unnecessary energy spikes – reducing both energy consumption and operating costs.

Thermal Box delivers energy-efficient cooling

The Thermal Box provides data centres with a more efficient and cost-effective way to manage cooling. Instead of oversizing systems to meet maximum demand, we help you store cooling energy when energy prices are low. The stored cold is then used on hot days when energy demand is at its peak.

Technically, the Thermal Box uses phase change materials (PCM) to store large amounts of cooling energy when temperatures drop below a certain threshold. Once the energy is stored, it’s released throughout the day. This allows the cooling system to operate closer to optimal performance.

What Thermal Box does for you

  • Load Shifting: Move your energy usage to times with lower prices, reducing strain on the power grid and cutting energy costs.
  • Peak Shaving: By using stored cooling energy when demand is highest, you reduce the need to draw a lot of power during the most expensive periods.
  • Optimal Operation: The system enables your cooling plant to operate under more stable conditions. This increases energy efficiency and prevents oversizing of the cooling system.

Advantages of Thermal Box in data centres

  • Stable cooling throughout the day: Your data centre enjoys consistent temperature control without the cooling system running at full capacity. This reduces wear and tear on the systems and extends the life of the equipment.
  • Backup function: If the main cooling system fails, the Thermal Box acts as a safeguard. It keeps operations running, preventing damaging overheating in the data centre.
  • Reduced Costs: By using cheaper electricity for cooling at night and utilising that cold during the day, you reduce operational costs and avoid investing in oversized cooling systems.

Why choose Thermal Box from Cartesian?

By installing the Thermal Box, you gain a smarter and more sustainable solution for data centre cooling. Our technology optimises your cooling system so it can be tailored to average rather than maximum loads. Plus, you get a flexible system that adapts to different operating conditions – without needing to replace the entire plant. This results in lower investment costs.

✔️ Full control over energy usage

The Thermal Box also provides more precise energy management, allowing you to monitor and adjust your cooling system’s performance in real-time. This gives you better control over energy usage and makes it easier to optimise cooling efficiency, ultimately reducing energy waste.

✔️ Extends the life of the cooling system

In addition to reducing the load on the power grid, the Thermal Box helps extend the life of your existing cooling systems. It prevents equipment from being overworked during periods of high demand, resulting in fewer repairs and less need for maintenance. This will also lead to long-term savings.

✔️ Reduces carbon emissions

For data centres working towards strict ESG targets (Environmental, Social, and Governance), our solution is a valuable tool for reducing carbon emissions. The Thermal Box helps you use energy more efficiently and cut energy consumption during periods with a high CO2 footprint.
