Our unique Gravi2Cool™ closed-loop system uses an electric vacuum pump—powered by Gravi2Power™—to create a vacuum that evaporates liquid water. This process generates slurry ice, which further condenses the evaporated water back into liquid form for recycling, without the need for makeup water or additional energy. Remarkably, and unlike typical systems, it does not generate heat and therefore is not an electric heater (liquid → evaporation → ice → condensation → liquid).
Data Center Case
Forecasts are bleak: by 2030, consumption could reach up to 13% of global power consumption. This increase is mainly due to the growing demand for digital services and the increase in the amount of data generated. Hyperscale data centres, which are huge facilities, are seeing their consumption grow even faster. Demand could increase by 35% a year until 2040.
Data center energy efficiency is . Improving efficiency reduces operational costs, environmental impact, and reliance on energy grids. Key metrics like Power Usage Effectiveness (PUE) are used to quantify efficiency, and strategies range from optimizing IT equipment and cooling systems to leveraging renewable energy and waste heat reuse.
Power Usage Effectiveness (PUE) is the industry standard metric for measuring data center energy efficiency. PUE is calculated by dividing the total energy used by the data center facility by the energy used by the IT equipment (servers, storage, etc.).
Electricity costs are one of the largest ongoing expenses for data centers. Cooling systems: (40-54% of total power) essential to dissipate the immense heat generated by IT equipment and maintain optimal operating temperatures. For them, effective and secured power and water management is not just an environmental concern, but a fundamental business imperative that impacts costs, operational stability, and brand reputation.
Data center energy efficiency involves optimizing various aspects of the data center’s design and operation, including cooling systems, ventilation, power usage, and hardware selection. Measuring and improving energy efficiency is crucial for reducing operational costs, minimizing environmental impact, and ensuring the long-term sustainability of data centers.
Unique LatentHeatPump™ Benefits Data Centers – up to 5°C passive cooling
Latent Heat Pump™ is a unique enthalpy recovery ventilator and a dehumidifier in warm ambient. Its performance is better the warmer and more humid the outdoor air is. It has up to up to 5°C passive cooling without additional energy reducing cooling costs up to 80 %.
The optimal temperature in data centers typically ranges from 68°F to 72°F (20°C to 22°C). This range helps ensure that servers and other equipment operate efficiently while minimizing the risk of overheating. Maintaining proper humidity levels is also important, usually between 45% and 60%, to prevent static electricity and condensation issues.
Gravi2Cool™ Benefits:
- Low PUE Enables High Profitability
- Power Generation Does Not Need Additional Energy Supply
- Condensation by Slurry Ice
The evaporated water vapor is condensed back into liquid water by slurry ice itself.
- Water Recycling, No Makeupwater
- Because the condensation process is part of the closed system, the condensed water can be used again, eliminating the need for a supply of fresh water.
- No Heat Rejection
Unlike typical compressor-based cooling systems that require heat exchangers to release heat into the environment, this system’s cooling process relies on phase change (liquid to slurry and gas, then back to liquid) within a closed loop, thus not requiring heat rejection.
