Our Patented Technology

Nautilus Data Technologies created the world’s most innovative water-cooled data center design, setting a new standard for energy efficiency, environmental sustainability, and global scalability.

Zero Impact Cooling System

Our patented Total Resource Usage Effectiveness (TRUE) cooling closed water loop technology allows us to use nature’s cold water to keep racks cool. The system integrates proven maritime and industrial water-cooling technologies with next generation data center infrastructure to mark a new era of performance for the data center industry.

No Threat of Water

The system is under vacuum – water can't escape and create any risk to IT load. Open a valve or break a hose? Air is sucked in; it doesn’t leak water out.

Zero Water Consumption

We do not use any drinking water or produce any wastewater. We use zero refrigerants, zero chemicals, and cause no harm to the water or wildlife.

Competitive Rates

With first in class PUE, customers save money on their metered cost of energy, with associated reductions in carbon emissions and air pollution.

How the Water-Cooling System Works

Water is capable of absorbing more heat at a faster rate, 3,500 times faster, than an equivalent mass of air or mineral oil. Our closed loop and open loop water system is a superior form of cooling IT in the most sustainable way possible.

Closed Loop System

It's here where the closed loop of pure cool water is able to absorb the heat generated by the IT gear via immersion, direct-to-chip, overhead coil, or rear door exchange. The warm water goes back to the heat exchanger to be cooled back down and cycled back through the data center.

Open Loop System

Our patented water cooling technology can intake cool water from any type of water body: lake, river, or ocean. From the large drum intake, the water travels through a multi-step, multi-element filtration process that causes zero harm to wildlife with no chemical additives. The coolness of the water is brought into the heat plate exchanger to cool the water from the closed loop system. When complete, the water is returned to the source with only a minimal increase in temperature.

Environmentally Friendly

The data center operates at the highest level of energy efficiency, with no water consumption, no refrigerants, no water treatment chemicals, no wastewater, and no harm to wildlife.

Frequently Asked Questions

Most frequent questions and answers

About Nautilus Data Technologies

A Nautilus Data Technologies data center is an ultra-high efficiency facility cooled by natural water resulting in the lowest validated Power Utilization Effectiveness (PUE) in the industry. The Nautilus water-cooled data center has the flexibility of being constructed on a vessel or on land near a body of water.
Cost Savings: Nautilus offers a lower cost for consumers through high density rack spaces, energy and resource efficient cooling systems, and reduced construction time. Efficiency: The Nautilus water-cooled data center design has the lowest validated Power Utilization Effectiveness (PUE) of any commercial data center, reducing carbon emissions and energy usage by up to 30%. Simplified System: The Nautilus data center design strips away complexity, points of failure and polluting elements of the traditional data center design to focus on the essential bottle-neck: cooling. Because the Nautilus data center is deployed on or near water, this accessibility directly cools the heat at the source, without evaporating or consuming any potable water nor water treatment chemicals. Decreased Build Time: A manufactured Nautilus water-cooled data center is constructed and deployed in approximately nine to twelve months across the globe, compared to much longer build cycle for traditional, land-based air-cooled data centers. Resilient Facility: A Nautilus facility is highly secure and disaster resilient, making them ideal for earthquake, flood or other disaster-prone areas. Additionally, similar to traditional air-cooled data centers, Nautilus seeks to deploy in disaster-free zones.

Nautilus Data Center Technology

Nautilus data centers have a guaranteed estimated PUE of 1.15 globally, in most locations.
PUE is a common global metric used to determine data center energy efficiency. PUE is the ratio of energy used to run IT and IT supporting equipment, such as cooling and power systems, compared to the energy to run only the IT equipment.
Water-cooling is a form of convection cooling utilizing the high heat transfer capabilities and thermal capacity of water. Water is capable of absorbing more heat at a faster rate, 3,500 times faster, than an equivalent mass of air or mineral oil.
Nautilus data centers are technically and environmentally engineered to be optimized for specific salinity and water conditions. Nautilus facilities are engineered with corrosion resistant materials.
Nautilus systems are capable of cooling up to 105 kW per rack.
Nautilus data centers are designed for uninterrupted power and connectivity during server technology upgrades or maintenance.
Nautilus data centers are designed to be deployed on or near a body of water to take advantage of Nautilus’s patented water-cooling technology for maximum cooling. Bodies of water may include ports, lakes, rivers, canals, harbors, or protected ocean bays.
Each Nautilus water-cooled data center is housed within a water-proof, dust proof facility with NEMA 3 rating, F3 tornado rating, and F3 hurricane rating. Internally, the facility has an extensive monitoring and leak prevention system (LPS) for all piping. The Nautilus facility is highly secure and disaster resilient.

Nautilus Water-Based Data Centers

Nautilus floating data centers are deployed on International Maritime Organization (IMO) certified barges to optimize access to intake water sources for advanced water-cooling processes. Vessels are proven naval structures that offer durability, mobility, stability, reliability, disaster resilience, and an economic alternative to scarce and expensive land.

A land-based data center is a facility built in its permanent location, on land, with all IT equipment housed within that facility.

A water-based data center is a facility based on a vessel with all IT equipment housed within. A waterborne data center can be transported to a different location after construction.

Nautilus water-cooled data centers are water agnostic and do not require or use potable water. Nautilus facilities are designed to intake a multitude of water types and conditions (salt, brackish, grey, fresh, or potable water) and return the water back to its original source with negligible thermal impact. No water treatment chemicals are added to the water during the cooling process.
A water agnostic system is capable of operating in any water and is resistant to damages caused by particulate within impure water. A water agnostic system could run with drinking, brackish, salt, or grey water.

The sizing of the data center varies based upon configuration and customer requirements. The current 6 MW data center vessel is 230 ft long and 55 ft wide.
