Enaxiom is developing cooling infrastructure designed to reduce energy consumption and produce usable water, addressing two of the fastest-growing constraints in data centre operations.

AI infrastructure is scaling at an unprecedented rate. As demand for compute continues to accelerate, a new set of constraints is becoming increasingly visible — not just around power, but also water.

Cooling sits at the centre of both.

At Enaxiom, we are developing a patented cooling system designed to reduce energy consumption while also producing usable water as part of the process.

Following pilot-scale validation, we are now progressing toward modular systems at commercial scale.

AI infrastructure is scaling into physical constraints

The rapid growth of AI is placing increasing pressure on both energy systems and water resources.

Data centres already represent a significant and growing share of global electricity consumption, with projections suggesting demand could reach approximately 945 TWh annually by 2030. At the same time, water usage is becoming a critical factor in site selection and long-term viability.

Large facilities can require substantial volumes of water, with large data centres using millions of gallons of water per day — in some cases comparable to the needs of entire communities.

As AI infrastructure scales, this demand is expected to increase further, placing additional pressure on local water systems and influencing where new facilities can be built.

Cooling is one of the largest contributors to both energy consumption and water use in data centre operations. As AI workloads increase, these pressures are expected to intensify.

As the industry transitions toward higher-density AI infrastructure, these challenges are becoming more concentrated in specific parts of the cooling system.

A different approach to cooling infrastructure

Enaxiom is focused on a specific layer of the data centre cooling stack: heat rejection.

As the industry moves toward liquid cooling, including direct-to-chip and other high-density approaches, more heat is transferred into facility water loops. This increases the importance of how that heat is ultimately rejected from the system.

This is where Enaxiom sits.

We are not replacing primary cooling technologies. Instead, HydroCool is designed to integrate with liquid cooling systems such as direct-to-chip and immersion, operating downstream at the heat rejection layer. Our focus is on high-density environments (100kW+ racks), where we replace or augment conventional infrastructure such as cooling towers and chillers.

This layer is increasingly where energy consumption and water losses are concentrated.

Enaxiom has developed a patented system based on a novel thermodynamic approach to heat rejection. The system is designed to;

Reduce energy use associated with heat rejection
Minimise water consumption and loss
Recover and produce usable water as part of the process

Rather than relying on potable water, the system uses non-potable sources — including industrial wastewater and saline streams — as its evaporative medium. This reduces pressure on drinking water supplies and class A water, and enables a fundamentally different outcome, where cooling systems can contribute to water reuse rather than simply consuming it.

The system is optimised for emerging warm-water facility loop designs, including systems operating around 45°C, which are becoming more common in next-generation AI infrastructure.

This positions Enaxiom as a complementary layer within the broader cooling architecture — improving overall system efficiency and resource use without requiring changes to upstream cooling technologies

HydroCool is designed to operate at the heat-rejection layer of the liquid cooling architecture, downstream of CDUs, where it can replace or augment conventional systems such as cooling towers and chillers.

From concept to validated system

Over the past year, our focus has been on turning this concept into a working system.

Our 40kW pilot unit has now been constructed and tested, with an independent technical review completed. This phase has provided critical validation of the underlying patented thermodynamic approach, while also identifying the practical engineering considerations required for scaling.

As expected at this stage, the process has validated the core system while highlighting opportunities for further optimisation. This is a necessary step in moving from concept to deployable infrastructure.

Scaling toward commercial deployment

With pilot validation complete, we are now focused on scaling the system toward commercial deployment.

The next phase involves developing modular systems at higher capacity, beginning with our 200kW design and progressing toward multi-megawatt installations.

This is the stage where the system becomes more repeatable, more robust, and increasingly aligned with the requirements of real-world data centre environments.

Supported by leading investors and industry networks

Enaxiom recently closed a $1.8M seed round to support this next phase of development, taking the total amount raised to $2.7M.

We are grateful for the support of Black Nova, Antler, Impact Ventures, Waterpoint Capital, Sydney Angels, Epic, Brisbane Angels, and our broader investor group.

We are also part of NVIDIA’s Inception program, supporting our development within the broader AI ecosystem.

“Heat rejection is emerging as one of the most important challenges in scaling AI infrastructure. Enaxiom’s approach directly targets this layer, with the potential to improve both energy efficiency and water use.”

Building for the future of AI infrastructure

As AI continues to scale, the infrastructure required to support it must evolve.

Energy and water are no longer secondary considerations — they are becoming central to how and where data centres are built.

Heat rejection, in particular, is emerging as a critical layer where efficiency gains and resource improvements can have a meaningful system-wide impact.

At Enaxiom, we are focused on developing infrastructure that aligns with this shift.
