Enaxiom develops Hydrocool, a patented system aimed at the heat-rejection layer of data centre cooling that is designed to work alongside modern liquid cooling approaches such as direct-to-chip and immersion cooling. The technology uses non-potable and wastewater streams and is engineered to recover high-quality water as a by-product, effectively contributing to water reuse. The system is based on about a decade of research and a 40kW pilot demonstrated proof of concept. Enaxiom is now pursuing modular commercial-scale systems and plans to expand into the U.S. market. The company was founded in Sydney in 2023 by Bijan Rahimi and CEO Tia Collings. To date it has raised US$2.7 million and is deploying its recent Seed funding toward commercial deployment and hiring.
