“Our industry has reached the practical limits of air cooling. We founded LiquidStack with the sole purpose of driving continued performance gains in computing through our breakthrough technology and unmatched experience. We embrace all forms of liquid cooling, which outperforms air cooling across every possible metric: heat rejection capacity, energy efficiency, water usage, space utilization, flexibility and positive, sustainable climate impact. Our goal is to do more than simply change minds. We aim to change the world for the better.”

The New Cooling Imperative

Data centers face mounting pressure to increase IT power density while minimizing energy and water use. The era of superficial “green-washing” is over. Prominent data center owners and operators have committed billions of dollars to achieve carbon-neutral and carbon-negative sustainability goals.

But the pressure to drastically improve energy efficiency doesn’t stop at the data center. Chip manufacturers also face increasing pressure to create more dense and powerful processors. Unfortunately, they have hit insurmountable constraints imposed by the limitations of air cooling, even when supplementing air cooling with some forms of liquid cooling.

Liquid cooling removes these barriers for the entire data center ecosystem, from data center designers/owners/operators to hardware and semiconductor companies. This represents an inflection point for the industry and opens up possibilities not just in terms of data center design and operation, but also in terms of what computing can accomplish (AI, IoT, Big Data, Edge, etc.)

Liquid cooling provides the gateway and enables the future of sustainable hyperscale, HPC and edge computing. It will positively impact technology leveraged by the world’s largest corporations and everyday people accessing cloud services at the edge. The future is now – the future is liquid cooling.
