Airsys partners with Oleon

Oleon’s Qloe dielectric fluid has been approved for use in Airsys’s award-winning LiquidRack™ system, following a comprehensive testing program conducted at Airsys's laboratories in South Carolina, USA.

The collaboration between Airsys and Oleon comes at a critical moment in the evolution of Data Centre infrastructure. As demand for high-performance computing, AI, and edge applications continues to grow, so too does the need for more efficient and sustainable cooling solutions, that can manage the high heat loads created by these technologies.

Liquid cooling is rapidly gaining prominence as the preferred solution for modern Data Centres. Traditional air-based systems are increasingly unable to cope with the rising heat densities of today’s powerful processors. In contrast, liquid cooling provides superior thermal management, enabling higher performance while reducing energy consumption.

The LiquidRack™ represents a breakthrough in Data Centre cooling technology, leveraging precision spray liquid cooling to deliver superior thermal performance. By spraying the CPUs directly, LiquidRack™ significantly enhances the heat transfer coefficient and reduces the amount of fluid required compared to traditional immersion cooling methods. Its ability to operate effectively at elevated fluid temperatures enables year-round free cooling, eliminating the need for mechanical chillers and drastically lowering energy consumption. These elevated fluid temperatures also offer more options for heat recovery, enabling the heat generated by the Data Centre to be repurposed for district heating or hot water usage.

"Collaborating with Oleon has been an exceptional experience,” said Matthew Thompson, Managing Director Europe at Airsys, “Both Oleon and Airsys share common values and a unified vision to advance liquid cooling technologies. Together, we are committed to drive the Data Centre industry towards a greener, more sustainable future."

Oleon’s Qloe range of dielectric fluids is derived from renewable plant-based sources and has been engineered to deliver exceptional performance. These fluids offer excellent dielectric strength, thermal transfer capabilities, and material compatibility — all at a low viscosity. Qloe is biodegradable, non-toxic, and has zero global warming potential, making it a sustainable and environmentally responsible options available today. With high flash points and safe handling characteristics, Qloe is ideally suited for advanced cooling applications.

“Data centre efficiency is about performance and sustainability, driven not only by ideals but also by necessity”, said Maarten Trautmann, Immersion Cooling Programme Lead at Oleon, “Scarcity in energy and water prove to be a significant challenge for regions and companies that

have big digital ambitions, and this situation won’t change any time soon. This is the kind of partnership that enables those ambitions.”
