Nexalus, a leader in advanced liquid cooling solutions, has announced a partnership with Hewlett Packard Enterprise (HPE) to integrate its energy-efficient cooling technology into HPE’s server lineup. This collaboration aims to tackle the growing energy and environmental challenges faced by data centres, which currently contribute over 100 million tonnes of CO2 annually. The goal is to transform data centres into clean energy-generating assets, offering a circular economy solution that reduces energy consumption and emissions.
As part of the partnership, Nexalus will deploy its liquid cooling systems in three of HPE’s most popular server models: the HPE ProLiant™ DL360, DL365, and DL380a. These servers, now available with Nexalus’ proprietary cooling technology, promise enhanced thermal performance, reduced energy consumption, and significant improvements in data centre sustainability.
With increasing pressure on data centres to minimise energy use and environmental impact, the partnership between Nexalus and HPE presents a timely solution. Nexalus’ liquid cooling technology allows data centres to repurpose thermal energy that would otherwise be wasted with traditional air-cooling methods. Unlike air, which has limited thermal properties, Nexalus’ liquid cooling solution can transport 4,000 times more thermal energy per unit volume, unlocking the potential for energy recovery.
In a typical 20MW data centre, Nexalus’ technology can cut energy consumption by up to 35%, potentially reducing CO2 emissions by up to 23,000 tonnes. Additionally, the technology can convert waste heat into green energy, powering up to 6,000 homes and offsetting an additional 24,000 tonnes of CO2 emissions.
Kenneth O’Mahony, Co-Founder and CEO of Nexalus, emphasised the transformative potential of this collaboration and said, “Our technology turns data centres into energy-efficient hubs that generate clean energy by reusing thermal energy, reducing emissions. This collaboration offers a unique opportunity to rethink data centre power demand, positioning these facilities as thermal power stations that could supply clean energy to nearby cities or industries.”
Nexalus’ cooling technology offers several advantages over traditional air-cooling systems. It enhances cooling efficiency by improving heat removal from high-performance servers, ensuring optimal operational performance. This technology also leads to significant energy savings by reducing the need for energy-intensive air conditioning systems, resulting in lower power consumption and operational costs.
Additionally, Nexalus’ closed-loop water cooling design reuses the same water, drastically reducing water consumption and achieving a Water Usage Efficiency (WUE) of zero. The technology also enables more than 10 times higher computing density in data centre racks, allowing for better space utilisation. Furthermore, Nexalus’ approach contributes to sustainability efforts by reducing carbon footprints and transforming data centres into energy-generating assets, supporting global environmental goals.
Nexalus’ advanced cooling technology, using patented jet-impingement technology, provides superior CPU and GPU cooling, ensuring long-term performance in high-temperature environments. The sealed server design prevents contamination, reduces maintenance needs, and minimises downtime. The collaboration also results in quieter operations (reducing noise by at least 20 dB), longer server lifespans, and increased adaptability to extreme climates.
“We are excited to collaborate with HPE to bring our cutting-edge cooling solutions to some of the most trusted servers in the industry,” said O’Mahony, adding, “This partnership underscores our shared commitment to sustainability and delivers top-tier solutions for data centres, enabling customers to meet growing performance demands while reducing environmental impact.”
