THE global data centre industry is experiencing unprecedented growth, fuelled by an insatiable demand for advanced computing power. Market reports predict the industry will grow from USD244 billion in 2020 to USD519 billion by 2030 at a compound annual growth rate (CAGR) of 10%. This expansion is driven by transformative technologies like 5G communications, artificial intelligence (AI), and crypto mining, which demand higher performance from processors and servers.
However, with greater performance comes the challenge of effective cooling. Traditional air-cooling systems, reliant on space, energy, and water, are no longer sustainable for hyperscale and colocation data centres. “Immersion cooling has emerged as a groundbreaking solution for managing the escalating cooling demands of to-day’s powerful processors and servers,” says Jarryd Tate, technical application engineer at Fuchs Lubricants South Africa, which is at the forefront of this transition, providing innovative cooling solutions tailored to meet the needs of the digital revolution.
Liquid cooling, long the ‘go-to’ solution for high-performance computing centres, is now becoming a mainstream solution for data centres. Among its forms, immersion cooling stands out as the most capable of handling future challenges. This technology submerges hardware components in specially engineered fluids, delivering unparalleled efficiency.
Single-phase immersion coolants are gaining traction due to their zero ozone depletion and global warming potential, alongside simpler designs that reduce operational complexity. Immersion cooling systems significantly lower energy consumption, reduce water usage, and require less maintenance, leading to a decrease in overall operating expenses. In addition, these systems improve uptime ratings, processor performance, server density, and overall power-usage effectiveness.
Beyond efficiency gains, immersion cooling offers considerable environmental benefits. It lowers a facility’s carbon footprint and energy usage while enabling waste heat capture and reuse. The design advantages are equally compelling: facilities can eliminate costly chillers, air handlers, and rack fans while minimising concerns about regional climate, dust, and air pollution. “Immersion cooling not only addresses the operational challenges of traditional systems but also aligns with global sustainability goals, making it an essential innovation for future-ready data centres,” says Tate.
Despite its advantages, some operators hesitate to adopt immersion cooling due to concerns about handling large volumes of fluids and potential disposal requirements. Fuchs addresses these challenges with its modular services for immersion coolant management. Leveraging decades of experience in chemical process management, the company provides tailored solutions covering the full lifecycle of immersion coolants, from initial implementation to ongoing maintenance. This ensures that the benefits of immersion cooling are sustained over time.
