“This approach not only reduces a data center’s energy usage by 60%, but also minimizes water usage compared to traditional cooling methods, aligning with organizations’ sustainability goals.”

What brought about the development of
immersion cooling technology?


Data centers are central to the storage, processing, and administration of extensive digital information. They underpin critical technologies such as cloud computing and online communication, propelling growth and innovation within the digital economy. Data centers also consume about 1.5% of the world's electricity, resulting in substantial heat generation.

With this in mind, approximately five years ago, forward-thinking customers approached us in search of cutting-edge technologies that enhance thermal conductivity and heat transfer to meet the evolving demands of the next evolution in data center design They were seeking a holistic solution that encompassed both cooling liquid and thermal management materials.

Traditionally, data centers mainly relied on fluoro-based cooling fluids to meet the intricate cooling needs necessitated by the substantial heat generated within these facilities. However, shifts in the industry landscape have prompted us to explore alternative options. In response to these challenges and our commitment to meeting our customers' evolving needs, we ventured into uncharted territory. This endeavor resulted in the development of a revolutionary liquid cooling technology which possesses the exceptional ability to transfer heat efficiently, supporting high-powered data center designs, all while driving sustainability and cost-effectiveness.

Why is immersion cooling technology more
important than ever before?


The rising carbon footprint of data centers, coupled with rising power and heat demands, underscores the need for advanced cooling solutions that combine performance and sustainability. So, how can we achieve this superior level of cooling? The answer lies in harnessing the potential of immersion cooling – a technique involving the complete submersion of electrical and electronic components, including entire servers and storage devices, in a thermally conductive yet electrically insulating liquid coolant. This approach not only reduces a data center’s energy usage by 60%, but also minimizes water usage compared to traditional cooling methods, aligning with organizations’ sustainability goals.

Our DOWSIL™ Immersion Cooling technology stands out as a hybrid silicone-organic fluid, boasting exceptional heat conduction capabilities when compared to conventional air-cooling methods. Specifically designed for single-phase immersion cooling applications, this technology can penetrate confined spaces and effectively cool electronic components. Additionally, it supports increased server load densities and enhanced computer performance while substantially reducing both data center space requirements and power usage. In the long-term, these advantages will be critical in enabling technologies heat-intensive technologies shaping future industries, such as 5G+ edge computing centers, high frequency trading, blockchain, crypto mining, AI, and machine learning.

How will immersion cooling technology help
organizations advance toward a more
sustainable future?


The rapidly evolving technological landscape, driven by the increasing reliance on cloud computing and data centers, has led to a soaring demand for high-performance computing platforms. Notably, AI applications, with their intensive processing requirements, generate substantial heat and demand significant electricity for cooling.

As organizations strive for greater operational efficiency and a positive environmental impact, they must carefully consider the technologies and cooling methods employed in their data centers. DOWSIL™ Immersion Cooling technology, engineered for single-phase immersion cooling applications – where the coolant retains its liquid state throughout -presents a range of benefits. In the single-phase system, the coolant remains in liquid form while efficiently extracting heat through direct contact with server components and then directing it through a heat exchanger. These benefits include reduced operating costs, enhanced hardware stability, minimized environmental, health, and safety risks, and improved scalability for larger data centers.

In a world where sustainable business practices are paramount across all industries, the adoption of immersion cooling in data centers represents an impactful contribution toward a more sustainable future for all.
