• AI Power Density: As of March 2025, the GB200 NVL72 platform from NVIDIA pushes rack-level power to 120kW. Phase change cooling systems remove heat at the source, facilitating denser configurations of computing accelerators. The trend toward denser configurations of computing accelerators will persist due to advances in AI training and inference which put increased demands on rack level power in the range of 120kW during 2030.
• Water Efficiency: Water efficiency of cooling systems is becoming a primary consideration for data center operators in regions effected by droughts. Microsoft announced a zero-water cooling design for new data centers in August 2024, and several 2025 projects are evaluating immersions systems. In the next 3-5 years, data center operators will shift site selection and permitting in accordance with water conservation goals.
• Fluids and Regulation: The phase change liquid cooling market will shift to the use of fluids with a low global warming potential (GWP). As 3M completed their exit of PFAS manufacture in December 2025, suppliers will have an incentive to develop new alternative fluids with boiling points and dielectrics comparable to existing fluids. Regulatory controls will impact the sourcing, qualification, and operating costs of cooling systems.
• Modular Deployment: Colocation data center providers are developing factory made immersion tanks that do not require complete construction of hallways. 2025 saw continued deployments by GRC and Liquid Stack of their modular systems based around 20-40 kW cabinets. Standardized modules will help shorten deployment times. * Service-based adoption: Cooling service providers are reducing the burden on customers by offering fluid management, monitoring, and tank maintenance under long-term deals. This will drive adoption of smaller systems in 2025 to 2027 as providers begin to focus more on the service rather than the one-time hardware sale.

Over the coming five years, phase change liquid immersion cooling will dominate markets where economic incentive to avoid air cooling begins to outweigh the potential challenges of higher rack density. Selective adoption will continue for the foreseen future due to the high market entry barriers, such as the cost and disruption of system retrofits, the required chemical certifications and warranties for fluids, and qualification for new fluid immersion technology. The strongest markets for liquid immersion cooling will be AI infrastructure, but water policy will likely constrain market size and growth

Recent Developments in the Phase Change Liquid Immersion Cooling Server Market

Phase change liquid immersion cooling servers will experience an increase in activities through 2025-2027 as artificial intelligence workloads push rack densities beyond what conventional air cooling can accommodate.

The market is transitioning from a stage of demonstrations to the development of repeatable energy and space savings goal projects.

• Hyperscale Deployment Commitments: Microsoft increased liquid cooling trials for AI infrastructure in March 2025. This step indicates high demand for systems designed to support racks in excess of 100 kW. This validates phase change designs, and therefore, data center operators now specify immersion-ready capacity for new builds.
• Specialty-fluids Investments: Shell reported that it was developing immersion cooling fluids for data centers in 2025, and focused on dielectric formulations, that aim to lower thermal resistance and reduce the maintenance risk. The availability of commercial fluids may determine if users can go beyond the pilot scale.
• Server-platform Integration: In 2025, Dell Technologies and Intel continued their work to validate liquid cooling systems for high performance computing. They continued to develop capabilities around high-power processors and factory-integrated cooling systems that enhance the sealing and monitoring of liquid cooling systems, lowering their complexity to a level suitable for colocation systems.
• Data-center Efficiency Mandates: The revised Energy Efficiency Directive of the European Union began influencing reporting and influencing infrastructure planning in 2025. This directive places a greater focus on the energy performance of data centers. Operators will be motivated to invest in this technology to improve the power usage effectiveness and lower cooling infrastructure costs.
• AI Infrastructure Expansion: With Nvidia's data center revenue of $115.2 billion for fiscal year 2025 (reported in February 2025), we now understand the scope of the growth of accelerator-centered capacity. Increased heat loads will drive data center operators towards immersion computing architectures (especially where mechanical cooling infrastructure will not allow for more power onto the grid).

There are good financial reasons for operators to use immersion architectures, but those reasons wholly rest on reducing lifecycle costs. Operators need immersion technology that will allow them to recover liquids, compliance with fire codes, and will provide reliable services. Companies that can deliver systems integrated with fluid chilling technology and include server and controls packages and monitoring systems will be able to provide systems with expedited delivery. Over the next five years, AI density, restricted power availability, and increasing efficiency demands will push advanced data center design to incorporate immersion computing for some main-stream data center deployments. There will still be very uneven growth rates as fluid standards will slow adoption as will the costs of retrofitting.

Strategic Growth Opportunities in the Phase Change Liquid Immersion Cooling Server Market

The increased rack power density. These are causing issues for data center operators due to increasing electricity, water, and space needs. Lucintel predicts that, in the next few years, new client projects will increase, thanks to the hyperscalers and a focus on efficiency.

• High Performance and AI Workloads: Liquid immersion cooling is used to address dense rack mount GPU workloads that become uneconomical with air cooling. NVIDIA launched the GB200 NVL72 platform in March 2024 and is able to fit 72 GPUs per rack, highlighting the design's thermal limits. Over the next 3-5 years, immersion cooling will see the greatest demand for workload deployment due to AI infrastructure workloads.
• Edge and Telecom Deployments: Cooling technology with low thermal capacity and low maintenance cooling systems are needed in edge deployments. According to the GSMA, mobile data traffic continued to increase sharply in February 2025. This supports the deployment of thermally efficient edge computing.
• Low Carbon Premium Data Centers: Data center operators are looking for chiller utilization alternatives and water minimization designs. Microsoft announced in August 2024 that the design of its newest data centers will be without water cooling. This will also create demand for phase change systems as clients start linking procurement decisions to their water stewardship and carbon reporting goals.
• Retrofit and Colocation Solutions: Present infrastructure provides a large target customer base because legacy racks cannot accommodate AI hardware. Equinix reported 280 data centers spanning 72 metro areas in February 2025. Immersions tanks can offer flexible, collocated AI solutions. It provides additional service offerings with a large potential revenue stream.
• Specialized Fluids and Lifecycle Services: Fluid formulation and management further enhance profit potential beyond equipment sales. With the October 2025 launch of their expanded activity of immersion-cooling fluids, Shell illustrates the market's interest. In the next 3-5 years, validated fluid systems with simplified environmental compliance should allow customers to replace warranty risk systems.

Combining hardware and software solutions should be the goal of most suppliers. However, because of the expected uneven demand, AI clusters and space restricted facilities should take priority over conventional enterprise sites. Thriving in this market requires significant field coverage, compelling data, and feasible financing options. Other components should be improved to ensure reliable performance. In the end, potential customers will be most concerned with product reliability.

The factors responsible for driving this market include:

• Artificial Intelligence Workloads: With the rapid deployment of artificial intelligence and high-performance computing, along with large language models, there is a rapid increase in the power density of racks. A number of major data center operators continue to announce large-scale artificial intelligence deployments, further perpetuating demand for pharmaceutical cooling in data center infrastructure. Phase change immersion systems can absorb heat right at the source and help maintain optimal performance of the servers. In the next three to five years, dominant servers with sophisticated processors and more accelerated computing will entice data center operators to deploy cooling technologies capable of supporting high heat loads in small spaces.
• Energy Efficiency: Price increases and the strategic use of sustainability targets drive data centers to reduce the energy consumed by cooling. Increasing electricity demand and the resulting high costs mean substantial growth for data centers and continue to challenge the industry in 2025. Cooling systems consume a large percentage of a facility's total energy. There are opportunities to reduce the energy consumed by data centers using innovative phase change systems to cool data centers. Phase change systems allow data centers to depend less on air conditioning, resulting in greater energy efficiency and better thermal equality with less cooling equipment. Over the next three to five years, energy consumption will drive demands for higher energy efficiency and demands for lower carbon emissions. This will further drive the use of immersion cooling technologies.
• Data-center Expansion: Increasing demand for cloud and edge computing, digital services, and AI will continue to drive new data center investments. By January of 2025, the capacity planning for data centers remained strongly influenced by the growth of artificial intelligence and higher rack densities. Data centers can adopt high-density computing in locations that have less available space for air cooling using phase change immersion cooling technology. This technology also supports retrofits and specialized high-performance installations. In the next three to five years, the digital infrastructure will increase and provide further opportunities for immersion cooling systems in enterprise, hyperscale, and colocation data centers.
• Product Innovation: Recent advancements in dielectric fluids, sealed tanks, heat exchangers, monitoring software, and server compatibility are making immersion cooling systems easier to implement.

It is expected product innovations will continue to decrease the barriers of adoption over the next 3 to 5 years, and phase change cooling will shift from rare, unique deployments to standard deployments in data centers.
• Infrastructure and Regulatory Pressure: Governments and utilities have begun to examine the power and water consumption of data centers, as well as their impact on the environment. In 2025, the European Union continued to mandate that data center operators provide reports about the energy efficiency of their operations. The use of phase change immersion cooling can enable data center operators to become less reliant on water and more efficient with respect to their power consumption. Because of the expected regulatory environment and the anticipated utility environment, data center operators will probably select technologies that provide greater computing capacity in less space and less power. In the next 3 to 5 years, cooling systems will be impacted by changes in regulations related to efficiency and sustainability, and changes related to permitting.

The challenges facing this market include:

• The Outlay at The Outset: Due to the highly technical nature of this type of cooling, initial outlay not only includes the design and creation of the immersion tanks, but also dielectric fluids, and cooling machinery as well as risk-considerate server installation. In 2025, capital discipline was still a priority for the majority of project developers, as the construction and electricity infrastructure costs remained as they were. All of this negatively impacts the justification for small scale deployments and lower density applications. Consideration must be given to potential savings due to reduced cooling costs over time as well as longer equipment lifespans. Adoption and deployment are expected to occur over the next 3 to 5 years with decreased prices on systems, improvements in financing, and conclusively positive lifecycle economics.
• Compatibility and Maintenance: The first construction of an immersion cooled data center can involve service agreement modifications, design changes, fire protection, and staff relearning as well as training. For 2025, the majority of the data centers opted to use air cooled equipment due to the economies of scale, coupled with a sympathetic service network. Since 2025, a number of challenges and potential concerns revolve around the complexities of operations involving the handling of fluids, component replacement, and keeping the system free of contamination and impurities as well as staff who lack the necessary specialization. In the next 3 to 5 years, confidence and deployment risk can be reduced with improvements in design and manufacture, remote monitoring, and staff specialization training.
• Fluid, Safety, and Standardization Concerns: Dielectric fluids must maintain a consistent level of thermal performance without compromising safety, environmental, storage, or disposal concerns. In 2025, customers showed more interest in fluid chemistry and sustainability and more long-term material partnerships. Speed bumps to procurement and system integrations with inconsistent specifications provided by various suppliers. Uncertainty remains about leaks, potential fluid handling problems, and the end of life treatment of the fluid. In the next 3 to 5 years, the industry will have to pay more attention to advances in fluid management and standardized testing in order to create a more adverse business climate for the competition.

The phase change liquid immersion cooling server market has huge opportunity for growth due to the changing landscape of data center design for artificial intelligence, high density computing, energy costs, and sustainability. Innovation and growth in supporting infrastructure will allow for adoption. Even with the challenges created by capital costs, compatibility, complexity and maintenance of fluid systems, and the associated risks, the market will grow with standardized equipment, reliable supply chains, validated lifecycle savings, and a trained service staff. As deployments mature, phase change immersion cooling is likely to move from specialized applications towards broader use in various markets like hyperscale, enterprise, edge, and high performance computing.
