Triton Thermal has released a comparison guide clarifying the differences between single-phase and two-phase immersion cooling, helping data center professionals choose the right architecture for high-density AI and HPC deployments based on fluid chemistry, infrastructure and long-term serviceability rather than density alone.
-- Triton Thermal has published a comparison guide addressing a common misconception in data center cooling: that single-phase and two-phase immersion cooling are interchangeable technologies distinguished mainly by density capacity. The guide is aimed at data center managers and infrastructure decision-makers evaluating cooling architecture for high-density AI and HPC deployments, and argues that the choice between the two technologies depends on fluid chemistry, tank design, facility infrastructure and long-term serviceability rather than density alone.

The guide arrives as liquid cooling adoption accelerates sharply across the AI data center sector. The share of liquid-cooled AI servers is projected to rise from 15 percent in 2024 to 76 percent in 2026, according to Goldman Sachs research, as next-generation AI racks push toward densities Deloitte projects could reach 370 kilowatts this year. As facilities move quickly toward cooling architectures that many teams have limited operational experience with, the risk of treating single-phase and two-phase immersion as interchangeable - rather than as distinct systems with different fluid, maintenance and infrastructure requirements - grows accordingly.
The two architectures differ fundamentally in how their dielectric fluid behaves, explains the team at Triton Thermal. Single-phase fluid stays liquid throughout the cooling cycle, transferring heat through direct contact and pumped circulation to an external heat exchanger. Two-phase fluid is engineered with a low boiling point, so it vaporizes directly off hot components and carries heat away through that phase change before condensing back to liquid.
The new guide notes that fluid chemistry deserves particular scrutiny for two-phase systems, since some fluorinated dielectric fluids historically used in that architecture have faced increased environmental and regulatory attention tied to PFAS compounds, which can affect long-term fluid availability.
In addition, the two systems also place different demands on facilities and maintenance teams. Single-phase systems generally integrate with cooling infrastructure, such as CDUs and dry coolers, that facilities teams already maintain in other liquid-cooling environments. Two-phase systems require sealed-vessel and vapor-containment management, which typically calls for specialized training or vendor support.
Triton Thermal's guide notes that architecture choice does not have to be a facility-wide decision; mixed deployments, with single-phase used broadly and two-phase reserved for the highest-density zones, are becoming increasingly common.
