Immersing the Cloud in Sustainability
The future of cloud computing will be marked by exponentially faster data and an ever-growing need for faster information processing. However, more data means more power and more power means more heat. How can cloud and data centers satisfy the need for greater operational efficiencies, while also taking into consideration ways to reduce their tremendous energy and land consumption?
At Dow, we’re helping enable a revolutionary new cooling method for cloud and data centers to tackle both of these challenges using silicone chemistries - DOWSIL™ Immersion Cooling Technology.

Sustainability for a carbon neutral future
- A low-carbon solution featuring low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP) to reduce environmental impact
Stability for an accelerated outlook of data centers
- DOWSIL™ Immersion Cooling is built on stable chemical properties, high material compatibility and excellent dielectric property
- Liquid can get into small spaces and closer to materials that need cooling
Optimized cooling
- Delivers optimal cooling and thermal conductivity with low dielectric constant (ranging from 2.1 to 2.5), and low viscosity (10-30 cSt at 40C) with multiple selections
- Silicone liquid is superior in heat conduction versus air
High cost efficiency
- Reduction of noise, costs, and leakage risks
- Easy to maintain in a convenient location that saves space
- Does not require chillers, CRACs, CRAHs or raised floors
Safety and environmental responsibility
- A safe, high-temperature resistant, and nonflammable liquid
- Unlike natural organic fluids, there are no bacteria or mold growing concerns
Single-phase vs. Two-phase cooling
Single-Phase Immersion Cooling
DOWSIL™ Immersion Cooling Technology is specifically
designed for single-phase immersion cooling applications, as opposed to
two-phase immersion cooling. In single-phase immersion cooling, heat is
transferred to the coolant through direct contact with server components. But,
unlike two-phase immersion cooling, the coolant does not boil off. Instead, it
remains in the liquid phase and is cooled via a heat exchanger.
Single Over Two-Phase Cooling
Single-phase immersion cooling outperforms two-phase cooling in a number of categories, including:
- Non-fluid losses
- Lower operating expenses
- Better hardware stability
- Reduced environment, health and safety (EHS) risks
- More scalable to larger data centers
Overall, the simplicity of a single-phase immersion cooling system allows for greater affordability, easier operations and less maintenance for organizations looking to stay up to speed with their data center operations.
Industries of the Future
As we look to the cloud and data centers of the future, single-phase immersion cooling powered by silicones can help advance the progress of several key industries, including:
5G Edge Computing
Edge computing centers are often located in urban areas, where space is more expensive and less available, but single-phase immersion cooling can help reduce the space needed for these data centers.
Blockchain and Crypto
Blockchain technology requires a large number of machines connected to a network with frequent mathematical calculations and single-phase immersion cooling can help support this network in a more efficient manner.
AI and Machine Learning
Training algorithms for AI applications use a large number of GPUs, which creates a high level of heat and requires a lot of electricity to cool. Single-phase immersion cooling can help keep things cool with less electricity.
High Frequency Trading
High frequency trading requires high-performing systems that rely on timeliness and response speed, and single-phase immersion cooling can achieve higher overclocking possibilities for these scenarios.
