Evonik supports next‑generation thermal management with high‑performance dielectric fluids designed for immersion cooling of electrical equipment.
Our solutions enable reliable, efficient heat removal in data centers, high‑performance computing (HPC), and other power‑intensive environments such as energy storage systems.
As power densities rise driven by artificial intelligence and expanding digital infrastructure, traditional air‑cooling approaches are reaching their limits. Immersion cooling offers a safer, more reliable, and more effective alternative—providing superior heat dissipation while enhancing system performance and uptime.
Beyond performance, immersion cooling unlocks new sustainability potential. Waste heat can be efficiently recovered and reused within thermal circuits, for example, for building heating, reducing overall energy consumption and carbon impact.
Evonik Dielectric Fluids Portfolio
Evonik offers dielectric fluids based on Hydrocarbon and Ester technologies, with a strong focus on high‑performance, sustainable Ester solutions.
Key Advantages of Ester‑Based Dielectric Fluids
Low fluid viscosity and favorable thermal transport properties support excellent heat transfer and energy efficiency.
Low toxicity profiles, high flashpoints, high dielectric strength, and advanced water‑handling properties - already proven in established applications such as transformer oils.
Biodegradable formulations with a low carbon footprint contribute to more sustainable cooling solutions.
Additives for Enhanced Performance
In addition to base fluids, Evonik provides specialized additives to further optimize dielectric liquids—for example, to improve low‑temperature fluidity and electrical properties.
