DAISAVE is a new low‑GWP fluorinated liquid developed by Daikin Industries. Combining excellent thermal and chemical stability with zero ozone depletion potential, low viscosity, and strong dielectric properties, it is suitable for a wide range of applications, particularly in cleaning and cooling. For data centers, it can be used as a coolant for direct liquid and immersion cooling, helping to address the heat‑generation challenges of high‑performance AI servers. In this presentation, I will introduce DAISAVE in more detail.
