Meet QLOE, a range of data center cooling liquids by Oleon. Discover our next-generation cooling liquids that balance sustainability, safety, and performance.

Why QLOE?

  1. Safety
    Our immersion cooling liquid is non‑labelled, meaning it is not classified as toxic to humans, irritant, or hazardous. This helps eliminate potential health risks and supports a safer working environment. It also simplifies installation and maintenance, as the liquid can be handled without additional hazard-related precautions.
  2. Sustainability
    Oleon develops plant-based dielectric liquids for IT cooling, combining strong performance with a very low carbon footprint. The liquids are renewable, biodegradable, and PFAS-free, offering a safe and environmentally responsible cooling solution.
  3. Performance
    Our liquid has been tested across a variety of system setups, demonstrating excellent material compatibility. With a flash point of 210°C, it offers best-in-class operational safety. Its thermal and dielectric performance is fully aligned with industry standards and guidelines.
