Immersion cooling

An advanced cooling technology that uses dielectric liquid to cool servers more efficiently than traditional air cooling.
Servers next to each other

Air cooling is reaching its limits

With the rapid adoption of high-density computing, traditional air cooling is reaching its limits, making it increasingly difficult to remove heat effectively. This is where liquid cooling technology comes in. Due to their superior heat transfer properties, liquids are far more effective at removing heat than air. Think of cooling a burned finger under running water rather than blowing air on it. As a result, liquid cooling is becoming an increasingly popular and widely adopted cooling method in modern data centres.

"QLOE is a next generation immersion cooling liquid that balances sustainability, safety and performance."

Immersion cooling is the future

Immersion cooling uses dielectric liquids to efficiently remove heat by fully submerging servers. To ensure optimal performance and reliability, these liquids are thoroughly tested on material compatibility, thermal and oxidative stability and dielectric properties. After extensive validation, our QLOE IC 8313 product became the first plant-based ester to meet all OCP requirements guidelines, delivering high performance while setting a new standard for safety and environmental responsibility.

Our benefits

  • Sustainability

    QLOE IC 8313 is a fully plant-based immersion cooling liquid that provides a sustainable alternative to petrochemical coolants. PFAS-free, biodegradable, and with zero Global Warming Potential during use, it helps data centers reduce their environmental footprint while supporting sustainability goals.

  • Safety

    QLOE IC 8313 is engineered with safety in mind. Its high flash point of 210°C enhances thermal stability and reduces fire risks, while its non-toxic, non-classified formulation poses no respiratory hazards to humans. This makes it a safe and reliable choice for environments where health, safety and regulatory compliance are essential.

  • Performance

    QLOE IC 8313 is designed to meet OCP requirements for immersion cooling, delivering excellent thermal and dielectric performance. Its low viscosity ensures efficient heat transfer, while its high stability and broad material compatibility help maximize the lifespan of both the liquid and the equipment.
