    Immersion cooling working fluids for voltage-changing power electronics applications.

    Immersion cooling allows power electronics to be efficiently and uniformly cooled by immersing them in dielectric fluids that are safe for electronic contact.

    3M™ Novec™ Engineered Fluids offer wide operating temperature ranges, have excellent materials compatibility and are simple to maintain, making Novec fluid-based immersion cooling an excellent alternative to air-, water- or oil-cooled systems.

A smarter solution than other cooling alternatives

Cooling power electronics using an immersion cooling system offers many advantages over the alternative cooling methods.

  • Immersion cooling offers more consistent and efficient cooling than air, which allows greater density of electronic components — critical to creating smaller power electronics.*

    Water cooling
    Using water to cool power electronics requires significant complexity to ensure that the water doesn’t contact the electronics and create a short. 3M™ Novec™ Engineered Fluids are dielectric and safe for contact with electronics, simplifying the system.*

    Oil cooling
    The various oils sometimes used for heat transfer in immersion cooling for power electronics are all flammable at some temperature and leave residue. 3M™ Novec™ Engineered Fluids are non-flammable, resulting in greater safety, and leave no residue, for easier maintenance.*

    All the performance without compromise

    The Novec promise is performance without compromise. Our engineers purposefully developed Novec Engineered Fluids with worker safety and environmental sustainability in mind. These fluids feature:


    • Low environmental impact, with zero ozone depletion potential (ODP) and low global warming potential (GWP), compared with conventional hydrocarbon coolants*
    • Strong regulatory compliance — not scheduled for restriction or phasedown
  • A jug of 3M™ Novec™ Engineered Fluids with technical data on the front.

    The power of next-generation cooling solutions.

    Excel in heat transfer applications with products that feature.


    • A wide range of operating temperatures for use in different applications
    • Options that are compatible with either single-phase or two-phase immersion cooling systems
    • Excellent materials compatibility to avoid damage to equipment
    • A range of vapour pressures, densities and molecular weights
    • High dielectric strength that makes them safe for contact with critical electronics
