Thermal Management

View all products

Many of today’s greatest technological advancements have one thing in common: a need to manage heat. Whether it’s controlling process temperatures in semiconductor wafer manufacturing or getting rid of excess heat generated by data centers, power electronics or avionics, heat transfer is critical to a wide range of applications that enable our modern lives.


At 3M, we use science to make lives better on many levels. Our 3M™ Novec™ Engineered Fluids are developed not only to deliver excellent performance in many heat transfer and liquid cooling system applications, but to do so in a way that doesn’t compromise worker safety or environmental sustainability. Novec Engineered Fluids are dielectric and non-flammable, offer a variety of operating temperature ranges and are low-maintenance, low-mess alternatives to traditional liquid cooling fluids such as water, water glycol or oils used for heat transfer. And they work in many applications, from cold plate cooling for semiconductors to immersion cooling for data centers to spray cooling methods for avionics. If you’re looking for a better way to beat the heat, contact 3M for help.

3M™ Novec™ Engineered Fluids deliver advanced liquid cooling technology to manage heat in various applications.

    Semiconductor wafer and equipment cooling

    Semiconductors sit at the heart of the devices and services that are transforming our world today. To deliver more processing power in smaller packages, wafer manufacturing requires exacting temperature control and precision processes. Equip your fab with the latest two-stage cooling method and technology using Novec fluids for heat transfer.


    At many stages in the semiconductor fabrication process, these heat transfer fluids can provide an efficient, cost-effective, low-maintenance way of controlling process temperatures. Novec fluids don’t require deionisation like aqueous coolants, aren’t flammable and provide excellent temperature uniformity. Find out how Novec Engineered Fluids can help you cool without compromise in:


    • Cold-plate cooling (CPC)
    • Plasma etching
    • Automated testing
    • Chemical vapour deposition (CVD)
    • Photolithography (steppers)

Immersion cooling for electronics

    Data centre immersion cooling

    Data centres are critical to every facet of our lives — from business to communications and entertainment. But large data centres consume enormous amounts of electricity, much of it for cooling. Immersion cooling using Novec fluids allows for simple thermal design and has the potential to lower data centre electricity costs related to cooling by up to 97%.

    Power electronics immersion cooling

    Power electronics are key components of many powerful electric motor applications. The power conversion enabled by these electronics makes possible everything from high-speed electric trains to electric traction systems used in earthmoving equipment. But they require efficient cooling at high density — which can be delivered by a Novec fluid-based immersion cooling system.
