3M Novec™ 774 Engineered Fluid
Categories: Fluid

Material Notes: 3M™ Novec™ 774 Engineered Fluid is a clear, colorless and low odor fluid, and is one in a line of 3M products designed as replacements for ozone depleting substances (ODSs) and compounds with high global warming potentials (GWPs). 3M Novec 774 Engineered Fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with sustainable environmental properties, minimizing the environmental footprint left behind.

Typical Applications: Novec 774 fluid is an effective heat transfer fluid with a boiling point of 74ºC. Novec 774 fluid is useful in heat transfer applications, particularly where non-flammability or environmental factors are a consideration. Examples of systems which benefit from using Novec 774 fluid include:

  • Electronics cooling (single or dual phase)
    • Power electronics such as IGBTs or inverters
    • Transformers and other equipment
  • Computer/data center cooling
  • Electronics testing, pressure compensation, other heat transfer applications
  • Organic Rankine Cycle
    • Diesel engines
    • Solar applications
