Material Notes:
3M™ Novec™ 649 Engineered Fluid is a clear, colorless and low odor fluid, one in a line of 3M products designed as replacements for ozone depleting substances (ODSs) and compounds with high global warming potentials (GWPs) such as sulfur hexafluoride (SF6) and hydrofluorocarbons (HFCs), such as HFC-134a and HFC 245fa. 3M Novec 649 Engineered Fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with desirable environmental properties.Typical Applications Novec 649 fluid is an effective heat transfer fluid with a boiling point of 49ºC. Novec 649 fluid is useful in heat transfer particularly where non-flammability or environmental factors are a consideration. Examples of systems which benefit from use Novec 649 fluid include:Electronics Cooling (Single or Dual Phase): Power Electronics such as IGBTs or invertersTransformers and other equipment (SF6 replacement) Computer/Data Center CoolingOrganic Rankine Cycle: Diesel EnginesGeneratorsGeothermal ApplicationsSolar ApplicationsInformation provided by 3M
