3M Novec 649 Engineered Fluid Ultra Low GWP Heat Transfer
Type: Fluoroketone
Boiling Point: 49°C
Viscosity: 0.40 cSt
GWP: 1
Packing: 5KG / 20KG drum
3M Novec 649 Engineered Fluid is a clear, colorless, low-odor fluoroketone fluid designed as a sustainable heat transfer fluid with an ultra-low global warming potential (GWP) of 1. With a boiling point of 49°C and a pour point of -108°C, this nonflammable fluid delivers exceptional performance in both single-phase and two-phase heat transfer applications across a wide temperature range. Its low viscosity of 0.40 cSt ensures excellent flow characteristics and efficient heat transfer, while its high dielectric strength makes it safe for direct contact with live electronics.
Novec 649 offers an unparalleled environmental profile — zero ozone depletion potential, ultra-low GWP of 1, and an atmospheric lifetime of only 5 days due to photolysis in sunlight. This makes it a sustainable replacement for sulfur hexafluoride (SF₆, GWP 23,900), HFC-134a (GWP 1,300), and HFC-245fa (GWP 1,030). With a wide liquid range, compatibility with most metals and polymers, and a favorable safety profile (exposure guideline of 150 ppm), Novec 649 provides a long-term, environmentally responsible solution for Organic Rankine Cycle systems, electronics cooling, power electronics, and data center immersion cooling.
