TMC-649 ENGINEERED FLUID

TMC-649 Engineered Fluid from TMC Industries, supplied by Econtrol Devices, is a high-performance engineered fluid designed as a direct replacement for and fully miscible with 3M™ Novec™ 649. It is a clear, colorless, low-odor fluid developed to replace ozone-depleting substances (ODSs) and compounds with high global warming potential (GWP), including sulfur hexafluoride (SF6), HFC-134a, and HFC-245fa. The fluid is formulated to deliver a balance of physical, thermal, and electrical properties while maintaining desirable environmental characteristics, making it suitable for a wide range of industrial heat transfer applications.

TMC-649 Engineered Fluid is a chemically identical replacement for 3M™ Novec™ 649 and is specifically developed for heat transfer applications where non-flammability and environmental performance are important considerations. It is suitable for use in electronics cooling (dual phase), computer and data center cooling, power electronics such as IGBTs and inverters, solar applications, transformers, and other heat transfer equipment. These application areas make TMC-649 a practical solution for industries that require dependable thermal management while maintaining environmental responsibility.

The fluid offers several key features that support its performance across demanding industrial environments. TMC-649 provides a Low Global Warming Potential (GWP), Zero Ozone Depletion Potential (ODP), an Excellent Environmental Profile, and is Noncorrosive. These characteristics contribute to its suitability for applications where reliable performance and environmental considerations are equally important.

TMC-649 is designed to remain stable during operation. It should be used in a sealed system to prevent interaction with water. In the absence of water, the fluid remains remarkably stable at temperatures exceeding 300°C, making it suitable for demanding thermal applications requiring long-term operational stability.

The physical and environmental properties of TMC-649 further support its performance. It has a boiling point of 49°C (120°F), a freeze/pour point of -108°C (-162.4°F), an average molecular weight of 316.04 g/mol, liquid density of 1.60 g/mL, kinematic viscosity of 0.64 cPs, specific heat of 1103 J/kg-K, dielectric strength of 48 kV, dielectric constant of 1.8 at 1 kHz, and no flash point. The fluid also has Zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of 1, offering an environmentally responsible solution for heat transfer applications.

Material compatibility testing shows that TMC-649 has good compatibility with rubber, metal, and a variety of other materials while producing minimal impact during use. Experimental evaluations indicate compatibility with materials including EPDM, Silicone Rubber, Neoprene, PTFE (Teflon 1705), Nitrile, HDPE, Polyamide Nylon 6xt, PVC, Viton, and Polyurethane (PU), making the fluid suitable for use in systems containing a wide range of commonly used engineering materials.

TMC-649 Engineered Fluid is available in multiple packaging options, including 1 Gallon Jug (12 lb / 5.4 kg), 5 Gallon Pail (44 lb / 20 kg), 55 Gallon Drum (550 lb / 250 kg), Sample (2.2 lb / 1 kg), and 275 Gallon Tote available upon request. The product has a 5-year shelf life when stored in its original packaging under normal storage conditions. TMC Industries also offers material re-certification every five years for up to 20 years.

For sustainability, TMC-649 can be recycled and reused through the TMC Industries reclamation program. Used fluorinated fluids can be restored to like-new condition, tested to meet new product specifications, and supplied with a Certificate of Analysis. The reclamation program is backed by a 100% satisfaction guarantee on reclaimed fluids.
