Introduction

FluoSolv® 649 is a clear, colorless, low-odor, non-flammable heat transfer fluid formulated to match 3M™ Novec™ 649 in every functional and environmental parameter. It is primarily composed of dodecafluoro-2-methylpentan-3-one, offering superior thermal, dielectric, and environmental performance with a boiling point of 49 °C. Ideal for cooling systems requiring both safety and sustainability.

Key Features & Benefits

• Ultra-low Global Warming Potential (GWP = 1) and zero Ozone Depletion Potential (ODP = 0)
• Exceptional safety margin: 8‑hour TWA exposure guideline of 150 ppm with inhalation LC₅₀ well above 100,000 ppm
• Excellent thermal & dielectric performance in compact heat transfer systems (e.g., electronics, power systems)
• Minimal environmental persistence: atmospheric lifetime of ~5 days uponphotolysis

Applications

FluoSolv® 649 is suited for:

• Dual-phase and single-phase immersion cooling of electronics and power devices
• Heat transfer in aerospace, data centers, generators, and solar technologies
• Transformer and inverter cooling, replacing high-GWP gases like SF₆

Material Compatibility

FluoSolv® 649 exhibits excellent compatibility with common engineering materials, requiring no special piping or handling systems:

• Metals: Safe with stainless steel, Aluminum, Copper, Nickel
• Plastics: always test for plastic compatibility
• Designed for direct-contact coolingapplications in sensitive electronics without degradation or interaction

Free Solvent Sample and Vapor Degreaser for Testing

NuGenTec offers a small loaner vapor degreaser and a loaner 5-gallon pail to assist with your testing. The loaner vapor degreaser plugs into a standard wall outlet and fits on a standard pallet. This allows you to test our FluoSolv® solvent in your own controlled environment without immediately changing the solvent in your current equipment.

FluoSolv® 649 is available for purchase in three package sizes:

• 55-gal phenolic lined metal drums
• 5-gal phenolic lined pails
• 1-gal HDPE plastic bottles
