Heat Transfer Solutions for Aerospace, Aviation & Military Applications

Thermal management fluids engineered for high-flying performance

As the complexity and sophistication of electronic systems for defense and aerospace applications continue to grow, so do the thermal management challenges posed by these systems.

From the dense circuitry of today's advanced avionics and electronic countermeasures devices to the tightly-packed power electronics of commercial fly-by-wire systems, more and more heat is being confined to ever-smaller spaces. Removing this waste heat is critical, in order to maintain reliable performance in extreme environments.

3M™ Novec™ Engineered Fluids are unique dielectric heat transfer liquids used to solve a wide range of thermal management challenges in aviation, data centers, control rooms, guidance systems and other essential applications.

Mission-critical heat transfer solutions

Whether the application is indirect or direct contact, evaporative or single phase cooling, Novec heat transfer fluids are ideally suited for use as cooling media in the most demanding scenarios. Novec fluids are nonflammable, evaporate cleanly in case of spills and maintain low viscosity and high heat transfer efficiency over a wide operating temperature range.

  • Highly-efficient heat transfer properties
  • Stable at temperatures ranging from 150°C to 300°C
  • Maintain low viscosities at temperatures down to -80°C
  • Good materials compatibility
  • Will not hydrolyze or degrade over time to form deposits that can occlude fluid passages
  • Low toxicity
  • Non-flammable
  • Zero Ozone Depletion Potential
  • Low Global Warming Potential
  • Exempt from the U.S. EPA definition of a VOC

Novec heat transfer fluids require little maintenance and will not damage electronic equipment or circuits in the event of a leak or other failure. Unlike oil-type heat transfer liquids that trap dirt, and are difficult to clean up, Novec fluids evaporate quickly and completely, leaving no residue.

Novec fluids offer an outstanding balance of thermal management performance, low environmental impact and worker safety, making them a long-term, sustainable heat transfer solution in many critical applications. Novec fluids have been recognized by a number of industry and regulatory bodies around the world, including approvals of Novec 7100 and 7200 fluids for "use without restriction" under the U.S. EPA's Significant New Alternatives Policy (SNAP). Because of their favorable environmental profile, choosing Novec heat transfer fluids can help support U.S. DOD initiatives to procure environmentally preferable products. Replacing perfluorocarbon (PFC) or perfluoropolyether (PFPE) heat transfer fluids with Novec fluids results in greenhouse gas emission reduction of p to 99%.
