TMC-49 is a fluorinated liquid aimed at data mining centers and electronic products for immersion cooling because of its prominent thermal stability and great efficacy of heat radiation.  TMC-49 is non-flammable, insoluble in water, and not hazardous to human health.

TMC-49 can also be used as a cleaning agent for electronic products or electric parts accredited to its high dielectric strength.

Two-Phase Cooling
In a two-phase immersion-cooled system, servers are sealed inside a bath of specially engineered fluorocarbon-based liquid. Because the fluid has a low boiling point (often below 50°C vs. 100°C for water), heat from the servers easily boils the surrounding fluid. The boiling of the liquid causes a phase change (from liquid to gas), which gives two-phase immersion cooling its name.
The vapor is then condensed back to the liquid form via water-cooled condenser coils, which are integrated into the top of the sealed racks. The condensed liquid drips back into the bath of fluid to be recycled through the system.

Safety and Handling
TMC-49 is not a flammable or toxic liquid. It requires few conditions during application. For more information, please refer to the Material Safety Data Sheet (MSDS)

Keep in room temperature and ventilation and dry. Keep the container sealed when not used.

Shelf Life
The shelf life is 36 months under recommended storage conditions. The product stored past expiration may still be used if the analysis results so indicate.

Shipping Policy

We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
