TMC-49 Specialty Fluid is a two-phased coolant aimed at data centers and electronic products for immersion cooling because of its prominent thermal stability and excellent efficacy of heat radiation. TMC-49 is non-flammable, insoluble in water, and not hazardous to human health. TMC-49 is a hydrofluoroolefin (HFO) dielectric fluid with zero ozone depletion potential (ODP) and a very low GWP of 20.

No Flash Point
Non-Flammable
ODP of 0
GWP of 20

TMC-49 is a high-performance, two-phase, closed-loop liquid cooling solution designed for processors with extreme power demands (2500W+). It uses direct-to-chip cooling with a waterless heat transfer fluid, eliminating risks of leaks or corrosion while efficiently extracting and dispersing heat. Scalable for new or retrofitted data centers, it supports computing power of 120 kW and above, with a single cabinet handling up to 160 kW of heat dissipation. The power consumption is reduced from 12kW to 9kW.

Power usage effectiveness (PUE) is less than 1.1 of TC4600E-LP server by Sugon whose power density of a single cabinet is 160kW.

TMC-49 2-phase coolant has successfully been applied to supercomputing or IDC.

APPLICATIONS:

Heat Transfer Agent for Companies like Data Mining
Two-Phase Coolant
Data Centers
Supercomputing Centers
Energy Storage Power Centers
Cleaning agent for electronic products or electric parts
