Thermasolv CF4 is a dielectric heat transfer fluid from Inventec Performance Chemicals. It is built for single-phase immersion and direct cooling, with very low viscosity to cut pump energy.
Key Features of Thermasolv CF4
- Viscosity 0.71 cSt
- Dielectric strength 40 kV
- Perfect for semiconductor tool cooling
What Is Thermasolv CF4 Used For?
It suits single-phase immersion cooling and cold plate or tube direct cooling. It also cools semiconductor equipment such as ion implanters, dry etchers and CVD machines, and suits dielectric testing.
Lower Pump Energy
Low kinematic viscosity (0.71 cSt at 20°C) reduces pump energy consumption. In addition, very low surface tension (15 dynes/cm) and excellent thermal conductivity support efficient heat transfer from -28°C to 85°C.
Is Thermasolv CF4 Safe for Live Equipment?
Yes. It has a dielectric strength of 40 kV (0.1″ gap at 25°C). So equipment can run under power while submerged. It is also non-flammable, with no flash point, and non-toxic, with no hazard classifications.
Material Compatibility
It is compatible with most metals, plastics and elastomers. However, we recommend testing it with your materials before use. It stays thermally and chemically stable in use, which supports long-term performance.
Why Choose Thermasolv CF4?
It combines low pumping costs with strong insulation and zero ODP. You can also recycle used fluid through Inventec’s Ecoprogram service. Therefore, it is a reliable choice for immersion, direct and semiconductor process cooling.
