Thermasolv IM7 is a dielectric heat transfer fluid from Inventec Performance Chemicals. It is designed for single-phase and two-phase immersion and direct cooling systems.
Key Features of Thermasolv IM7
- Pour point -138°C / -216°F
- GWP of 61
- Perfect for single or two-phase
What Is Thermasolv IM7 Used For?
It suits single-phase and two-phase immersion cooling, plus cold plate or tube direct cooling. Typical uses also include dielectric testing and specialised manufacturing cooling.
Single or Two-Phase Cooling
With a boiling point of 76°C, it can run as a single-phase coolant or boil at hot surfaces in two-phase systems. As a result, it adapts to a wide range of cooling designs.
Low Pump Strain
A very low pour point of -138°C and low kinematic viscosity (0.43 cSt at 20°C) reduce pump strain. In addition, thermal conductivity of 0.069 W/m-K and surface tension of 13.6 dynes/cm support efficient heat transfer.
Is Thermasolv IM7 Safe With Live Electronics?
Yes. Its dielectric strength is over 25 kV, with resistivity of 1.00E+08 Ohm-cm. So equipment can run under power while fully submerged. It is also non-flammable and non-toxic, with no storage hazards.
Why Choose Thermasolv IM7?
It has a very low GWP of 61, zero ODP and Inventec’s Greenway designation. It also offers excellent compatibility with metals, plastics and elastomers. Moreover, you can recycle used fluid through the Ecoprogram. Therefore, it is a versatile, sustainable immersion fluid.
