Where water is not applicable and an inert dielectric liquid is required PFCs provide an extremely effective solution with high heat transfer coefficient and excellent materials compatibility. This keeps the component temperatures lower and thus reduces failure rates of high sophisticated electronics and increased reliability. At the same time, components can be packed closer together to maximise power density and minimise equipment size. PFC-5-1-14 (C6F14 – Perfluorohexane) is the preferred replacement of niche market dielectric heat transfer applications using CFC-113. Based on the inert properties and high dielectric strength (>15kV/mm) PFC liquids have also been specified also in international military standards for radar cooling.
Exceedingly stable, PFCs have been designed to be compatible with sensitive materials of construction such as metals, plastics and elastomers. They are clear, colourless, odorless, non-flammable and practically non-toxic liquids.
Since PFCs are inert liquids mainly used in closed system heat transfer applications they are typically recovered, recycled and reused as the product market value is very high for these speciality chemicals.
