Nycodiel is a synthetic hydrocarbon-based fluid, with a viscosity of 5 cSt at 40°C. It is inhibited against oxidation.

Nycodiel is a new generation coolant for electronic systems, mainly military radar, embarked on aircraft, ships or ground equipment. It does replace advantageously former coolants based on silicate esters. Nycodiel is not sensitive to water and does exhibit a stable flash point during use and does not produce gels which clog cooling systems and filters
