NYCODIEL

HYDROLYTICALLY STABLE, DIELECTRIC COOLANT FLUID

NYCODIEL is made out of synthetic hydrocarbon stabilized against oxidation; it is a microfiltered product. It has been specially developed to overcome problems encountered in the use of silicate fluids as dielectric coolants in radars and ECM. NYCODIEL is not sensitive to water. Consequently it exhibits a stable flash point during use and will not produce gel which clogs cooling systems and which is also an arcing source.
