Hydraulic systems (or circuits) consist in a set of components filled with a fluid that is responsible for energy transmission with great flexibility and under controlled conditions. Hydraulic oils in this system must have technical characteristics and performance suitable for every kind of machinery and operative conditions, in order to ensure good operation of the systems and provide relevant protection of all lubricated components to extend their service life. Eni, according to technological standards, produces modern and advanced mineral or synthetic lubricants suitable for any kind of hydraulic systems. Synthetic oils are specifically required where a greater environmental protection (biodegradability) or a greater protection from fire hazard (fire resistant) is required. Eni has recently introduced a new range of products specifically developed for food industry, FDA and NSF certified.
