Mineral hydraulic fluids, having detergent and dispersant properties, conforming to the international standard ISO type HM. Formulated with base oils refined paraffinic solvent and additives to prevent oxidation and the formation of foam, to reduce the wear and prevent corrosion.

The HM are mainly used in hydraulic systems of machine tools and machinery for the hot molding of plastics and rubber, in the commands of the clutches and mobile hydraulics. They are especially suitable for machine tools with pneumatic or electromagnetic clutches with oil bath drives. The detergent and dispersant characteristics are prevented by the jam of the valves and clogging of filters in hydraulic systems for molding plastics numerical control machine tools and presses, reducing maintenance interventions and allowing significant efficiency gains. Meet the specification DIN 51524. In particular, the '100 HM (level VCL DIN 51506) is used as crankcase oil in large diesel engines with separate lubrication.
