HYDROL PREMIUM L-HV hydraulic oils are HVI oils, which are obtained on the basis of refined mineral oils and non-honic packing of refining additives. These oils are characterized by: high level of performance properties, excellent viscosity-temperature characteristics (viscosity index 150) allowing the use of the oil in hydraulic systems operated under variable temperature conditions, high thermal and hydrolytic stability, high resistance to oxidation, high load carrying capacity (FZG test, destructive load grade >12), very good anti-wear properties, very good filterability, high foam resistance, compatibility with seals.
