Meguin Hydraulic Oil HEES 46 is a biodegradable hydraulic fluid based on high-quality synthetic esters. Has excellent viscosity temperature behavior. Can be used all year round thanks to excellent low-temperature behavior. EP additives and polar adhesion provide very good protection against wear, rust and corrosion. Rapidly biodegradable and miscible with all mineral oil-based products. Primarily for hydraulic systems in equipment that operates predominantly outdoors, is exposed to large temperature fluctuations and where there is a risk of higher environmental pollution due to leakage oil, e.g. mobile cranes and excavators in agriculture and forestry, floating dredgers, sluice hydraulics, slope equipment, etc.
