Biodegradable hydraulic fluid based on high-quality synthetic esters. Has excellent viscosity temperature behavior. Due to outstanding cold-weather properties, can be used year-round. EP additives and the polar adhesion provide very good protection against wear, rust and corrosion. Rapidly biodegradable and miscible with all mineral oil-based products. Mainly for hydraulic systems in equipment which primarily operates outside, is subjected to large fluctuations in temperature and where there is a risk of a high degree of pollution through oil leakage. Examples are mobile cranes and excavators in agriculture and forestry, floating dredgers, sluice hydraulic systems, snowcats, etc.
