HEES Synthetic Hydraulic Fluid
Biodegradable synthetic ester hydraulic fluid for forestry, wind energy and civil construction machinery
Biodegradable HEES (Hydraulic Environmental Ester Synthetic) hydraulic fluid based on synthetic esters for hydraulic systems in environmentally sensitive environments. Synthetic esters provide superior biodegradability (≥60% in 28 days per OECD 301B) combined with the best technical performance of EAL fluids: excellent low-temperature behaviour, high viscosity index (VI >150), long service life and full compatibility with seals and paints of conventional hydraulic systems. Complies with the European Ecolabel and the EAL criterion of US EPA VGP. Recommended for hydraulic systems of forestry machinery (excavators, felling machines), wind turbines, civil construction machinery in protected areas and nautical machinery. Available in ISO VG 32, 46 and 68.
