BIOHYD OPTI (HEPR)

BIOHYD OPTI is a high-performance, renewable hydrocarbon-based (PAO) environmentally acceptable hydraulic fluid (EALs). On the scale of biodegradable hydraulic fluids HEPR is a well-balanced combination of biodegradability and quality of fully synthetic PAO base oils.

BIOHYD OPTI provides a very high level of thermo-oxidative and hydrolytic stability at both high and extremely low operating temperatures. Its modern, zinc-free and ash-free additive technology guarantees maximum lubrication reliability, shear stability and corrosion protection.

BIOHYD OPTI features a low foaming tendency, and good water and air release characteristics, as well as compatibility with seal materials. BIOHYD OPTI is readily biodegradable product for reduced environmental footprint.
