LISOL HYDRAULIC OIL BIO HEES 46 B – Fully Synthetic, Biodegradable Ester-Based Hydraulic Fluid
LISOL HYDRAULIC OIL BIO HEES 46 B is a fully synthetic high-performance hydraulic oil formulated from a blend of saturated and unsaturated synthetic esters.
It offers excellent lubricity, very high thermal and oxidative stability, improved low-temperature performance, and an extended operating temperature range, enabling longer drain intervals.
Due to its rapid biodegradability, BIO HEES 46 B is ideal for machinery and hydraulic systems operating in environmentally sensitive areas, such as forestry, water management, municipal applications and soil-critical zones.
The product does not attack common industrial paints but should not be mixed with mineral oil–based hydraulic fluids. When converting existing systems, follow OEM guidelines and VDMA 24569.
