General features
Hydrol®
L-HL hydraulic oils for hydrostatic systems are manufactured basing on high
quality mineral base oils and a set of enriching additives improving
anticorrosive and antioxidative properties.
Application
Hydrol®
L-HL hydraulic oils are intended to be applied in low and medium loaded power
transferring systems and in hydraulic driving and control systems of
hydrostatic drive devices working with moderate temperatures.
