Dongsen L-HV Low Temperature High Viscosity Anti wear hydraulic oil is a line of premium quality anti wear lubricants blended using selected and highly refined high quality mineral oils, combined with a multifunctional additive system and available in a wide viscosity range from ISO Grade 15 to 100.They are known as:

◎High viscosity index combined with low pour point ensures excellent low-temperature fluidity and provides excellent low-temperature start up, protecting the hydraulic system from wear and extending life

◎Excellent oxidation stability helps reduce maintenance downtime and costs by contributing to system cleanliness and deposit reduction, enable long oil and filter life

◎Outstanding anti-wear performance, significantly reducing the wear of machine parts extend component life and improve production capacity

◎Intentional hydrolytic stability, reducing equipment damage caused by water pollution

◎Excellent anti-foaming and air release properties, to ensure that the system is sensitive, accurate and stable to transmit static pressure energy

◎Great viscosity-temperature behaviour , stability and resistance to elevated temperatures.
