Mobil DTE Excel SeriesHydraulic Oil

Product DescriptionMobil DTE Excel Series oils are supreme performance hydraulic oils developed for use in high-speed,high-pressure piston, vane and gear pumps. They are formulated from high quality base stocks and speciallyselected super-stabilised additives. Their advanced technology ashless anti-wear additive system was developedto give exceptional corrosion protection for copper-based alloys in severe hydraulic applications such ashigh-pressure axial piston pumps. This unique additive system also gives the Mobil DTE Excel Series excellentcompatibility with coolants used in metal working applications.

The Mobil DTE Excel Series oils exhibit excellent oxidation and thermal stability properties which results inextended oil and filter life while providing optimum equipment protection reducing both maintenance and productdisposal costs. They were developed in conjunction with the major OEMs to meet the stringent requirements ofsevere hydraulic systems using high pressure, high output pumps as well as handling the critical requirementsof other hydraulic system components such as close clearance servo-valves and the high accuracy numericallycontrolled (NC) machine tools. They are designed to work with systems operating under moderate to severeconditions where high levels of anti-wear and film strength protection are needed, yet they are formulated towork where non-anti-wear hydraulic oils are generally recommended.

Features and BenefitsThe Mobil DTE Excel Series hydraulic oils exhibit outstanding high temperature performance providing an extramargin of equipment protection. Their excellent oxidation resistance and thermal stability characteristics allowextension of oil and filter change intervals while assuring exceptionally clean systems and trouble-free operation.Their high level of anti-wear properties and excellent film strength characteristics result in exceptional equipmentperformance that not only results in fewer breakdowns but helps improve production capacity. Their controlleddemulsibility permits the oils to work well in systems contaminated with small amounts of water yet readilyseparate large amounts of water readily.
